OPG „Antun Martinović“ osnovano je 2009. godine u Starim Mikanovcima. Na OPG-u rade članovi obitelji, te jedna zaposlena osoba. Gospodarstvo obrađuje površinu koja iznosi 94 hektara, od toga je dio vlastite površine, a dio u zakupu. U ovome radu analizirana je proizvodnja suncokreta tijekom 2022. godine. Količina oborina bila je manja u odnosu na višegodišnji prosjek 1899.-2021., a iznosila je 221,9 mm odnosno 109,3 mm manje. Vegetacij-ska sezona bila je toplija od višegodišnjeg prosjeka za 1,6 °C. Možemo reći da je godina bila u skladu s prosjekom, uz nešto manje oborina. Ostvareni prinos zrna suncokreta iznosio je oko 3,9 t/ha uz vlagu zrna od 7,8 %. Sadržaj ulja iznosio je oko 40 % uz 90 % sadržaja oleinske kiseline. Zaključno, nešto nepovoljnija vegetacijska sezona u pogledu oborina i temperatura, ali su ostvareni vrlo dobri urodi zrna što potvrđuju i saznanja iz šire poljopirvredne proizvodnje., OPG "Antun Martinović" was founded in 2009 in Stari Mikanovci. Family members and one employed person work at OPG. The farm cultivates an area of 94 hectares, of which part is owned and part is leased. In this paper, the production of sunflowers during 2022 was analyzed. The amount of precipitation was less compared to the multi-year average of 1899-2021, and amounted to 221.9 mm and 109.3 mm less, respectively. The growing season was warmer than the long-term average by 1.6 °C. We can say that the year was in line with the average, with slightly less precipitation. The realized yield of sunflower seeds was about 3.9 t/ha with a moisture content of 7.8%. The oil content was about 40% with 90% oleic acid content. In conclusion, a slightly less favorable growing season in terms of precipitation and temperature, but very good grain yields were achieved, which is also confirmed by findings from wider agricultural production.

Soja (Glycine max L.) je ratarska kultura koja se uzgaja više od 4000 godina, a donešena je u Europu krajem 17. Stoljeća. Za razliku od ostalih jednogodišnjih kultura soja je najznačajnija proteinska i uljna kultura u svijetu jer proizvodi najviše bjelančevina. Zrno soje sadrži 35-55 % bjelančevina i 18-24 % ulja. U Hrvatskoj se sije na oko 90 000 ha. Na OPG-u Ivan Sabo soja se sije na 25 ha. Sorta soje koju koriste je sorta I. grupe zriobe i naziva se IKA i sa tom sortom ostvaruju prinose od oko 4 t/ha, sa sadržajem ulja od 20-22 %. Količina sjemena za sjetvu je 140 kg. U ekološkoj poljoprivrednoj proizvodnji raspolažu sa 80 ha, a uz soju uzgajaju se i druge ratarske kulture: suncokret (25 ha), pir (10 ha), pšenica (20 ha)., Soy (Glycine max L.) is a field crop that has been cultivated for more than 4,000 years, and was brought to Europe at the end of the 17th century. Unlike other annual crops, soy is the most important protein and oil crop in the world because it produces the most protein. Soybeans contain 35-55 % protein and 18-24 % oil. In Croatia, it is sown on about 90,000 ha. At OPG Ivan Sabo, soybeans are sown on 25 ha. The variety of soybeans they use is the variety of the I. maturation group and is called IKA, and the average yield achieved with this variety is 4 t/ha, with an oil content of 20-22 %. The amount of seed for sowing is 140 kg. In ecological agricultural production, they have 80 ha, and in addition to soybeans, other crops are grown: sunflower (25 ha), spelt (10 ha), wheat (20 ha).

Prinos zobi na OPG-u “Đipan“ iznosio je 3,4 t/ha. Masa 1000 zrna iznosila je 32 g, hektolitarska masa bila je 47 kg, a sadržaj bjelančevina 10 %. Zob se najvećim dijelom koristi za hranidbu stoke, zatim ljudsku prehranu te ostale namjene. Prosječni prinosi zobi u svijetu su oko 2,2 t/ha, a kod nas oko 2,8 t/ha. Zob nema velike zahtjeve prema temperaturi i tlu, ali treba više vode u odnosu na druge žitarice. Uzgaja se u plodoredu gdje obično dolazi na zadnje mjesto. Jara zob se gnoji sa 60-90 kg/ha N, 60-80 kg/ha P2O5, 70-110 kg/ha K2O, na plodnim tlima. Ozima zob se gnoji sa 80-100 kg/ha N, 60-80 kg/ha P2O5 , 70-110 kg/ha K2O. Optimalna gustoća sjetve zobi je 300-600 zrna /metru kvadratnom. Ozima zob se sije u prvoj polovici listopada, a jara krajem veljače ili početak ožujka. Žetva zobi se obavlja sa žitnim kombajnom u drugoj dekadi srpnja., Oat yield at OPG "Đipan" was 3.4 t/ha. The weight of 1000 grains was 32 g, the hectoliter weight was 47 kg, and the protein content was 10%. Oats are mostly used for feeding cattle, then for human consumption and other purposes. Average oat yields in the world are around 2.2 t/ha, and in our country around 2.8 t/ha. Oats do not have great requirements for temperature and soil, but they need more water than other cereals. It is grown in the crop rotation where it usually comes last. Spring oats are fertilized with 60-90 kg/ha N, 60-80 kg/ha P2O5, 70-110 kg/ha K2O, on fertile soils. In winter, oats are fertilized with 80-100 kg/ha N, 60-80 kg/ha P2O5, 70-110 kg/ha K2O. The optimal sowing density of oats is 300-600 grains / square meter. Winter oats are sown in the first half of October, and spring oats in late February or early March. Oats are harvested with a grain harvester in the second decade of July.

U ovom završnom radu opisana je ekološka proizvodnja boba u Laslovu 2022., nakon koje su analizirane komponente prinosa boba. U ovom radu cilj je bio odrediti visinu biljke (cm), broj mahuna po biljci i masu biljke, te dužinu mahune (cm), broj zrna u mahuni i masa zrna u mahuni (g).

Prosječno su mahune u sebi imale 7 zrna, a masa svih zrna u jednoj mahuni iznosila je prosječno 1,5 g. Izmjerena svojstva su bila relativno niska zbog utjecaja suše tijekom vegetacije boba u 2022. godini. Ostvareni prinos zrna boba bio je 0 kg/ha zbog nemogućnosti strojne vršidbe usjeva, uslijed prevelike zakorovljenosti., In this graduauauate thesis, the ecological production of faba beans in Laslovo in 2022 is described, after which the components of the yield were analyzed. In this thesis, the aim was to determine the height of the plant (cm), the number of pods per plant and the weight of the plant, as well as the length of the pod (cm), the number of grains in the pod and the weight of the grains in the pod (g). The height of the plants ranged from 39 to 88 cm, with an average of 60.7 cm. The total weight of the plant was an average of 13.2 g per plant. The average length of the pod was 7 cm. On average, the pods contained 7 grains, and the mass of all grains in one pod was 1.5 g. The measured properties were relatively low due to the influence of drought during the bean growing season in 2022. The harvested yield of faba beans was 0 kg/ha due to the impossibility of mechanical harvesting of the crop due to excessive weediness..

Završni rad prikazuje proizvodnju kukuruza na OPG Dukmenić u Vukojevcima tokom vegetacijske sezone 2022. Na OPG-u Dukmenić najčešće se uzgajaju hibridi Osječkog poljoprivrednog instituta i to hibrid OS Kulak. Agrotehničke mjere koje prate uzgoj kukuruza, na OPG-u su provedene pravovremeno primjenom vlastite raznovrsne poljoprivredne mehanizacije. Tla u vlasništvu OPG Dukmenić su povoljna za uzgoj kukuruza i drugih žitarica. Na OPG-u Dumenić se poštuje plodored. OPG na svojim površinama većinom nastoji izmjenjivati kukuruz, ječam, pšenicu i suncokret. Obrada i priprema tla su odrađene kvalitetno i u adekvatnom roku jer je predusjev bio pšenica. Sjetva je obavljena u optimalnom roku 23. i 24 . travnja hibridom OS Kulak. Pojavljeni korovi u kukuruzu nisu utjecali na prinos. Vremenski uvjeti tijekom rasta i razvoja kukuruza su bili nepovoljni zbog ekstremne suše. Mjerenjem klipa utvrđeno je da je prosječna masa cijelog klipa 237 grama, masa zrna 178,3 grama a masa samog otučka 58,7 grama. Prema rezultatima mjerenja utvrđeno je da je prosječan prinos 1,37 kilograma vlažnog zrna na m2., The final paper shows the production of corn at OPG Dukmenić in Vukojevci during the growing season of 2022. Hybrids of the Osijek Agricultural Institute are most often grown at OPG Dukmenić, namely the OS Kulak hybrid. Agrotechnical measures accompanying the cultivation of corn were carried out at OPG in a timely manner by using our own diverse agricultural machinery. The soils owned by OPG Dukmenić are favorable for growing corn and other cereals. At OPG Dumenić, crop rotation is respected. OPG mostly tries to alternate corn, barley, wheat and sunflower on its areas. Cultivation and preparation of the soil were done with quality and in an adequate time, because the pre-crop was wheat. Sowing was done at the optimal time on the 23rd and 24th. April by the OS Kulak hybrid. The weeds that appeared in corn did not affect the yield. Weather conditions during the growth and development of corn were unfavorable due to extreme drought. By measuring the cob, it was determined that the average weight of the entire cob is 237 grams, the weight of the grain is 178.3 grams, and the weight of the stem itself is 58.7 grams. According to the measurement results, it was determined that the average yield is 1.37 kilograms of wet grain per m2.

Završni rad prati proizvodnju pšenice na OPG Mišić u Strizivojni tijekom vegetacijske sezone 2021./2022. Na OPG Mišić uzgajala se samo sorta Kraljica koja se na oranicama nalazi već nekoliko godina. Agrotehničke i mehaničke mjere na OPG provedene su ispravno pomoću razne mehanizacije koju OPG posjeduje. Tla koja posjeduje OPG su pogodna za uzgoj pšenice i obavezno se poštuje plodored. OPG ne uzgaja puno ratarskih kultura, te se teži tome da svake godine na oranici predusjev za pšenicu bude kukuruz, koji se u zadnjih nekoliko godina i pokazao kao najbolji predusjev. Osnovna obrada i predsjetvena priprema tla su provedene u optimalnom roku jer se kukuruz skinuo vrlo rano, a vremenske prilike su bile povoljne. Sjetva je obavljena u optimalnom roku sortom Kraljicom, tavanušom iz predhodne vegetacije. Mjere njege su napravljene prema pravilima struke, te korovi i štetnici koji su se pojavili nisu imali utjecaj na prinos., The final work followers the production of wheat at the family farm Mišić during the growing season 2021./2022. Only the variety Queen which has been in the fields for several years was grown on the Mišić family farm. Agrothenical ande mehanichal mesures on the family farm were carred out corretly using various mechanization owned by the family farm. The soil owned by the family farm is suitable for growing whet and crop rotation must be respected. The family farm does not grow a lot of field crops so it strives to have maize pre-sowing for wheat every year, which has proven to be the best pre-sowing in the last few years. Basic tillage and pre-sowing soil preparation were carried out in the optimal time because the corn was harvested very early and the weather conditions were favorable. Sowing was done in the optimal time with the variety Queen, a ceiling from the previous vegetation. Care measures were made according to the rules of the profession, and weeds and pests that appeared did not affect the yield.

The paper presents crop protection, quality, fertilization, planting, harvesting and all other agrotehnical measures. In addition to crop protection, irrigation is one of the most important tehnological measures affecting yields. Data from the state institute of surface potato statistics in Croatia were used for this work.

Kolika je važnost poljoprivrede govori i činjenica kako se gotovo jedna polovica čovječanstva bavi poljoprivredom te im je to i primarna djelatnost koja im je glavni izvor egzistencije. Suncokret (Helianthus annuus L.) je ratarska kultura od krucijalne važnosti za proizvodnju jestivog ulja, kako u svijetu tako i u Republici Hrvatskoj. U razdoblju 2004. - 2013. godine, suncokret se u svijetu uzgajao na prosječno 24 milijuna hektara godišnje s prosječnim urodom zrna od 1,40 t/ha. Za postizanje visokih uroda potrebno je biljkama stvoriti povoljne uvjete za rast i razvoj pa tako i kod suncokreta. Mjere koje to omogućuju ukratko imaju naziv agrotehničke mjere ili agrotehnika, a to su: plodored, obrada tla, sjetva, gnojidba, njega i zaštita bilja te žetva., The importance of agriculture is also borne out by the fact that almost one half of humanity is engaged in agriculture, and this is their primary activity, which is their main source of livelihood. Sunflower (Helianthus annuus L.) is a crop-growing crop of crucial importance for the production of edible oil, both worldwide and in the Republic of Croatia. In the period 2004-2013, sunflower is grown worldwide on an average of 24 million hectares per year with an average grain yield of 1.40 t / ha. To achieve high yields, plants need to create favorable conditions for growth and development, including sunflower. Measures that make this possible are called agrotechnical measures or agrotechnics, which are: crop rotation, tillage, sowing, fertilization, care and plant protection, and harvest.

U ovom radu analizirana je tehnologija proizvodnje suncokreta na OPG-u „Vjekoslav Šmider“ u 2019. godini. Usjev suncokreta je iznosio 3,2 t/ha, apsolutna težina zrna je iznosila 85 g, a uljnost je bila 48 %. Ova godina je bila izuzetno povoljna za uzgoj suncokreta. Uzmemo li u obzir da je zbog kišnog razdoblja u travnju sjetva bila pomaknuta za par dana, to nije negativno utjecalo na početni rast i razvoj suncokreta. Svibanj bilježi suficit oborina od 89,4 mm od višegodišnjeg prosjeka. Ta velika količina oborina nije negativno utjecala na suncokret jer je bila raspoređena tijekom cijelog mjeseca. Manje količine oborina smo imali u srpnju no to se nije odrazilo na suncokret jer je od prijašnjih mjeseci imao dovoljno vlage za kvalitetno sazrijevanje. U kolovozu je pala prosječna količina oborina koja nije ništa značila jer je suncokret bio u fazi sazrijevanja i nalijevanja zrna., In this paper, the technology of sunflower production on the family farm "Vjekoslav Šmider" in 2019 is analyzed. The sunflower crop was 3.2 t/ha, the absolute grain weight was 85 g, and the oil content was 48 %. This year was extremely favorable for sunflower cultivation. If we take into account that due to the rainy period in April sowing was postponed by a few days, this did not negatively affect the initial growth and development of sunflower. May recorded a surplus of precipitation of 89.4 mm from the multi-year average. This large amount of precipitation did not negatively affect the sunflower as it was distributed throughout the month. We had smaller amounts of precipitation in July, but this did not affect the sunflower because it had enough moisture from previous months for quality ripening. In August, the average amount of precipitation fell, which meant nothing because the sunflower was in the phase of ripening and pouring the grain.

Tema završnog rada je tehnologija proizvodnje kukuruza u poduzeću „Agro Bovis d.o.o.“. Kukuruz je jednogodišnja kultura koja se uzgaja za prehranu ljudi ali u većoj mjeri za ishranu stoke. Kukuruz ima određene zahtjeve prema svjetlosti, vodi, klimi i tlu. Na „Agro Bovis d.o.o.“ predstavlja najznačajniju kulturu te je najveći dio površina zasijano istom. Oborine su veoma važne u rastu i razvitku stabljike kukuruza. U radu je prikazana agrotehnika proizvodnje kukuruza na „Agro Bovis d.o.o.“. Vegetacijska godina 2019. bila je izrazito povoljna za proizvodnju kukuruza i isti su ostvarivali rekordne prinose., The topic of the final work is the technology of corn production in the company "Agro Bovis d.o.o.". Maize is an annual crop that is grown for human consumption but to a greater extent for livestock nutrition. Corn has certain requirements for light, water, climate and soil. At "Agro Bovis d.o.o." it represents the most important crop and most of the areas are sown with the same. Precipitation is very important in the growth and development of the corn stalk. The paper presents the agrotechnics of corn production at "Agro Bovis d.o.o." The vegetation year 2019 was extremely favorable for the production of corn and they achieved record yields.

U ovom radu analizirana je proizvodnja ječma na obiteljskom poljoprivrednom gospodarstvu „Funarić Dražen“. Na gospodarstvu se uzgaja ozimi ječam, koji je se koristi za ishranu stoke. Nicanje je bilo malo otežano, ali pravilni agrotehnički zahvati i stručno znanje je rezultiralo odličan prinos. Vegetacijska godina 2018.i 2019. bila je u početku vrlo sušna, ali onda pred kraj vegetacije su pale velike količine oborina. Za ovakvu tešku godinu ostvareni su odlični prinosi ječma (Maxim-Poljoprivredni institut Osijek) koji su iznosili 7,4 t/ha., In this paper, the production of barley on the family farm "Funarić Dražen" is analyzed. The farm grows winter barley, which is used to feed livestock. Germination was a little difficult, but proper agronomic interventions and expertise resulted in excellent yields. The vegetation year 2018 and 2019 was initially very dry, but then towards the end of the vegetation large amounts of precipitation fell. For such a difficult year, excellent barley yields were achieved (Maxim-Agricultural Institute Osijek) which amounted to 7.4 t per hectare.

U ovom radu analizirana je proizvodnja pšenoraţi na obiteljskom poljoprivrednom gospodarstvu „Galinović Danijel“. Agrotehniĉke mjere su obavljene prema pravilima struke. Prinos je iznosio 4,5 t/ha s obzirom na temperature i oborine tijekom 2017/2018. godine. Najkritiĉniji je bio mjesec srpanj kada je palo 131,6 mm oborina te se ţetva teţe odvijala. TakoĊer, u travnju i svibnju je trajala suša koja nije negativno utjecala na pšenoraţ, što znaĉi da pravovremena priprema tla, gnojidba i korištenje herbicida uvelike pomaţu povećati prinos., This paper analyzes the production of triticosecale on the family farm "Galinović Danijel". Agrotechnical measures were carried out according to the rules of the profession. The yield was 4.5 t/ha with regard to temperatures and precipitation during 2017/2018. The most critical month was July, when 131,6 mm of precipitation fell and the harvest was more difficult. Also, in April and May there was a drought that did not negatively affect the triticosecale, which means that timely soil preparation, fertilization and use of herbicides greatly help to increase yields.

Cilj rada je analiza proizvodnje lucerne na površinama VUPIK PLUS-a d.o.o Vukovar u sezoni 2018./2019. Lucerna (kultivar Osječka 66) je uzgajana na 175 ha (godinu dana starosti), 53 ha (tri godine starosti) i 50 ha (četiri godine starosti), što ukupno iznosi 278 ha. Praćeni su klimatski pokazatelji (srednja mjesečna temperatura zraka i ukupne mjesečne oborine) te uspoređeni s višegodišnjim prosjecima za ovo područje. Sve agrotehničke mjere u uzgoju lucerne provedene su pravodobno i prema preporukama struke. Uočeno je smanjenje prinosa zelene mase sa starošću lucerne i povećanjem broja otkosa. Ukupni prinos zelene mase lucerne svih starosti sa svih parcela i u svim otkosima iznosi 4 562 860 kg, što daje prosjek od 16 413,16 kg/ha. Prvi i drugi otkos iskorišteni su za spremanje sjenaže, a treći i četvrti za spremanje sijena. Prihod od proizvodnje izračunat je na bazi cijene sjenaže od 0,55 HRK/kg i cijene sijena od 0,25 HRK/kg. Ukupni prihod proizvodnje lucerne iznosio je 2 325 910,00 HRK ili 8 366,58 HRK/ha., The aim of this paper is to analyze the production of alfalfa on the surfaces of VUPIK PLUS d.o.o Vukovar in the season 2018/2019. Alfalfa (cultivar Osječka 66) was grown on 175 ha (one year of age), 53 ha (three years of age) and 50 ha (four years of age), for a total of 278 ha. Climatic indicators (average monthly air temperature and total monthly precipitation) were monitored and compared with multi-year averages for this area. All agro-technical measures in alfalfa cultivation were carried out in a timely manner and according to the recommendations of the profession. A decrease in green mass yield was observed with the age of alfalfa and an increase in the number of cuttings. The total yield of alfalfa green mass of all ages from all plots and in all cuttings is 4,562,860 kg, which gives an average of 16,413.16 kg ha-1. The first and second cuttings were used to store haylage, and the third and fourth to store hay. Production income was calculated on the basis of the price of haylage of 0.55 HRK kg-1 and the price of hay of 0.25 HRK kg-1. The total income of alfalfa production amounted to HRK 2,325,910.00 or HRK 8,366.58 ha-1.

U ovom radu analiziran je utjecaj agrotehnike i vremenskih uvjeta na proizvodnju pivarskog ječma na OPG Lović Tomisav u 2019./2020. godini. Mjere agrotehnike koje su provedene rezultat su preporuke struke i osobnog iskustva u proizvodnji žitarica. Sve mjere agrotehnike su provedene na vrijeme na osnovi podataka dobivenih iz Državnog hidrometeorološkog zavoda s mjerne postaje Slavonski Brod. Možemo zaključiti da je 2019./2020. godina bila topla i sušna s temperaturama većim od prosjeka, te manjim količinama oborina u odnosu na prosjek. Iz svega navedenog prinos od 7 t/ha može se smatrati zadovoljavajućim., This paper examines the impact of agrotechnics and weather conditions at malting barley production on the family farm Lović Tomislav in 2019./2020.. The agrotehnical measures that have been implemented are the result of the recommendations of the profession and personal experience in the production of grains. All agro-tehnical measures where implemented on time, based on the data of State Hydrometeorological Institute from the measuring station Slavonski Brod. We can conclude that 2019./2020. year was warm and dry with temperatures above average, and with smaller amounts of rainfall then average. From all the above, we conclude the yield of 7 t/ha can be considered satisfying.

Obiteljsko poljoprivredno gospodarstvo (OPG) Lasić Franjo osnovano je 2001. godine u Đakovu i bavi se ratarskom proizvodnjom na 65 ha oranica. Trenutno ima dva zaposlena člana obitelji koji proizvode žitarice i uljarice, odnosno pšenicu, ječam, zob, kukuruz, soju i suncokret. OPG Lasić Franjo posjeduje svu potrebnu mehanizaciju koja se koristi u intenzivnoj proizvodnji. U procesu proizvodnje OPG poštuje plodored i pravilno provodi agrotehničke operacije, a naročito se pozornost posvećuje zaštiti usjeva. Vegetaciju kukuruza 2018. karakterizira manja količina oborina (360 mm) i veće prosječne temperature zraka (19,7 °C) dok je u 2019. ukupna količina oborina iznosila 608 mm uz nešto niže prosječne temperature zraka (18,4 °C). Tijekom vegetacije pšenice vremenske prilike nisu bile toliko različite uz naglasak na drugačiju distribuciju oborina. Uslijed provedene agrotehnike i vremenskih prilika prosječan prinos kukuruza u 2018. je iznosio 11,5 t/ha, a 2019. 12,6 t/ha dok je u slučaju pšenice razlika između godina bila minimalna (7,2 t/ha i 7,3 t/ha)., Family farm Lasić Franjo was founded in 2001 in Đakovo and is engaged in crop production on 65 ha of arable land. Currently he has two employed family members who produce cereals and oilseeds such as wheat, barley, oats, corn, soybeans and sunflowers. Furthermore, family farm Lasić Franjo has all the necessary mechanization used in intensive production. In the production process, the family farm respects the crop rotation and properly carries out agro-technical operations, and special attention is paid to crop protection. Maize vegetation in 2018 is characterized by lower rainfall (360 mm) and higher average air temperature (19.7 ° C), while in 2019 the total rainfall was 608 mm with slightly lower average air temperature (18.4 ° C). During wheat vegetation, the weather conditions were not so different, except there was a different distribution of precipitation. Due to the conducted agricultural techniques and weather conditions, the average yield of maize in 2018 was 11.5 t/ha and in 2019 12.6 t/ha, while in the case of wheat the difference between the years was minimal (7.2 t/ha and 7.3 t/ha).

U ovom radu analizirana je tehnologija proizvodnje ozimog ječma na OPG-u „Matija Krstanac“ u vegetacijskoj godini 2018.-2019. godini. Agrotehničke mjere od obrade tla do same žetve usjeva obavljene su u skladu s pravilima struke. Usjev ozimog ječma s obzirom na vremensku prognozu koja je pratila 2018.-2019. godine dala je zadovoljavajući prinos od 7 t/ha na površinama zasijanim na 10 ha. U radu su korišteni podaci Državnog hidrometeorološkog zavoda o vremenskim prilikama za meteorološku postaju Gorice.Vidljivo je da je vegetacijska 2018.-2019. godina bila suprotna u odnosu na višegodišnji prosjek. Vegetacijska godina 2018.-2019. bila sa manje oborina i većim mjesečnim temperaturama zraka u odnosu na višegodišnji prosjek 1961.-1990.Manjak oborina u listopadu nije pravio problema usjevu ječma za sjetva, a niti prilikom klijanja i nicanja. U svibnju oborina je palo više nego od višegodišnjeg prosjeka, što je dobro jer nam za nalijevanje i formiranje zrna treba dosta vlage., In this paper, the technology of winter barley production on the family farm "Matija Krstanac" in the vegetation year is analyzed 2018.-2019. year. Agrotechnical measures from tillage to the harvest of crops were carried out in accordance with the rules of the profession. Winter barley crop given the weather forecast that accompanied 2018-2019. year gave a satisfactory yield of 7 tons / hectare on areas sown on 10 hectaresThe paper uses data from the State Hydrometeorological Institute on weather conditions for the Gorica meteorological station. It can be seen that the vegetation 2018-2019. year was the opposite of the multi-year average. Vegetation year 2018-2019 was with less precipitation and higher monthly air temperatures compared to the multi-year average of 1961-1990. The lack of precipitation in October did not cause problems for the barley crop for sowing, nor during germination and germination. In May, precipitation fell more than the multi-year average, which is good because we need a lot of moisture to pour and form grain.

U ovome radu je ispitivan utjecaj agrotehnike i vremenskih prilika na urod soje na OPG-u „Mandić“ tijekom 2018. godine. Svi agrotehnički zahvati obavljeni su prema pravilima struke te pravovremeno analizirane godine. U istraživanju su korišteni podaci Državnog hidrometeorološkog zavoda o vremenskim prilikama za meteorološku postaju Slavonski Brod tijekom 2018. godine. Prosječni prinos je bio iznad prosjeka i iznosio je 4,6 t/ha. Temperature za vrijeme vegetacije, gotovo da nisu odstupale od višegodišnjeg prosjeka. Oborine su odstupale u travnju, kolovozu i rujnu, u smislu deficita, no to nije ostavilo ozbiljnije tragove na prinos soje., This paper investigated the influence of agrotechnics and weather conditions on soybean yield at OPG "Mandić" during 2018. All agricultural operations were performed according to the rules of the profession and analyzed in a timely manner. The data of the State Hydrometerological Institute on weather conditions for the Slavonski Brod metrological station were used in the survey during 2018. Average yield was above average and it was 4.6 t/ha. Temperatures during the growing season almost did not deviate from the perennial average. Precipitation declined in April, August and September in terms of deficits, but this did not leave any more serious impact on the soybean yield.

U ovom radu analiziran je utjecaj vremenskih prilika i pravovremeno izvođenje agrotehnike u proizvodnji silažnog kukuruza na OPG-u „Stjepan Sarošević“ u 2019. godini. Detaljno su opisane sve izvedene agrotehničke mjere koje su zasnovane na preporuci struke i vlastitog iskustva u proizvodnji te na osnovu podataka Državnog hidrometeorološkog zavoda s mjerne postaje Gradište. Iz svega navedenog možemo zaključiti kako je 2019. godina bila izrazito pogodna za proizvodnju silažnog kukuruza jer se postigao prirod od 77 t/ha silaže., This paper examines the impact of weather conditions and the timely implementation of agricultural techniques in the production of silage corn on the family farm "Stjepan Sarošević" in 2019. All performed agro-technical measures are described in detail, which are based on the recommendation of the profession and own experience in production, and on the basis of data from the State Hydrometeorological Institute from the measuring station Gradište. From all the above, we can conclude that 2019 was extremely suitable for the production of silage corn, where we achieved a yield of 77 t/ha of silage.

Cilj istraživanja ovog diplomskog rada je bio prikazati uzgoj i tehnologiju proizvodnje pšenice na OPG-u Ivica Jurić u Nijemcima na području Vukovarsko-srijemske županije tijekom vegetacijske godine 2018./2019. te analizirati utjecaj vremenskih uvjeta na prinos i kvalitetu zrna dvije sorte pšenice, Ingenio i Falado. Za analizu vremenskih prilika korišteni su podaci Državnog hidrometeorološkog zavoda, a za prikaz tehnologije proizvodnje interni podaci OPG-a. Pšenica je ukupno uzgajana na 20 ha ili na 40 % površina gospodarstva. Obje sorte su posijane u optimalnom roku, a tijekom vegetacije primijenjena je adekvatna tehnologija uzgoja te je praćen rast i razvoj usjeva. Glavna karakteristika vegetacijskog razdoblja je nepravilna raspodjela oborina uz izrazito sušnu jesen i kišovito proljeće, dok su temperature zraka uglavnom bile više u usporedbi s referentnim višegodišnjim prosjekom, ali je svibanj bio vrlo kišovit i hladniji. Početno sušno razdoblje je dovelo do poteškoća prilikom osnovne i dopunske obrade tla te do usporenog početnog porasta i neujednačenog sklopa, ali je veća količina kiše u travnju poboljšala stanje usjeva. Unatoč specifičnim vremenskim uvjetima i nešto slabijoj gnojidbi, postignuti su zadovoljavajući prinos i kvaliteta zrna obje sorte. Prosječan prinos je iznosio 6,1 t/ha, hektolitarska masa je bila iznad 78 kg/hl, a sadržaj proteina 13,6 % kod sorte Ingenio te 13,9 % kod sorte Falado te su obje sorte svrstane u I. kvalitativnu klasu., The aim of this research was to present the cultivation technology of wheat production at the Family farm Ivica Jurić farm in Nijemci in the Vukovar-Srijem County during the 2018/2019 growing season and to analyze the impact of weather conditions on grain yield and quality of two wheat cultivars, Ingenio and Falado. The data of the State Hydrometeorological Institute were used for the analysis of weather conditions, and the internal data of the family farm were used to show the production technology. Wheat is grown on a 20 ha or 40% of the total area of the farm. Both cultivars were sown at the optimum term and adequate agrotechnics was applied during the growing season and the growth and development of the crop was monitored. The main characteristic of the vegetation period is the irregular distribution of rainfall with extremely dry autumn and rainy spring, while air temperatures were generally higher compared to the reference perennial average, but May have been very rainy and cooler. The initial drought period caused difficulties in basic and supplementary tillage, a slow early grow and crop density, but a greater amount of rain in April significantly improved the wheat condition. Despite specific weather conditions and slightly weaker fertilization, satisfactory grain yield and quality of both varieties were achieved. The average yield was 6.1 t/ha, the hectolitre mass was above 78 kg/hl, and the protein content was 13.6% for the Ingenio variety and 13.9% for the Falado variety, which means that both varieties were classified in the first qualitative class.

Cilj završnog rada bio je analizirati proizvodnju žitarica odnosno prikazati provedene agrotehničke zahvate u proizvodnji kukuruza, pšenice i ječma na OPG-u Mirko Rumbočić tijekom dvogodišnjeg razdoblja (2018.-2019.). OPG je osnovano 2003. godine u Mohovu (Vukovarsko-srijemska županija) i bavi se ratarskom proizvodnjom na 105 ha obradivih površina. Posjeduje odgovarajuće objekte i gotovo svu potrebnu mehanizaciju. Sa stajališta vegetacije kukuruza vremenske prilike su bile povoljne jer su ukupne količine oborina bile na razini ili iznad višegodišnjeg prosjeka uz više prosječne temperature zraka što pogoduje razvoju kukuruza. U pogledu vegetacije ozimih žitarice analizirane godine karakteriziraju više prosječne temperatura zraka i različita količina oborina. Agrotehnika na gospodarstvu obavlja se u skladu sa preporukama struke. Posebna pozornost pridaje se zaštiti ratarskih kultura od bolesti, korova i štetnika jer su to i najčešći uzročnici smanjenja prinosa i kvalitete. Ostvareni prinosi kukuruza su se kretali od 11 do 14 t/ha, pšenice od 6,5 do 7,0 t/ha i ječma od 6,0 do 6,5 t/ha uz različitu količinu vlage zrna između analiziranih godina., The aim of the final work was to analyze the production of cereals and show the implemented agro-technical interventions in the production of corn, wheat and barley on the family farm Mirko Rumbočić during a two-year period (2018-2019). The family farm was founded in 2003 in Mohovo (Vukovar-Srijem County) and is engaged in crop production on 105 ha of arable land. Also, it has the appropriate facilities and almost all the necessary machinery. In the context of maize vegetation period the weather conditions were favorable because the total rainfall was at or above the multi-year average with higher average air temperatures which favors maize development. In terms of winter cereal vegetation, the analyzed years are characterized by higher average air temperatures and different amounts of precipitation. Agrotechnics on the farm is performed in accordance with the recommendations of the profession. Special attention is paid to the protection of field crops from diseases, weeds and pests because these are the most common causes of reduced yields and quality. Realized yields of corn ranged from 11 to 14 t/ha, wheat from 6.5 to 7.0 t/ha and barley from 6.0 to 6.5 t/ha with different amounts of grain moisture between the analyzed years.

Osnovni cilj rada bila je analiza proizvodnje, odnosno provedene agrotehnike pšenice i kukuruza na OPG-u Antun Žagar tijekom 2017. i 2018. godine. Obiteljsko poljoprivredno gospodarstvo osnovano je 2002. u Otoku, a obrađuje 81,88 ha oranica na kojima dominira proizvodnja kukuruza i pšenice. Za uzgoj kukuruza 2018. godina je bila povoljnija jer su količine oborina bile slične višegodišnjem prosjeku za razliku od 2017. kada je količina oborina bila manja za 45 mm. Istovremeno, temperature zraka su bile više u obje godine. Za uzgoj pšenice 2018. godina je bila također povoljnija zbog znatno većih količina oborina u usporedbi s promatranim prosjekom. Tijekom obje vegetacije napravljene su sve potrebne agrotehničke operacije. Sjetva kukuruza obavljena je 5. travnja 2017. godine te 11. travnja 2018. godine dok je sjetva pšenice za obje analizirane vegetacijske godine obavljena 15. listopada. Uslijed djelovanja vremenskih prilika i provedene agrotehnike prosječni prinos kukuruza je iznosio 11,0 t/ha, a pšenice 7,0 t/ha., The main goal of the work was the analysis of production, i.e. implemented agricultural techniques of wheat and corn on the family farm Antun Žagar during 2017 and 2018. The family farm was founded in 2002 in Otok, and cultivates 81.88 ha of arable land, which is dominated by the production of corn and wheat. For maize cultivation, 2018 was more favorable because the amount of precipitation was similar to the long term average, unlike 2017, when the amount of precipitation was lower by 45 mm. At the same time, air temperatures were higher in both years. For wheat cultivation, 2018 was also more favorable due to significantly higher amounts of precipitation compared to the observed average. During both vegetations, all necessary agro-technical operations were performed. Sowing of maize was performed on April 5, 2017 and April 11, 2018, while sowing of wheat for both analyzed vegetation years was performed on October 15. Due to the weather conditions and implemented agricultural techniques, the average yield of corn was 11.0 t/ha, and wheat 7.0 t/ha.

Cilj rada bio je analizirati proizvodnju pšenice i ječma na OPG-u Funarić u dvogodišnjem razdoblju (2018.-2019.) odnosno prikazati provedene agrotehničke zahvate u uzgoju pšenice i ječma te utjecaj vremenskih prilika na ostvarene prinose. Općenito, prinosi za obje analizirane kulture u obje godine su bili poprilično stabilni. Uspješnoj proizvodnji treba dodati ulogu provedene agrotehnike, a naročito zaštite te pravilan odabir sorti. Vegetacijsku sezonu 2017./2018. karakteriziralo je više oborina i veće temperature zraka u usporedbi s višegodišnjim prosjekom, a 2018./2019. manje oborina od višegodišnjeg prosjeka i više temperature zraka za 0,7 °C. U navedenim uvjetima prinosi pšenice su iznosili 6,7 t/ha i 6,5 t/ha, a ječma 6,8 t/ha i 7,6 t/ha u 2017./2018. odnosno u 2018./2019. S obzirom da se proizvodnja pšenice i ječma pokazala uspješnom ove dvije kulture imaju priliku i kapacitete rasta u budućim godinama na OPG-u., The aim of the study was to analyze the production of wheat and barley on the family farm Funarić in a two-year period (2018-2019) and to show the implemented agro-technical interventions in the cultivation of wheat and barley and the impact of weather conditions on yields. In general, yields for both analyzed crops in both years were fairly stable. Proper implementation of agrotechnics, plant protection and correct selection of varieties made this production especially successful. Vegetation season 2017/2018 was characterized by more precipitation and higher air temperatures compared to the multi-year average. On the other hand, 2018/2019 was characterized by less precipitation than the multi-year average and higher air temperature by 0.7 °C. Under these conditions, wheat yields were 6.7 t/ha and 6.5 t/ha, and barley 6.8 t/ha and 7.6 t/ha in 2017/2018 and 2018/2019. Having seen that the production of wheat and barley have proven successful, both crops have the opportunity and growth capacity for continued production in the coming years on the family farm.

Cilj završnog rada bio je analizirati proizvodnju kukuruza na OPG-u Marko Lešić u posljednjem trogodišnjem razdoblju (2016.-2018.), odnosno prikazati provedene agrotehničke zahvate, vremenske prilike i ostvarene prinose. OPG Marko Lešić je osnovan 2016. u Bošnjacima u Vukovarsko-srijemskoj županiji i raspolaže s 35 ha oranica na kojima uzgaja najzastupljenije ratarske kulture. U sve tri analizirane godine prosječne temperature zraka su bile iznad višegodišnjeg prosjeka za 1,1 °C (2016.), 1,7 °C (2017.) i čak 2,8 °C (2018.). U usporedbi s višegodišnjim prosjekom 2016. i 2018. je palo 2 % i 24 % više oborina, a 2017. 18 % manje oborina. Prosječni prinos u sve tri promatrane godine je iznosio visokih 10,92 t/ha. Najprinosnija godina je bila 2018. s ostvarenim prosječnim prinosom od 14,5 t/ha, a najniži prosječni prinos je ostvaren 2017. godine s vrlo niskih 6,5 t/ha. U promatranom trogodišnjem razdoblju pokazalo se da kukuruz ostvaruje dosta niže prinose kada je nedovoljna količina oborina i iznadprosječna temperatura zraka što je i za očekivati. Isto tako se pokazalo da je svaka proizvodna godina specifična sama po sebi, a uz istu gnojidbu, zaštitu i sklop najveći utjecaj na prinose kukuruza imali su vremenski uvjeti., The aim of the final work was to analyse the production of maize on family farm Marko Lešić in the last three years period (2016-2018) and to show proven agrotechnical operations, weather conditions and yields. Family farm Marko Lešić was founded 2016 in Bošnjaci in Vukovar-Srijem County and has 35 hectares where they cultivate the most abundant field crops. In all three analysed years the average air temperature was higher compared to the long term mean for 1.1 °C (2016), 1.7 ° C (2017) and even 2.8 °C (2018). Compared to the long term mean 2016 and 2018 achieved 2% and 24% more precipitation, while 2017 was 18% less precipitation. Average yield in all three observed years was 10.92 t ha-1. The most prominent year was 2018 with an average yield of 14.5 t ha-1, while the lowest average yield achieved in 2017 with only 6.5 t ha-1. In the observed three years period of maize yielded a fairly low yield when insufficient precipitation and above the temperature were higher then expected. It also appeared that each production year was specific in itself, with the same fertilization, protection and the most important influence on maize yields had time conditions.

The sunflower seed yield produced during 2018. was 3 t/ha and is satisfactory considering weather conditions in the same year.

U ovom radu opisivana je tehnologija uzgoja kukuruza na OPG-u „Ivan Barišić-Jaman“ u 2018. godini. Agrotehničke mjere od same obrade tla do žetve obavljene se prema pravilima struke. Usjev kukuruza je dao odgovarajući sklop biljaka i zadovoljavajući prinos (oko 12 t/ha) s obzirom kakva je vremenska prognoza pratila 2018. godinu. Prinos silaže bio je 55 t/ha nakon čega je pohranjena u posebne silose te pokrivena folijom kako bi se spriječilo kvarenje silaže. U radu su korišteni podaci Državnog hidrometeorološkog zavoda o vremenskim prilikama za meteorološku postaju Osijek.Potreba za vodom povećava se kako biljka raste, a najveću potrebu za vodom ima u vrijeme metličanja i svilanja, za vrijeme oplodnje i početak nalijevanja zrna. Od klijanja do fiziološke zriobe kukuruza, proizvodnja kukuruza je složen proces, a brzina i trajanje svake faze ovise o karakteristikama hibrida i dužini vegetacije pojedinih hibrida kukuruza., This paper describes the technology of corn production at OPG "Ivan Barišić-Jaman" in 2018. Agrochemical measures of the soil tillage to harvest have been made according to the rules of the profession. The corn had a suitable set of plants and satisfactory yields with considering to the 2018 weather forecast. The yield of silage was 55 t / ha, after which it was stored in special silos and covered with foil to prevent the silage spoilage.The data of the State Hydrometerological Institute on weather conditions for the metrology station Osijek were used in this paper. The need for water increases as the plant grows, and the biggestt need for water is in time of tasseling and silky, during fertilization and grain filling. From germinating to physiological production is a complex process, the speed and duration of each stage depend on the hybrid characteristics and the length of the crops of some corn hybrids.

U ovom radu analizirana je tehnologija proizvodnje soje na OPG-u „Ivan Barišić-Jaman“ u 2018. godini. Agrotehničke mjere od obrade tla do same žetve usjeva obavljene su u skladu s pravilima struke. Usjev soje s obzirom na vremensku prognozu koja je pratila 2018. godinu dala je zadovoljavajući sklop kao i prinos od 4 t/ha. U radu su korišteni podaci Državnog hidrometeorološkog zavoda o vremenskim prilikama za meteorološku postaju Osijek. Vidljivo je da je 2018. godina bila suprotna u odnosu na višegodišnji prosjek. Manjak oborina, odnosno sušni period tijekom travnja i svibnja što je uzrokovalo neznačajne probleme u bubrenju, klijanju i nicanju soje, povećanje oborina tijekom lipnja i srpnja koje je uzrokovalo zadržavanje vode u usjevu. Također, manjak oborina zabilježen je u kolovozu i rujnu koje je donekle stabilizirala vlaga koja je bila dostupna od prethodna dva mjeseca., This paper analyzes soybean technology on OPG Ivan Barišić-Jaman in 2018. Agrotechnical measures from soil till harvest crops have been made according to the rules of the profession. The soybean yield due to the weather forecast that followed 2018 gave a satisfactory circuit as well as a yield of 4 t / ha. The data of the State Hydrometerological Institute on weather conditions for the metrology station Osijek were used in this paper. It is noticeable that 2018 was the year against the multi-annual average. The precipitation shortage, the drying season during April and May, caused unimaginable problems in swelling, germination and soaking of soy, an increase in precipitation during June and July that caused water retention in the crop. Also, the precipitation was recorded in August and September which somewhat stabilized the moisture that was available from the previous two months.

Kukuruz je biljka od iznimne važnosti kako u prehrani ljudi i životinja, tako i u industriji. Zrno je osnovna sirovina u proizvodnji stočne hrane zbog visokog sadržaja ugljikohidrata (70-75%), te sadržaja bjelančevina (10%). Isto tako to je jedna od najzastupljenijih žitarica na svjetskim oranicama. Kao kultura ima dosta visoke potrebe za vlagom, temperaturom i svjetlošću. U ovom je radu analizirana proizvodnja kukuruza na ̋OPG Darko Duvnjak ̋ za 2018. godinu. ̋OPG Darko Duvnjak ̋ bavi se isključivo uzgojem ratarskih kultura, a od ukupno 215 ha obradivog tla kukuruz se sije na 130 hektara. Agrotehničke mjere od same obrade tla do žetve obavljene su prema pravilima struke. Usjev kukuruza je dao odgovarajući sklop biljaka i zadovoljavajući prinos (oko 12-15 t/ha)., Corn is a plant of great importance both in the diet of humans and animals as well as in the industry. Grain is the main raw material for the production of animal feed due to high carbohydrate content (70-75%) and protein content (10%). It is also one of the most abundant grains in the world. As the culture has a lot of high demands for moisture, temperature and light. This paper analyzes the production of maize on "OPG Darko Duvnjak" for 2018. OPG Darko Duvnjak "deals exclusively with the cultivation of field crops, and from a total of 215 hectares of arable land corn is sown on 130 hectares.

Cilj završnog rada bio je prikazati detaljnu proizvodnju ječma u Republici Hrvatskoj s kratkim osvrtom i na proizvodnju u svijetu. Osim toga, u radu su opisani i agroekološki uvjeti proizvodnje ječma te uobičajena agotehnika u intezivnoj proizvodnji na našem područiju. Ječam se koristi za hranidbu životinja, industrijsku preradu te prehranu ljudi. U pogledu agroekoloških uvjeta ječam najbolje podnosi sušu i visoke temperature, ima najmanje potrebe za vodom i slabije podnosi niske temperature od pšenice. Kako bi se dobio visok i stabilan prinos vrlo su bitne sve agrotehničke mjere u proizvodnji ječam (plodored, obrada tla, sjetva, njega i žetva), a naročitu pozornost treba posvetiti gnojidbi. Među žitaricama ječam se u svijetu nalazi na četvrtom mjestu. U prosjeku se uzgaja na oko 50 milijuna ha s prosječnim prinosom od 2,9 t/ha od čega se čak 62 % zasijanih površina nalazi u Europi. U Republici Hrvatskoj ječam se u prosjeku (2006. - 2015.) uzgajao na 54 468 ha što znači da se po zastupljenosti na oranicama nalazi na četvrtom mjestu. Prosječan prinos je iznosio 3,9 t/ha što je značajno više u usporedbi s svjetskim prosjekom. Međutim, u analiziranom razdoblju prinos je varirao od 3,3 t/ha u 2010. do čak 4,4 t/ha u 2015. što je povećanje od oko 33 %, a glavni razlog ovakvih variranja su vremenske prilike., The aim of this study was to analyze barely production in Republic of Croatia with review on world production. Furthermore, the paper describes the agroecological condition of barley production and the usual practice for barley intensive production. Barley is used for animal feed, industrial processing and human nutrition. Regarding the agroecological conditions, barley is best tolerated by drought and high temperatures, it has the lowest water requirements and is quite susceptible to low temperature than wheat. All agrotechnical measures is very important for high and stabile yield of barley and fertilization is particularly important. Among the cereals, the barley is ranged in the fourth place in the world. It occupies about 50 million hectares with an average grain yield of 2.9 t/ha. In Europe there is about 62% of total barley productions. In the period from 2006 to 2015 in Croatia barley on average occupies 54 468 ha, which means that it is ranked fourth on the Croatia’s arable land The average yield was 3.9 t/ha what is notably higher in comparison to the world average. However, in that period yield varied from 3.3 t/ha in 2010 to 4.4 t/ha in 2015 what is 33% higher. Main reason for shuch high variation can be weather conditions.

Cilj rada je bio prikazati analizu provedene agrotehnike na OPG-u Milinković i vremenskih prilika na prinose ratarskih kultura tijekom dvije vegetacijske sezone. OPG Milinković je osnovano 2002. na području općine Trpinja, Vukovarsko-srijemska županija, a raspolaže sa 111 ha obradivih površina na kojima uzgaja pšenicu, ječam, kukuruz, soju i suncokret. Sva agrotehnika se obavlja pomoću vlastitih strojeva i uređaja. Obje godine sa stajališta vremenskih prilika i uzgoja ratarskih kultura su bile uglavnom povoljne jer su vrijednosti količine oborina i prosječnih temperatura zraka bile na razini ili nešto ispod višegodišnjeg prosjeka. Tijekom analiziranih godina OPG je provodio gotovo jednaku agrotehniku proizvodnje ratarskih usjeva poštujući pravila plodoreda, obrade tla, gnojidbe, zaštite od korova, bolest i štetnika te berbe ili žetve. U sjetvi se koristi uvijek certificirano i provjereno sjeme sorti ili hibrida. U 2015./2016. prinosi pšenice su bili 4,6 t/ha i ječma 5,1 t/ha dok su u 2016./2017. prinosi pšenice bile nešto veći (5,2 t/ha). U obje godine uzgoja kukuruz je postigao najveće prinose od 9,5 t/ha (2016.) i 8,6 t/ha (2017.). Suncokret je u prosjeku obje godine ostvario prinos od oko 4,0 t/ha, dok je prinos soje varirao od 2,4 t/ha (2017.) do 2,9 t/ha (2016.). Ostvareni prinosi analiziranih kultura su bili zadovoljavajući s obzirom na provedenu agrotehniku i vremenske prilike., Aim of this final work was to shown conducted agrotechnic operations on family farm Milinkovic and influence of weather conditions on yield filed crops during two vegetation season. Family farm Milinkovic was established 2002 in Trpinja, Vukovarsko-srijemska county. They has 111 ha arable land on which cultivated wheat, barley, maize, soybean and sunflower. Family farm Milinkovic owns all technical equipment for agrotehnical operations. Both years with aspect of field crops and weather conditions were mostly favorable. Values of total precipitation and average air temperatures was on level of long term mean or little below them. During analyzed years family farm did almost equal agrotehnich operations with aspect of crop rotation, soil tillage, fertilization, weed, insect and disease protect and harvest. In sowing, they always used certified seeds of varieties and hybrids. In vegetation 2015/2016 wheat yield was 4.6 t ha-1 and barley 5.1 t ha-1 while wheat yield in 2016/2017 was bigger (5.2 t ha-1 ). In both year maize achieved the highest yield from 9.5 t ha-1 (2016) to 8.6 t ha-1 (2017). Sunflower was in average for both years achieved 4.0 t ha-1 while soybean yield varied from 2.4 t ha-1 (2017) to 2.9 t ha-1 (2016). Generally, achieved yields tested field crops was satisfactory with aspect of conducted agrotechnics operations and weather conditions.

Raž (lat. Secale cereale) je jednogodišnja biljna vrsta iz porodice trava (Poaceae, Gramineae) koja se kao žitarica najviše uzgaja u sjevernoj Europi, a uspijeva do 69.5° sjeverne širine. Ciljevi uzgoja raži slični su onima u uzgoju drugih žitarica maloga zrna. Raženo zrno se koristi uglavnom za hranu, ali i za proizvodnju etanola. Ova žitarica je druga u nizu, nakon pšenice, za proizvodnju kruha, a koristi se i kao pašnjak ili krmno bilje. Također, služi i kao zimski pokrovni usjev jer raste brzo u jesen te pokriva zemlju i tako štiti tlo od erozije. Ova žitarica je posebno važan usjev u Poljskoj, Njemačkoj, Rusiji, Ukrajini i Bjelorusiji. U Hrvatskoj se uzgaja u mnogo manjim količinama. Iako je raž je najzahvalnija i najskromnija žitarica prema klimatskim uvjetima i tlu, kultivirana površina raži i njezina proizvodnja u svijetu znatno se smanjila u posljednjih pola stoljeća. Raž se danas uglavnom proizvodi za industrijske potrebe tržišta, međutim, to su zaista ukupno gledajući male površine., Rye (lat. Secale cereale) is a one-year plant species and a member of the wheat tribe (Poaceae, Gramineae) which is mostly bred as a cereal in northern Europe and it is succesfully bred to 69,5° of the nothern latitude. Goals in rye breeding are similar to those of other small grain cereals. Rye grain is mostly used for food but also for ethanol production. This cereal is, after wheat, the second most used cereal in bread production and it is also used for pasture or roughage. It also serves as a cover crop beacuse it grows fast in the autumn and in that way covers the land and protects it from the erosion. This cereal is very important in Poland, Germany, Russia, Ukraine and Belarus. It is also bred in Croatia, but in smaller amount. Although rye is the most thankful and the humblest cereal to breed judging by climate and soil condition needed, cultivated surface of rye and it's production have been significally reduced in last half of the century. Rye is today mostly used for industrial needs of the market, however those amounts are in total view very small amounts.

U radu su se ispitivali utjecaji vremenskih prilika i agrotehnike na činitelje prinosa i kvalitete zrna soje 2017. godine na gospodarstvu OPG „Primorac Željko“. Podaci za vremenske prilike u istraživanju korišteni su sa Državnog hidrometeorološkog zavoda meteorološke postaje Osijek 2017. godine u razdoblju od mjeseca travnja do rujna. U vegetaciji soje zabilježeno je 2017. godine 319,9 mm, odnosno manje za 57,9 mm u odnosu na višegodišnji prosjek (377,8 mm), a srednja temperatura iznosila je 19,1 °C, odnosno bila je veća za 1,3 °C od višegodišnjeg prosjeka (17,8 °C). Agrotehnički zahvati na gospodarstvu 2017. godine obavljani su po preporuci stručne literature i dosadašnjih istraživanja, ali i vlastitih iskustava u proizvodnji soje. Ostvareni prosječni prinos na gospodarstvu 2017. godine je 4,9 t/ha. Po podacima o vremenskim prilikama i ostvarenom prosječnom prinosu može se zaključiti da je prinos visok iako je 2017. godina bila sušna., The paper analyzes the effects of weather and agrotehnics on yield and quality of soybean grain on family farm „Primorac Željko“ in 2017. Weather data used in the study was taken from Hydrometeorological Institute in Osijek in the period from April to September 2017. The average rainfall in soybean vegetation in 2017 was 319.9 mm, which is 57.9 mm less than the annual average (377.8 mm). The average temperature was 19.1 °C, which is 1.3 °C higher than the average perennial (17.8 °C). Field work on the farm was done according to previous researches, contemporary literature and previous on field experiences in soy production. The average yield on the farm in 2017 was 4.9 t/ha. It can be concluded that the yield was high although the year was predominantly dry.

Cilj završnog rada bio je prikazati analizu provedene agrotehnike i postignute prinose pšenice na obrtu PRO FARM Mandić tijekom dvije vegetacijske godine 2016./2017. i 2017./2018. U strukturi sjetve na obrtu dominira proizvodnja pšenice i uljane repice, a posjeduje svu potrebnu mehanizaciju za intezivnu ratarsku proizvodnju. Obje analizirane godine karakterizira iznadprosječna temperatura zraka dok je u pogledu količine oborina 2016./17. bila s manje oborina, a 2017./18. s više oborina uz relativno nepovoljnu distribuciju. Tijekom analiziranih godina PRO FARM Mandić je provodio gotovo istu intenzivnu agrotehniku uz naglasak na poštivanje plodoreda. Tijekom vegetacije obavljene su sve potrebne mjere njege i zaštite od korova, bolesti i štetnika prema potrebi u svakoj analiziranoj godini. U vegetaciji 2016./2017. prosječan prinos sa svih površina je iznosio 8,2 t/ha, dok je u 2017./2018. iznosio nešto manje (7,5 t/ha). S obzirom da su agrotehničke operacije bile vrlo slične za obje godine glavni razlozi niţih prinosa u 2018. mogu biti nešto lošiji vremenski uvjeti uz neravnomjernu distribuciju oborina tijekom vegetacije., The purpose of this final work is to present analysis of agrotechnics and yield of wheat at the family farm PRO FARM Mandić during two vegetative seasons 2016/2017 and 2017/2018. Wheat and rapeseed dominate the planting structure, whereas the farm owns all mechanization needed for intensive agriculture production. Both analyzed years were characterized by above the average air temperature and rainfall fluctuations, with less than average rain during 2016/2017 and above the average rain during 2017/2018 with unfavorable distribution of rainfalls. During two analyzed years PRO FARM Mandić carried same intensive agrotechnical operations respecting crop rotation. During the period of vegetation, fertilization, weed, diseases and pests control measures were carried as needed. Average yield was 8.2 t ha-1 and 7.5 t ha-1 in 2016/2017 and 2017/2018, respectively. Agrotechnical measures were similar in both years, main reason for smaller yield in 2018 was due to less favorable weather condition and fluctuation of rainfall during vegetative period.

Ječam ima veliku važnost u industriji piva i viskija jer se od njega dobiva kvalitetan slad kojim se postiže jačina i kakvoća proizvoda. Također ima veliku agrotehničku važnost jer se ranije sije i ranije dozrijeva. U ovom radu objašnjeno je kakve uvjete uzgoja ječam zahtjeva, te što je sve potrebno da bi taj ječam bio pivarski. Skromnih je zahtjeva prema vlazi i toplini u odnosu na pšenicu. . Na nedostatak vode najosjetljiviji je u vrijeme nalijevanja zrna. Mora se uzgajati na plodnijim tlima. Provođenjem svih agrotehničkih mjera može se očekivati prinos 5 i više t ha-1. Osim agrotehnike i uvjeta uzgoja u rad je uvršten rad naših selekcijskih kuća i njihove sorte. Dugotrajnim i napornim radom stvaraju se kvalitetne sorte koje zadovoljavaju sve parametre uzgoja., Barley is a grain of great importance concerning the industries of beer and whiskeys since it produces a high-quality malt. Malt is the ingredient that guarantees the strength and quality of the products. Barley is also of a great agrotechnical significance because it is known as a grain which soars and matures earlier than most of other species. This paper explains the conditions in which the barley is grown and describes the requirements needed to make that barley a brewery ingredient. Barley doesn’t require as much heat and moisture in comparison to wheat. It is most sensitive to the lack of water at the time of grafting. It is necessary for barley to be planted and grown on more fertile soil. By performing all necessary agrotechnical measures, the income of 5 and more t ha-1 can be anticipated. In addition to the agrotechnology and the conditions of breeding, this work also describes the work of our selection houses and their grain sorts. Longlasting and hard work can produce the high-quality sorts which meet all the parameters of growth.

Osnovni cilj rada bila je analiza proizvodnje odnosno provedene agrotehnike kukuruza na PG Grube d.o.o. tijekom dva vegetacijska razdoblja 2016 i 2017. Poljoprivredno gospodarstvo obrađuje oko 350 ha oranica na kojima dominira proizvodnja kukuruza, a bavi se i stočarskom proizvodnjom. Analizirane godine su bile drugačije sa stajališta uzgoja kukuruza jer je u 2016. bilo više, a 2017. manje oborina od promatranog prosjeka (1981.-2016.). Istovremeno, temperature zraka su bile više u obje godine. S obzirom da PG Grube posjeduje vrlo velik broj suvremene mehanizacije sve agrotehničke operacije su provedene u skladu s pravilima struke ukoliko su to vremenske prilike dozvoljavale. Sjetva kukuruza se obavila na gustoću sklopa od 64 000 do 69 000 biljaka po ha, a posijani su hibridi sjemenskih kuća Bc Instituta Zagreb i KWS. S obzirom da je kukuruz širokoredni usjev posebna pozornost se posvetila zaštiti protiv korova. Na PG Grube ostvareni prinosi kukuruza su jako ovisili o vremenskim prilikama tijekom vegetacije, ali općenito bili su iznadprosječni u usporedbi s državnim prosjekom. Ostvareni prinosi u 2016. su se kretali od 11,9 t/ha do 15,6 t/ha, a u 2017. su iznosili od 6,8 t/ha do 12,5 t/ha., The main aim of the work was to analyse the production of the maize and agrotechnics at PG Grube d.o.o. during the two vegetation periods 2016 and 2017. On this farm about 350 hectares is cultivated and maize production dominates, but is also engaged in livestock production. The analysed years were different from the standpoint of maize growing because in 2016 there were more, and in 2017 was less precipitation than the observed average (1981-2016). At the same time, air temperatures were higher in both years. As PG Grube possesses a very large number of modern mechanics, all agrotechnical operations have been carried out in accordance with the rules of the profession, if permitted by weather conditions. Maize sowing was done on a density of 64,000 to 69,000 plants per ha, and maize hybrids of Bc Institute Zagreb and KWS were sown. Special attention has been paid to the protection against weeds. Maize yields on PG Grube were highly dependent on weather conditions during vegetation but overall were above average compared to the state average. The realized yields in 2016 ranged from 11.9 t/ha to 15.6 t/ha, and in 2017 from 6.8 t/ha to 12.5 t/ha.

Cilj diplomskog rada je bila analiza proizvodnje ozime pšenice na poljoprivrednom gospodarstvu TID Solara tijekom tri vegetacijske godine (2014./2015, 2015./2016. i 2016./2017.) s obzirom na vremenske prilike i provedenu agrotehniku. Vremenske prilike su bile specifične za svaku godinu. Količina oborina tijekom 2014./2015. godine nije značajnije odstupala od višegodišnjeg prosjeka uz povećanu prosječnu temperaturu zraka za 1,4 °C. Iako nije bilo drastičnih odstupanja u ovoj vegetaciji su ostvareni najniži prosječni prinosi pšenice od 7,63 t/ha. Sorta Kraljica je imala veći prinos i bolju kvalitetu u usporedbi sa sortom BcMira. Tijekom 2015./2016. godine vremenske prilike su bile gotovo jednake prethodnoj godini, ali uz značajna odstupanja tijekom mjeseci. Tako je prevelika količina oborina u listopadu odgodila sjetvu, a tijekom lipnja i srpnja i žetvu. Prosječno ostvareni prinosi su bili 8,26 t/ha uz relativno dobru kvalitetu zrna u pogledu sadržaja proteina (13,5 %) i hektolitarske mase (82,0 kg/hl). Sorta Sofru je imala nešto niži prinos i manji sadržaj proteina od sorte Falado. U 2016./2017. godini količina oborina je bila niža za 11% u usporedbi s višegodišnjim prosjekom dok je temperatura zraka bila na razini višegodišnjeg prosjeka. Takvi uvjeti su izuzetno pogodovali razvoju ozime pšenice jer su u ovoj godini postignuti najviši prinosi i kvaliteta zrna. Sorta Sofru je postigla prinos od 10,12 t/ha uz izuzetno visok sadržaj proteina (14,0 %) i hektolitarske mase (84,3 kg/hl) dok je sorta Falado postigla 10,05 t/ha i nešto slabiju kvalitetu. Visoki prinosi i kvaliteta tijekom analiziranog razdoblja su opravdali sva ulaganja kroz agrotehničke operacije te se proizvodnja kao takva pokazala ekonomski isplativa., The aim of this graduate thesis was to analyze the production of winter wheat in the agricultural holding of TID Solara during the three vegetation seasons (2014/2015, 2015/2016 and 2016/2017) with respect to weather conditions and conducted crop management. The weather conditions were specific for each year. Rainfall in 2014/2015 season did not significantly deviate from the annual average with an increased average air temperature of 1.4°C. Although there were no drastic deviations in this vegetation, the lowest average yields of wheat of 7, 63 t/ha were achieved. The Kraljica variety had a higher grain yield and better quality compared to BcMira. During 2015/2016 weather conditions were almost the same as in the previous season, but with significant deviations over the months. High precipitation rate in the late October and also during June and July postponed sowing, as well as harvest. The average yield were 8, 26 t/ha with relatively adequate grain quality in terms of protein content (13.5%) and hectoliter weight (82.0 kg/hl). Sofru variety had a slightly lower yield and lower protein content than Falado's. In 2016/2017 rainfall was lower by 11% compared to the annual average, while the air temperature was on a multi-year basis. Such conditions were extremely favorable to the development of winter wheat because the highest yield and grain quality were achieved this year. Sofru varitey achieved a yield of 10.12 t/ha with very high protein content (14.0%) and hectoliter weight (84.3 kg/ hl) while Falado varieties reached 10.05 t/ha and slightly lower quality. High yields and quality throughout the analyzed period justified all investments through agronomic practice and production as such proved to be economically viable.

Obiteljsko poljoprivredno gospodarstvo Solaković osnovano je 2000. u mjestu Bapska u Vukovarskojsrijemskoj županiji. Bavi se ratarskom i stočarskom proizvodnjom. Cilj rada bio je analizirati provedene agrotehničke mjere u proizvodnji pšenice te utvrditi utjecaj vremenskih uvjeta tijekom dvije vegetacijske godine (2015./2016. i 2016./2017.) na prinos i kvalitetu zrna ozime pšenice. Količina oborina u prvoj analiziranoj godini je bila vrlo slična višegodišnjem prosjeku (480 mm) dok je temperatura zraka bila viša za 1,2 °C u usporedbi s višegodišnjim prosjekom (9,2 °C). U 2016./2017. godini ukupno je palo manje oborina za 17 % uz sličnu vrijednost temperature zraka. U obje godine na OPG-u je obavljena vrlo slična agrotehnika. Oranje je obavljeno na 25 cm dubine, a predsjetvena priprema tanjuračom. U osnovnoj gnojidbi se primijenilo 250 kg/ha NPK 15-15-15 i 50 kg/ha ureje, a preostale količine dušika su dodane u dvije prihrane KAN-om u količini 200 kg/ha i 150 kg/ha. U obje godine je sijana sorta Lucija u optimalnom agrotehničkom roku. Prosječan prinos u vegetaciji 2015./2016. je iznosio 6,4 t/ha uz viši postotak proteina (12,6%) i veću hektolitarsku masu (83,2 kg/hl). U sljedećoj vegetaciji prosječan prinos je bio nešto veći (6,6 t/ha), ali s nižim sadržajem proteina (11,3%) i manjom hektolitarskom masom (82,7 kg/hl)., The family farm Solakovic was established in 2000 in Bapska, Osijek-Baranya County and they have crops and livestock production. The aim of this work was to analyze the agrotechnical measures in winter wheat production and to determine the influence of weather conditions during the two vegetation seasons 2015/2016 and 2016/2017 on grain yield and quality of wheat grain. The amount of precipitation in the first year was very similar to the long term mean (480 mm) while air temperature was for 1.2 °C higher in comparison to the long term mean (9.2 °C). In the 2016/2017 season amount of precipitation was 17% less in comparison to the long term mean while air temperature was similar to the long term mean. In the both years similar agrotechnics were made. Ploughing was on the 25 cm depth while seedbed preparation was made with harrows. Basic fertilization was done with NPK 15-15-15 in amount of 250 kg/ha and urea in amount of 50 kg/ha. Topdressing was made twice with KAN in amount of 200 kg/ha and 150 kg/ha. In both years winter wheat variety Lucija was sown in an optimal agrotechnical term. Average wheat yield in 2015/2017 was 6.4 t/ha with higher protein content (12.6%) and higher hectolitre weight (83.2 kg/hl). In the next year average yield was slightly higher (6.6 t/ha) but with the lower amount of protein content (11.3%) and lower hectolitre weight (82.7 kg/ha).

U ovome radu je opisan utjecaj vremenskih uvjeta na proizvodnju ječma na OPG-u Ivica Živković u 2014. i 2015. godini. Opisana je agrotenika proizvodnje ječam koja je u obe godine bila identična i uz podateke Državnog hidrometeorološkog zavoda o vremenskim prilika u 2014. i 2015. godini za postaju Đakovo donešeni su zaključci o utjecaju vremneskih uvjeta na proizvodnja ječama. U 2014. godini prosječan prinos je bio 4,1 t/ha, a u 2015. godini prosječan prinos je bio 5,3 t/ha. Iz čega je vidljivo da vremenski uvjeti imaju velik utjecaj na prinos ječam. Prosječna temperatura u obe godine bila je 12,9 ˚C što je za 1,5 ˚C više od višegodišnjeg prosjeka. Oborine su u 2014. godini bile izdad prosječne, za razliku od 2015. godine kada su bile ispod višegodišnjeg prosjeka., This seminar describes the influence of weather conditions on barley production at family farm Ivica Živković in 2014. and 2015. year. The barley productions agronomy is described in 2014. and 2015, which was identical. Analyzing The Data Of the State Hydrometeorological Institute on weather conditions in 2014. and 2015. for Đakovo station, conclusions weremade on the influence of weather conditions on barley production. In 2014. The average contribution was 4,1 tonnes of hectares, indian 2015. Average Contribution Was 5,3 tonnes of hectares. Wecanconcludethatthe Contribution Of barley depends on weather influences. The average temperature in both years was 12,9 ˚C, which is 1,5 ˚C more than a yearly average. Precipitation rates were up on average in 2014, as opposed to 2015 when they were below the perennial average.
