Serbia has favorable natural conditions for the development of livestock production, especially the cow's milk production. Average milk production is 1.5 billion liters per year and the dominant share is produced on small farms. Only 35.1% of the total amount of milk produced in Serbia is processed. The subject of this research are economic aspects of milk production and processing into skimmed cream and white cheese on family farms. For that purpose, the model for the production of traditional milk products on family farms was developed and analysed, by using the method of analytical calculation based on variable costs. The results have shown that the difference between the production price per liter of raw vs. processed milk was € 0.24, while between the selling price of raw and processed milk per liter was € 1. Farms with up to 15 dairy heads should consider milk processing, i.e. finalization of products.

- Abstract
Plastic has been recognized as one of the leading pollutants of all ecosystems. This question has been rarely raised in Serbia, although there is a significant problem with the disposal of communal and agricultural waste. Many wild landfills have been created in past decades in forests near the plasticulture practicing areas and rivers. Plastic materials are degraded by the influence of UV light and various environmental factors, creating smaller particles called microplastics, which are recognized as significantly dangerous to ecosystems. Alluvial planes have been the most endangered due to the horizontal and vertical fluvial activities of the nearby rivers. The influence of soil microplastics on insect communities has not been widely considered and that is why the project EMIPLAST-SoS has been created to investigate insect communities in polluted and unpolluted alluvial soils in Serbia. We compare them in forest and agricultural ecosystems on similar alluvial soils in three locations near three largest rivers in Serbia. Preliminary results from one-season sampling are considered. During the project the influence of the different seasons effects will be investigated. Additionally, we have investigated the rate of plastic decomposition by five insect species in lab conditions (Plodia interpunctella Hubner, Tenebrio molitor L., Zophobas morio Fabr., Achroia grisella Fabr. and Galleria mellonela L.). G. mellonela expressed the highest and the most diverse decomposition of different plastic sources like plastic bags, sponges and styrofoam. The analyses of the obtained plastic residues are still underway.

- Abstract
Gastrointestinal nematodes represent parasites of great importance in veterinary medicine, especially in grazing animals such as small ruminants. In most cases, these parasites cause subclinical diseases with losses in body weight, reduced feed intake and decreased production. However, high worm burdens may lead to severe clinical signs such as anorexia, anaemia, diarrhoea, protein loss, oedema, decreased immunity and fertility, which can lead to fatal outcomes. Therefore, gastrointestinal nematodes hinder sheep farming in different ways leading to high economic losses that are estimated at several hundred million euros in Europe, although it is difficult to quantify it precisely. An additional problem is the development of anthelmintic resistance in nematodes that occur as a result of irrational use of commercial drugs, whereby the main risk factors are overfrequent treatments, underdosing, the use of only one drug without combination or rotation etc. This leads to a decrease in their effectiveness, and consequently to even higher economic losses (an additional 35-40 million euros). Moreover, these costs will tend to increase in the future due to widespread of resistance and the occurrence of multiresistant strains. For these reasons, the focus of nowadays research is finding alternative solutions including genetic selection of naturally resistant animals, pasture management, dietary manipulation, biological control (use of nematophagous fungi, bacteria or earthworms and dung beetles) and the use of plant-based formulations such as extracts and essential oils. All of the above strategies have shown promise, although it appears that none of them could be used independently. Therefore, future strategies for the control of gastrointestinal nematodes should be based on an integrated approach. This implies the combination of mentioned alternatives with rational use of anthelmintics based on refugia strategies (target treatments and target selective treatments).

Četvorogodišnji mikroogledi su postavljeni 2015. godine iizvedeni na poljoprivrednim površinama sela Petkovica (opština Šabac). Predmet istraţivanja bila je domaća sorta pasulja Sremac, koja je sejana u prolećnom roku, a u 2018. godini i postrno. Proizvodnja je organizovana na vrlo siromašnom zemljištu teškog mehaničkog sastava sa preovlaĎujućom fizičkom glinom (oko 68%) pa je uz mineralna NPK hraniva korišćena i organska biomasa (kompost i saturacioni mulj). Pasulj je gajen na većim površinama uz primenu standardne tehnologije proizvodnje, a posle setve obeleţavane su eksperimentalne parcele. Tokom izvoĎenja ogleda detaljno su analizirani osnovni meteorološki podaci vodni reţim i raspored toplote u vegetacionom periodu pasulja. Prva i treća godina bile su sa značajno manjim količinama padavina u periodu april-septembar i sa dugim sušnim periodima tokom leta, dok su druga i četvrta godina imale vrlo povoljan reţim padavina. Varijabilnost vremenskih uslova značajno je uticala na visinu ostvarenih prinosa, a u četvrtoj godini omogućila i uspešnu postrnu setvu (Vasić i sar., 2007). Osnovni cilj istraţivanja bio je da se utvrdi koliki prinos zrna se moţe ostvariti sortom koja je tolerantna na sušu i podesna za gajenje u suvom ratarenju. Na osnovu ostvarenih prinosa, obračunatih materijalnih troškova i angaţovanja mehanizacije, odreĎeno je procentualno učešće varijabilnih troškova proizvodnje u ceni proizvoda. Dobijene vrednosti mogu posluţiti kao preporuka malim farmerima kako uz najpodesnije agrotehničke metode mogu ostvariti što veći bruto finansijski rezultat u proizvodnji pasulja. The four-year field trials were set in 2015 and carried out on agricultural surfaces of the village village Petkovic (municipality Sabac). The subject of the research was beans, domestic variety Sremac, which was sown in the spring, and in 2018, as stubble crop. Beans are grown on a very poor soil with a heavy mechanical composition with a predominant physical clay (about 68%). Therefore, organic (compost and saturated sludge) and NPK mineral fertilizers are used in the nutrition of plants. The beans are grown on large plots with the application of standard production technology. Experimental plots were marked after sowing. During the experiment, the detailed meteorological data were analyzed in detail by the water regime and the distribution of heat in the vegetation period of the bean. Basic meteorological data (water regime, and heat distribution) were analyzed during the vegetation period of beans. The first and third years were with significantly smaller amounts of precipitation in the period April-Septemberand with long drought periods during the summer, while the second and fourth years had a very favorable precipitation regime. Variability of weather conditions significantly influenced the amount of yields achieved, and in the fourth year enabled successful stubble sowing (Vasić et al., 2007). The basic aim of the research was to determine the extent of grain yield can be achieved by a drought tolerant variety and suitable for growing in dry cropping system. On the basis of realized yields, calculated material costs and engagement of mechanization, the percentage participation of variable production determined is costs in the price of the product. The values obtained can be used as a recommendation to small farmers to achieve the highest gross financial result in the production of beans with the most suitable scientific farming methods.

Environmental conditions significantly influence agricultural production, i.e. they are one of the main factors that affect its efficiency. Continuous monitoring of economic results makes it possible to identify the basic elements of revenues and expenditures in production of major agricultural crops, and use these data to plan future production – in other words, to choose the right enterprise for respective environmental conditions. The gross margin is a quick and efficient indicator used to analyse an enterprise when considering economic indicators of different enterprises and choosing the most efficient one in economic terms. In this paper we used the gross margin to compare the two production years with different production conditions, but on the same farms. Therefore, gross margin was used as an adequate indicator that aims to show the difference which is in function of various agro-ecological conditions, price and yield within the period of two years. The paper used the questionnaire carried out in 2011 and 2012 on a total of 69 chosen leader farms from the territory of 11 stations of the Agricultural Extension Service of Serbia. The questionnaire collected data on revenues and expenditures based on which gross margins for maize were calculated. The main indicator of this calculation is the gross margin, which is the difference between the value of production (value of the primary and the secondary product) and total variable costs that covers seed costs, fertilizer costs, costs of plant protection products, diesel fuels and contracted services (for sowing, harvest and labour). In these periods climatic conditions differed significantly. In 2012 there was considerably less precipitation with higher air temperatures, which was one of the main reason for reduced yields per area unit. In 2012, yields decreased by 28%, while price per kilogram of maize increased by about 37%, reducing total value of production by about 1%. It was estimated that total variable costs increased by 6%, while the gross margin was reduced by about 8%.

The scope of agricultural production is to a great extent affected by volatile risks. This paper presents possibilities that financial markets provide to manage such risks. It minutely describes basic derivatives, futures and options, with a special focus on their use on agricultural commodities. The paper further describes probably the most popular futures -- weather futures. Furthermore, the authors deal with complex and cross-hedging strategies. The last section brings the analysis of possibilities of establishing a derivatives market in Serbia. The first step towards this goal is to set up a commodity market and adopt related legislation, but also to meet other preconditions, such as to establish a licensing system, simplify trade with foreign entities, establish a system of clearing, develop a framework for extra-judicial settlement and to work on internationalisation of trade. Once these preconditions are met, it would be possible to establish an agricultural commodity derivatives trading system. [ABSTRACT FROM AUTHOR]

The application of the latest information and telecommunication technologies is becoming inevitable in business development. Modern information technologies have been widely used in all stages of trading, from procuring, storing and handling goods, through selling and collection, to post-selling activities and costumer services, both in the wholesale and retail sector. Agriculture is an industry that, among others, has a large potential in the area of electronic commerce, and especially in the segment of web technology. In this paper we analysed several categories of web presentations - web sites that provide transaction cost savings, intermediaries on the electronic market, integrated services of electronic commerce and electronic commerce support service providers. We also systematised the benefits of using web technology. In the last section of this paper we gave the analysis of the current situation and potentials in the Republic of Serbia, giving an overview of introducing a new mobile phone technology for informing participants in the agricultural value chain.

CLIMATE change , *BIOLOGICAL adaptation , *TEMPERATURE , *SUSTAINABLE development - Abstract
Global warming majorly changes the environment and affects plant and animal species. Climate change is too abrupt for plants and animals to adapt easily. Plant and animal species respond to new conditions with adaptations in space and time, during which changes in phenological stages and migration take place. Over the last decade, plant and animal populations have been decreasing due to an unsynchronized response of co-dependent species to climate change. When there is a mutually-dependent relationship between species with temperature-based phenological stages and species that depend on the number of sunshine hours, a change in the temperature cycle when the cycle of sunlight remains the same can result in extinction of species. The paper shows the impact of climate change on change in phenological stages in general, and its indirect impact on yield and agriculture. The goal is to point out the need for analyzing effects of global warming in the Republic of Serbia in order to anticipate potential deviations from the expected and enable sustainable development.
