Abstract

A small-plot field experiment with sugar beet (Beta vulgaris provar. altissima Doell.) was focused on the monitoring of year weather conditions, selected genotypes and stimulating substances on the formation of quantitative and qualitative parameters. The experiment was carried out in the Center for Plant Biology and Ecology in Nitra during the years 2021 – 2022. The area is located at an altitude of 170 – 175 m above sea level in a corn production area with warm and dry climatic characteristics. The results of the experiment confirmed a statistically proven effect of the year conditions (P < 0.01) on the formation of quantitative and qualitative production parameters. In the range of monitored factors, agro-ecological conditions were more favourable in 2021, when a statistically higher root yield of 68.99 t/ha (+9.68 t/ ha; rel. 16.32%) also sugar content of 16.75% (+0.68%; rel. 4.21%) were recorded. The statistical analysis confirmed a highly significant relationship (P < 0.01) between selected varieties and quantitative or qualitative production parameters. In the range of monitored genotypes, the highest root yield was recorded by Darvas 65.83 t/ha (+1.68 t/ha; rel. 2.62%) and the highest sugar content was indicated by Okapi 16.59% (+0.18%; rel. 1.11%). Implementation of stimulating substances with adaptogens positively affects the yield and sugar content of sugar beet. Stimulating preparations statistically affect (P < 0.01) the formation of monitored production parameters. The highest root yield of 67.40 t/ha (+7.56 t/ha; rel. 12.64%) and sugar content of 16.58% (+0.47%; rel. 2,91%) was indicated by variant 2 (Energeen Cleanstorm)., Maloparcelkový poľný experiment s repou cukrovou (Beta vulgaris provar. altissima Doell.) bol zameraný na monitoring vplyvu poveternostných podmienok, vybraných genotypov a stimulačne pôsobiacich látok na tvorbu kvantitatívnych a kvalitatívnych parametrov. Pokus bol realizovaný v Stredisku biológie a ekológie rastlín v Nitre počas rokov 2021 – 2022. Oblasť je lokalizovaná v nadmorskej výške 170 – 175 m nad morom, v kukuričnej výrobnej oblasti s teplou a suchou klimatickou charakteristikou. Výsledky experimentu potvrdili štatisticky vysoko preukazný vplyv ročníka (P < 0,01) na tvorbu kvantitatívnych i kvalitatívnych parametrov. V rozsahu sledovaných faktorov boli priaznivejšie agroekologické podmienky počas roku 2021, kde bola indikovaná štatisticky vysoko preukazne vyššia úroda 68,99 t.ha-1 (+ 9,68 t.ha-1; rel. 16,32 %) aj cukornatosť 16,75 % (+ 0,68 %; rel. 4,21 %). Štatistická analýza potvrdila vysoko preukazný vzťah medzi vybranými odrodami (P < 0,01) a kvantitatívnymi i kvalitatívnymi parametrami produkcie. V rámci sledovaných genotypov bola zaznamenaná najvyššia úroda buliev pri odrode Darvas 65,83 t.ha-1 (+ 1,68 t.ha-1; rel. 2,62 %) a najvyšší obsah cukru bol indikovaný pri odrode Okapi 16,59 % (+ 0,18 %; rel. 1,11 %). Implementácia stimulačne pôsobiacich látok s adaptogénnmi pozitívne formuje tvorbu úrody a obsah cukru repy cukrovej. Stimulačne pôsobiace prípravky mali štatisticky vysoko preukazný vplyv (P < 0,01) na formovanie sledovaných parametrov produkcie. Najvyššia úroda buliev 67,40 t.ha-1 (+ 7,56 t.ha-1; rel. 12,64 %) a cukornatosť 16,58 % (+ 0,47 %; rel. 2,91 %) bola indikovaná na variante 2 (Energeen Cleanstorm).

Abstract

Sunflower (Helianthus annuus L.) is grown in Slovak growing conditions for edible oil of high quality, its composition of unsaturated fatty acids affects the human health positively. Influence of year, hybrids (Marbelia CS and Reasun DS5) and biostimulating preparations (Florone and Fertisiline) on yield, oil content, and amount of selected fatty acids (oleic, linoleic, palmitic, and stearic acids) was find out in this study. Also evaluate the relationship within the achieved yield and oil content with the obtained amount of selected fatty acids. Field small-plot experiments were established by randomized split plot method during the growing years of 2018 and 2019. The experimental field is situated in a warm maize production area, while the course of weather conditions during individual growing seasons was different. On an average for experimental period of 2018-2019, more favorable course of temperatures and precipitation was recorded in 2018. Significantly higher achene yield (3.29±0.35 t/ha) and a higher amount of selected fatty acids (oleic acid 62.11±4.33%; linoleic acid 45.32±4.62%; palmitic acid 5.26±0.33%; stearic acid 4.21±0.20%) were found in Reasun DS-5 hybrid. Both biostimulating preparations had a significant effect on the yield and oleic acid content, when both biostimulators were applied in BBCH 15 and BBCH 55. The amount of linoleic acid decreased by both biostimulating applications in BBCH 15 (Florone 33.88±10.57%; Fertilisine 34.11±13.37%) and BBCH 15, 55 ((Florone 34.08±12.34%; Fertisiline 34.26±13.40%) compared by control treatments (38.43±6.01%). The contents of linoleic acid on treated variants by both preparations in BBCH 55 (Florone 38.26±9.47%; Fertisiline 39.03±8.95%) were statistically nonsignificant with comparison to untreated control. The height of yield was negatively correlated (r= -0.310; P, Slnečnica ročná (Helianthus annuus L.) je v našich podmienkach pestovaná hlavne pre získavanie vysoko kvalitného jedlého oleja, ktorého zloženie nenasýtených mastných kyselín pozitívne vplýva na zdravie človeka. V tejto štúdii bolo cieľom zistiť vplyv ročníka, hybridov (Marbelia CS a Reasun DS-5) a biostimulačných prípravkov (Florone a Fertisiline) na úrodu, obsah oleja a množstvo vybraných mastných kyselín (kyselina olejová, linolová, palmitová a steárová). Taktiež zhodnotiť vzťah v rámci dosiahnutej úrody a obsahu oleja so získaným množstvom vybraných mastných kyselín. Poľné maloparcelové experimenty boli založené metódou kolmo delených blokov a v náhodnom usporiadaní počas pestovateľských rokov 2018 a 2019. Pokusné stanovište je situované v teplej kukuričnej výrobnej oblasti, pričom priebeh poveternostných podmienok počas jednotlivých pestovateľských období bol rozdielny. V priemere za sledované obdobie bol štatisticky preukazne vhodnejší priebeh teplôt a zrážok zaznamenaný v roku 2018. V priemere štatisticky preukazne vyššia úroda nažiek (3,29±0,35 t.ha-1) a vyšší obsah vybraných mastných kyselín (kyselina olejová 62,11±4,33 %; kyselina linolová 45,32±4,62 %; kyselina palmitová 5,26±0,33 %; kyselina steárová 4,21±0,20 %) boli zistené pri hybride Reasun DS-5. Použitím biostimulačných prípravkov bola úroda v priemere za sledované obdobie ovplyvnená štatisticky preukazne, pri aplikácii oboch prípravkov (Florone a Fertisiline) v rastovej fáze BBCH 15 aj BBCH 55 (fáza 6-8 listov a fáza kvitnutia), rovnako tak aj množstvo kyseliny olejovej. Obsah kyseliny linolovej klesol po aplikácii oboch prípravkov v rastovej fáze BBCH 15 (Florone 33,88±10,57 %; Fertilisine 34,11±13,37 %) a BBCH 15, 55 (Florone 34,08±12,34 %; Fertisiline 34,26±13,40 %) v porovnaní s kontrolným variantom (38,43±6,01 %). Obsahy získanej kyseliny linolovej na variantoch ošetrených vo fáze BBCH 55 (Florone 38,26±9,47 %; Fertisiline 39,03±8,95 %) boli štatisticky nepreukazné v porovnaní s kontrolou. Výška úrody negatívne korelovala (r= -0,310; P

Abstract

In the field experiments carried out in 2019 – 2020 on the plots of PD Špačince, the influence of agroclimatic conditions of the year on the yield of roots and sugar content of 9 varieties (Alabaster, Francessa, Jagiellon, Klara, Livius, Nicolaus, Pegasus, Punkta Terra) of sugar beet was studied. The plots of PD Špačince are located in a beet production area at an altitude of 153–179 meters above sea level. The area belongs to the warm, very dry areas of Slovakia. By evaluating the results of the experiments, we have established a highly significant influence of temperature and humidity conditions of the tested years, as well as of the variety, on the root yield and sugar content. In 2020, a higher average root yield was achieved in the experiments (81.12 t·ha–1), while in 2019 a lower average yield of 74.59 t·ha–1 was recorded. The highest root yields were achieved in both years by the Pegasus variety, 95.75 t·ha–1 in 2020 and 84.88 t·ha–1 in 2019 with declared tolerance to drought. With a higher root yield in 2020, we also observed a higher yield variability of the tested set of varieties in the range of 22.79 t·ha–1 compared to 2019 with a root yield range of 19.47 t·ha–1. The average sugar content of the tested varieties was statistically significantly different between the years, with a higher average sugar content in 2019 (14.45%), while in 2020 the average sugar content was 14.25%. Statistically, the highest average sugar content in the tested years was found in the Nicolaus variety (15.9%). None of the varieties had individually statistically significantly different sugar content when comparing the same variety between the climatically different years 2019 and 2020, which indicates a higher stability of sugar content compared to the sugar beet root yields in the tested location.
