Navodnjavanje je nezamenjiva agrotehnička mera u vreme klimatskih promena koja povećava prinose i kvalitet gajenih biljaka. Soja veoma pozitivno reaguje na navodnjavanje, naročito u godinama sa izraženom sušom u vreme formiranja i nalivanja zrna. Navodnjavanje je u nepovoljnoj 2022. godini povećalo prinos soje od 41 do 94%, a u povoljnoj, 2023. godini od 13,99 do 15,46%. Usled navodnjavanja smanjen je sadržaj proteina, povećan sadržaj ulja i povećan prinos proteina i ulja po jedinici površine., Irrigation is an irreplaceable agrotechnical measure in times of climate change that increases yields and the quality of cultivated plants. Soybeans respond very positively to irrigation, especially in years with pronounced drought at the time of grain formation and pouring. Irrigation increased soybean yield from 41% to 94% in the unfavorable year 2022, and from 13.99% to 15.46% in the favourable year 2023. As a result of irrigation, the protein content decreased, the oil content increased and the yield of protein and oil per unit area increased.

Tokom 2016, 2017. i 2018. godine ispitivana je primena NPK đubriva, efektivnih mikroorganizama i kombinacija NPK đubriva i efektivnih mikroorganizama na prinos, sadržaj proteina i ulja kod šest NS sorti soje. NPK đubrivo i efektivni mikroorganizmi imaju pozitivan uticaj na prinos soje i kvalitativne osobine zrna. Primena efektivnih mikroorganizama i NPK đubriva statistički značajno povećava prinos, sadržaj proteina i sadržaj ulja u zrnu soje., During 2016, 2017 and 2018, the application of NPK fertilizers, effective microorganisms and combinations of NPK fertilizers and effective microorganisms on yield, protein and oil content in six NS soybean cultivars was examined. NPK fertilizer and effective microorganisms have a positive effect on soybean yield and grain quality. The application of effective microorganisms and NPK fertilizers statistically significantly increases the yield, protein content and oil content in soybean grain.

Cilj ovoga rada je sagledavanje prinosa, sadržaja proteina i ulja, kao i prinosa proteina i ulja po jedinici površine, najnovijih NS sorti soje priznatih u 2019. godini. U dvogodišnjim ogledima Ministarstva poljoprivrede, šumarstva i vodoprivrede, na pet lokaliteta, najviši prinos imala je kasna sorta soje NS Vaso (4241 kg ha-1). Najviši sadržaj proteina imala je rana sorta NS Olympus (41,40%), dok je najviši sadržaj ulja zabeležen kod srednjestasne sorte soje Sava (21,89%), The Department of soybean, Institute of Field and Vegetable Crops in Novi Sad has so far registered 148 NS soybean varieties of different maturity groups. The aim of this study is to assess the yield, protein and oil content, as well as protein and oil yield per unit area, the latest NS varieties registered in 2019. In the two-year trials of the Ministry of Agriculture, Forestry and Waters, at five locations, the highest yield had late soybean NS Vaso (4241 kg ha-1). The highest protein content was early variety NS Olympus (41.40%), while the highest oil content was recorded in medium maturity varieties Sava (21.89%).

U dvogodišnjim ogledima Ministarstva poljoprivrede, šumarstva i vodoprivrede, na pet lokaliteta, najviši prinos imala je kasna sorta soje NS Vaso (4581 kg ha-1). Najviši sadržaj proteina imala je rana sorta NS Olympus (41,58%), dok je najviši sadržaj ulja zabeležen kod srednjestasne sorte soje Sava (21,80%)., The Department of soybean, Institute of Field and Vegetable Crops in Novi Sad has so far registered 148 NS soybean cultivars of different maturity groups.

Nove sorte soje testiraju se u mreži makroogleda, a ovi rezultati, uz rezultate demonstracionih i proizvodnih ogleda doprinose odabiru najprinosnijih sorti soje za određene lokalitete gajenja. Cilj ovoga rada je sagledavanje prinosa, sadržaja proteina i ulja, kao i prinosa proteina i ulja po jedinici površine NS sorti soje u 2018. godini. Sorta soje NS Kraljica ostvarila je najviši prinos zrna (4369 kg ha-1), sorta NS Kolos imala je najviši sadržaj proteina (41,4%), sorta NS Atlas najviši sadržaj ulja (21,7%), dok je najviši prinos proteina (1745 kg ha-1) i ulja (915 kg ha-1) po jedinici površine ostvaren sa sortom soje NS Kraljica., New soybean varieties are tested in the macro trials and these results, together with the results of demonstration and production experiments contribute to the selection of the most yield producing of soybean for certain cultivation sites. The aim of this research is to examine the yield, the content of proteins and oils, and the yield of proteins and oils per unit of NS surface of soybean varieties in 2018.The NS Kraljica variety had the highest grain yield (4369 kg ha-1), the NS Kolos variety had the highest protein content (41.4%), the NS Atlas variety was the highest oil content (21.7%), while the highest protein yield (1745 kg ha-1) and oil (915 kg ha-1) per unit area realized with the variety NS Kraljica soybean.

Folijarni tretmani dva puta u vegetaciji sa efektivnim mikroorganizmima značajno su uticali na povećanje prinosa ispitivanih parametara. U godini sa nepovoljnim agrometeorološkim uslovima zabeleženo je povećanje prinosa zrna u zavisnosti od količine osnovnog đubrenja od 9,59-3,94%, dok je u godini sa povoljnim uslovima to povećanje iznosilo od 4,81-1,83%. Takođe, je utvrđen i povećan sadrćaj ulja u zrnu i prinos ulja po jedinici površine. Uvođenjem efektivnih mikroorganizama kao obaveznu meru uticalo bi se na smanjenje efekta suše, sigurniju proizvodnju i dobar kvalitet zrna., Foliar treatments twice in vegetation with effective microorganisms significantly influenced the increase in the yield of the tested parameters. In the year with unfavorable agro-meteorological conditions, the increase in grain yield was observed, depending on the amount of basic fertilizer from 9.59-3.94%, while in the year with favorable conditions the increase was 4.81-1.83%. It is established and increased oil content in grain and oil yield per unit area. By introducing effective micro-organisms as a compulsory measure, it would have an effect on reducing the effects of drought, more secure production and good grain quality.

The effect of genotype, seed category and year on yield components (number of spikelets per spike, grain number per spike, grain weight per spike and thousand grain weight) for three wheat genotypes were studied during a two-year research. Genotype PKB Lepoklasa and seed category pre-basic seed had the highest values for the largest number of the studied traits, while the genotype BG Merkur and the certified seed of the first generation had the lowest values. Higher values for the studied traits were found in 2010, compared to 2009. AMMI analysis established a significant effect of the interaction of factors and main components (PCA 1 and PCA 2) for all investigated traits except thousand grain weight. The genotype PKB Talas was the most stable, while the genotype PKB Lepoklasa was the least stable. Seed categories certified seed of the first generation and basic seed had similar reactions to the interaction between factors.
