Soybean protein and oil content in different growing conditions

Abstract

The objective of the study was to evaluate protein and oil content in grain of soybean cultivars released in Maize Research Institute Zemun Polje. Cultivars ZPS 015, Lidija i Nena have standard grain quality, while cultivars Laura an Lana are without Kunitz trypsin inhibitor in the mature grain. The seed samples are obtained from the network of macro-experiments set up at 6 locations in Serbia during year 2009. The protein content, expressed as % of dry matter ranged from 33.68% in cultivar Lana to 36.60% in cultivars Nena and ZPS 015. The protein content per location varied from 34.11% in location Subotica to 37.32% observed in location Sabac. The highest average oil content (20.33%) was found in the variety Lana and the lowest 18.02% for variety Nena. Location with the highest oil content was Subotica (19.79%) while Sabac was location with lowest oil content 18.27%. The presence of Kunitz trypsin inhibitor did not significantly affect the total content of protein and oil.

Proučavan je sadržaj ulja i proteina u zrnu sorti soje Instituta za kukuruz, ZPS 015, Lidija i Nena standardnog kvaliteta zrna i Lana i Laura bez Kunitz tripsin inhibitora u zrelom zrnu. Seme je uzeto iz mreže makroogleda 2009 godine sa 6 lokacija. Sadržaj proteina, izražen u % od suve materije, se kretao od 33.68% kod sorte Lana do 36.60% kod sorti Nena i ZPS 015. Sadržaj proteina po lokacijama je varirao od 34.11% u Subotici do 37,32 u Šapcu. Najviši prosečan sadržaj ulja od 20.33% utvrđen je kod sorte Lana a najniži 18.02% kod sorte Nena. Subotica je bila lokacija sa najvišim sadržajem ulja od 19.79% a Šabac sa najnižim 18.27%. Prisustvo Kunitz tripsin inhibitora nije značajno uticalo na ukupan sadržaj proteina i ulja.
