Both yield and quality of soybean grains of various cultivars under different agroecological conditions were studied for a couple of years. The soybean cultivars of the Belgrade Company Selsem (Serbia): Dukat (maturity group O), Galeb (maturity group 1st), and Gorštak (maturity group 2nd) having different vegetation period lengths were used in the trial. Field trials were conducted on different soil types and at various sites. Depending on the vegetation year and site, grain yield of the early maturing cultivar (maturity group O) ranged from 1.39 to 5.47 t/ha; grain yield of the maturity group 1st cultivars was 1.38 to 5.48 t/ha and that of the late maturing cultivars (maturity group 2nd) 1.38 to 5.55 t/ha. On average, the highest soybean grain yield (3.86 t/ha) was obtained with the cv. Gorštak followed by cv. Galeb (3.72 t/ha). The cv. Dukat was the least yielding (3.53 t/ha). The share of raw proteins in the predominantly dry soybean grain varied from 42.16% in the cv. Gorštak to 44.03% in the cv. Dukat. Oil content ranged from 20.35% in the cv. Galeb to 20.53% in the cv. Gorštak. Based on the results obtained it can be concluded that, in contrast to oil content, there was negative correlation between protein content and yield of the cultivars studied.
