Summary:

During the growth season of 1992-1993 both grain yield and quality of 29 soybean cultivars were investigated by means of macrotrials in the area of eastern Slavonia (Osijek and Donji Miholjac). The results of the research showed high variations both in grain yield and grain quality among tested cultivars with variations per growth season and locations. The grain yield ranged from 1.68 to 3.78 t/ha (mean: 2.58 t/ha). In the both years of testing, the average grain yields were higher for all the cultivars tested on the location D. Miholjac in comparison with Osijek. Grain quality depended on cultivars, growth season and locations. The protein content of the analysed grain ranged from 32.48 % to 47.92 % (mean 40.71 %). The oil content of grain ranged from 15.67 to 25.27 % (mean: 20.75 %). These values were calculated on the dry matter basis. The study showed significant differences among cultivars in the grain yield and its quality as well as great impact of the agroecological factors.
