Results of soybean yield and crude protein content testing of several soybean varieties conducted during 2005, on 12 locations in Backa, Srema and Banat (Serbia) are layed out this project. Also seeding period influence on soybean yield of several agricultural organizations in perennial period was analyzed. Seed yield of early varieties (0 maturity group) varied form 2393 - 4352 kg/ha; 1st group of varieties varied from 2957 - 5475 kg/ha and late varieties (2nd maturity group) varied from 2615 - 5351 kg/ha. Considering the location the highest average yield (4309 kg/ha) was obtained with BG-L-3 genotype and the lowest (3538 kg/ha) with the Afrodita variety. Considering the results of these testing as well as many other testing, crude protein content is in negative correlation with soybean yield. Protein content, expressed in absolute mass of dry soybean, varied from 42.05% (variety Vojvodjanka - location Becej) to 49,49% (variety Dukat - location Vajska) Agricultural organizations which practice very early sowing obtains significantly higher seed yield then the organizations which practice late sowing.
