Field experiments were conducted from 1995 to 1997 in order to evaluate seed yield and its structure in four soybean cultivars: Aldana, Polan, Progres, and Nawiko; in 1997, a cultivar Gaj was included. Seed and protein yields were significantly affected by the soybean cultivars. Of the cultivars under study, the highest yields of seeds and protein were obtained from cv. Nawiko and cv. Aldana. High yields of cv. Aldana resulted from its mass of 1,000 seeds, and those od cv. Nawiko from high number of pods per plant. The cultivars compared, had similar protein content (31.8-33.0%). The highest indices of nutritive value of protein showed cv. Nawiko.
