The aim of undertaken investigation was comparison of yielding of three soyabeans, cultivars, a small seed cv. Nawiko and two large seed cv. Aldana and Gaj, as well as influence of sowing date on seed yield and total protein content. The studied cultivars were sown on two dates. The first sowing took place in the middle of April and the second at the end of April or beginning of May. Before sowing the seeds received antifungal treatment and were inoculated with Bradyrhizobium japonicum bacteria. The climatic conditions had significant effect on soyabeans seed yield. A small-seed cv. Nawiko had higher seed yields (1.97 t/ha than the large-seed cv. Gaj (1.94 t/ha and cv. Aldana (0.43 t/ha). The second sowing date increased seed yield
