Sažetak
During 1995 in Osijek area (Croatia), some field trials were done to determine an influence of soybean seed size (seed fractions 7,5 mm; 6,5 mm and 5,5 mm of diameter) on grain yield components (pod numbers per plant, grain numbers in the pod and 1000-kernels weight). According results, soybean seed fractions have had statistically not significant influences on stem length, by all investigated seed fractions. Also, soybean seed fractions have had statistically very significant influences (P<0,01) on pod numbers per plant. The large seeds achieved, on an average, 25 pods and small seeds only 18 pods per plant. Statistically very significant correlation (r=0,948**) was founded between pod numbers per plant and grain yield. The investigations were shown that seed size has had not the influence on grain numbers in the pod and on 1000-kernels weight. Therefore, grain yield increases per plant, by large seeds, are results of increases of pod numbers per plant. Also, the plants grown from large seeds have achieved the greatest grain yields (12,70 g per plant), and the plants grown from small seeds have achieved the lowest one (8,09 g per plant). The differences in grain yields, found between soybean seed fractions, were statistically very significant (P<0,01). The existing of Heteroptera insects in soybean grain yields was founded by analysis after harvest.
