The aim of the study was to analyze the influence of interrow spacing (25, 50, and 70 cm) on seed yield and quality of three soybean varieties of different vegetation length (Dukat- 0 group, Balkan - 1st group, Vojvodjanka - 2nd group of maturation). Different interrow spacings contributing to various shapes of the vegetation area using the same plant population density. During the two-year trial, on average with regard to the cultivars tested the highest seed yield (5.312 kg/ha) was obtained sowing at a 25 cm interrow spacing. This was by approx. 40% greater in comparison with the 50 and 70 cm interrow spacing sowing variants (3.798 and 3.807 kg/ha). Considering interrow spacing, on average, the highest seed yield was obtained by cv. Dukat (4.450 kg/ha). Cvs. Vojvodjanka and Balkan yields were by 1.8 and 8.0% lower. Protein content was not substantially effected by the shape of the vegetation area averaging 31%. This was also the case with oil content in the seed (on average 20.8%).
