Abstract
The objective of the study was to investigate the effect of interrow spacing of three soybean cultivars differing with regard to the length of the vegetation period on yield and fertility properties. The highest average seed yield (4943 kg/ha) for the cultivars tested was achieved employing a 20 cm interrow spacing and the lowest (3935 kg/ha) at a 70 cm interrow spacing. On average, the cv. Dragana was registered to achieve by 7.40% higher seed yields compared with the cv. Balkana and by 20.49% compared with the cv. Bosa. Compared with the 70 cm interrow spacing, the 20 cm interrow spacing was noticed to contribute to 9.36% higher stalks, 28.10% greater number of side branches, 5.95% greater number of pods per plant, 4.02% greater number of seeds per plant, 5.13% greater seed weight per plant and 13.17% greater 1000-seed weight.
Ispitivan je uticaj veličine rastojanja između redova (20, 45 i 70cm) na prinos i komponente rodnosti tri sorte soje (Bosa, Balkan i Dragana). U proseku za sorte, najveći prinos semena (4,943 kg/ha) postignut je pri setvi na 20cm rastojanja između redova, a najmanji (3,935 kg/ha) pri setvi na 70cm. U proseku za načine setve, sorta Dragana je imala veći prinos semena za 7,40% od Balkana i za 20,49% od sorte Bosa. U ispitivanjima uticaja oblika vegetacionog prostora i važnijih morfoloških osobina i komponenata rodnosti sorti soje postignuti su sledeći rezultati: U kombinacijama setve na najmanjem međurednom rastojanju (20cm), u proseku za sorte, visina stabala je bila veća za 9,36%, broj bočnih grana za 28,10%, broj mahuna po biljci za 5,95%, broj zrna po biljci za 4,02%, masa 1000 zrna za 5,13% i masa zrna po biljci veća za 13,17% nego pri setvi na najvećem rastojanju (70cm). U proseku i pojedinačno za načine setve, visina stabala i masa 1000 zrna bile su najveće u sorte Balkan, a sva o...stala ispitivana obeležja u sorte Dragana.
