Sažetak
In 2005 and 2006, the influence of fertilization was investigated on forming of yield components and yield of three soybean varieties in sugar beet growing area. Varieties Korada, Supra and OAC Vision were grown. Number of plants per m2, number of pods per plant, number of seeds in pod, thousand seeds weight, yield of seeds, yield of stems and harvest index were examined. Variants of fertilization: I. non-fertilized control, II. LAV 27 % (40 kg ha-1 net nutrient
of N) in growing stage of first pair of true leaves unfolded, III. Humix komplet (rate 8 l.ha-1) applied in growing stage of first pair of true leaves unfolded (4 l.ha-1) and in growing stage of first flower buds visible (4 l.ha-1), IV. Humix komplet in rate 8 l.ha-1 applied in growing stage of first pair of true leaves unfolded. The yields of seeds and stems were high significantly influenced by variety, fertilization and year. The significantly highest yield of seeds was achieved by Korada variety (4,04 t.ha-1). Varieties OAC Vision and Supra reached yields in interval 3,74-3,84 t.ha-1. Split rate of
Humix komplet (III var) significantly influenced yield of seeds and stems. The fertilization have increased weight of seeds in proportion to aboveground phyto-mass weight, what was expressed by harvest index.
