ield experiment was established in University farming business in Oponice (48° 28´N, 18° 9´E) to evaluate the influence of abiotic and biotic factors on formation of the yield components and the yield of soybean in 2004 – 2006. The number of plants per m 2 , number of pods per plant, number of seeds per pod, thousand of kernels weight and grain yield by variety Korada and OAC Vision were tested. Variants of fertilization: (1) unfertilized treatment, (2) LAV 27% (40 kg ha -1 nitrogen) in the growth stage of first pair of true leaves, (3) Humix komplet (rate 8 l ha -1 ) applied twice in the stage of first pair of true leaves and before flowering. The yield of seeds was statistically significantly influenced with year and fertilization, but yield was not significantly influenced by studied varieties. Higher yield was reached by the variety Korada (4.24 t ha -1 ) than by the variety OAC Vision (3.87 t ha -1 ). The yield was positively influenced by application of Humix komplet fertilizer.
