Sažetak
Six field experiments were carried out during three years (1999-2001) at two locations (Osijek and D. Miholjac)to determine the fertilization influence on yield of early Savoy cabbage (Brassica oleracea L. var. sabauda). The experiments were conducted in 1999 and 2001 with five N-fertilization levels (0, 50, 100, 200 and 300 kg/ha N), 100 kg/ha P2O5 and 300 kg/ha K2O. Yields were measured for each of four replicates. Yield of Savoy cabbage heads were 25.4 (without fertilizer) to 66.2 t/ha (highest fertilizationa rate) in D. Miholjac and 24.3-59.2 t/ha in Osijek. The average weights of Savoy cabbage heads were 406-1059 and 389-947 g, respectively. The fertilization increase resulted with yield increasing on both localities, but year did not affect yield. Experiments with five N levels producted yield increasing up to highest N-level (300 kg/ha) but each linear increment of N-fertilization resulted with lower yield increase then the previous one. With the two levels of N, P and K there was also an increase of yield up to the second fertilization level, but the influence of fertilization was significantly lower in Osijek. In conclusion, yield of early Savoy cabbage hybrid increase is higher on the soils with lower available nutrients level.
