The effect of different organic materials, microbial and mineral fertilizers were investigated in Mitscherlich pots, on two soils with different fertility level (unfertilized/fertilized two-crop rotation) on the yield, and quality parameters of yellow pepper (Capsicum annuum L). Following treatments were applied: control without fertilization (0); mineral N-fertilizers (ammonium nitrate) (AN); concentrated poultry manure (KZS); green mass of alfalfa (L) and also of cabbage (K); microbial fertilizer (MDJ) without and with wheat straw (S+MDJ). Concerning the yield and number of fruits per plant, the significantly better results were found on high fertile soil. However, on less fertile soil, the highest yield was obtained with KZS (156.38), L (141.22) and AN (120.09 g/plant). Microbial fertilizer (84.06) and K (80.11) did not have positive effect on yield compared to control (85.57), while treatment S+MDJ (53.16 g/plant) caused the lowest yield. The effect of fertilizers applied was significantly lower on high fertile soil. Higher yield was obtained with KZS, L and also K (170.07; 166.75; 159.17; 151.74 g/plant, respectively), although it was not significantly different compared to control (127.28) and MDJ (124.54 g/plant). The lowest yield was measured with S+MDJ (80.79 g/plant).
