Two-year results of corn crop cultivation in tetraculture crop rotations at various soil cultivation (B1, B2, B3) and different fertilisation variants (0, PH, PZ) was gained following: from the point of followed yield components and yield of grain corn the best suited combination was B1 x 0 (conventional soil cultivation on the unfertilised variant) with the highest number of corn cobs per hectare and the highest yield of grain corn. From the point of the number of plants per hectare an optimal combination was B1 x PH (restricted fertilisation) and from the point of the number of corn cobs per plant B2 x 0 (combined tiller). The largest grain corn was obtained by combination B3 x 0 (combined tiller, 2x). Yield elements and grain yield were significantly influenced by year, the number of plants per hectare were significantly influenced by soil cultivation. The influence of fertilisation and soil treatment wasn't significant
