EFFICIENCY OF FERTILIZATION AND SOIL CULTIVATION IN CROP ROTATION
2008, 9 (3) p. 519-525
The experiment with the crop rotation: winter wheat, pea, corn, spring barley and cow-grass were founded in 2001- 2004. We examined the effect of the preceding crop, the soil cultivation and fertilization on yield of grain of the main product. The methods of soil cultivation: tillage to the depth of 0.25 m, to the depth of 0.15 m and cultivation where we used disk tools to the depth of 0.10 m. In the variants of fertilization had been used fertilization of the artificial fertilizer with the balance method and fertilization with the artificial fertilizer with the placement of the remains of the preceding crop. By grain corn were statistically significant yield achieved after the tillage to the depth of 0.25 m and 0.15 m. Spring barley reacted positive on the soil cultivation with disk tools. Yield of the winter wheat and the pea were not statistically significant. Fertilization affected statistically significant on yield of winter wheat. The effect of the artificial fertilizers and the residues of the preceding crop on yield of corn, spring barley and pea did not show statistically significant.
