EFFECT OF SOIL CULTIVATION TECHNOLOGY AND FERTILIZATION ON SPRING BARLEY ( HORDEUM VULGARE L.) PRODUCTION PROCESS

The influence of conventional and minimal soil cultivation in interaction with mineral fertilization and utilization of the by -product on the spring barley yield, uptake of nutrients by yi eld and energetic effectiveness in experimental years 2004-2006 was investigatedin the experiment. Within each cultivation method, three treatments of fertilization were applied: 0 - control without fertilizing, PH - rational fertilization with mineral fertilizers, PZ - rational fertilization with mineral fertilizers and incorporation of post harvest residues into soil. Different soil cultivation did not influence grain yield of spring barley statistically significantly. It was confirmed that barley does not react substantially onto the depth of soil cultivation. The highest average yield of grain (average of years and soil cultivation methods) was found in treatment with incorporated (ploughed - down) post-harvest residues (PZ). Higher grain yield was achie ved under their shallow incorporation into soil (B
