THE EFFECT OF CROP ROTATION, TILLAGE TECHNIQUE AND FERTILIZERS ON BARLEY PRODUCTIVITY

According to the trial, started in 1987, the article presents research works made in 1994–2013 dealing with the study of barley productivity during second-fifth rotations of grain-grass row crop rotation and grain row crop rotation grown in blackearth (chernozem) with various tillage technologies and fertilizing. During four rotations on average barley productivity was nearly similar in both crop rotations. According to the trial results, the productive process depends on 0.16% from the types of crop rotations, on 0.12% from tillage technologies, on 25.6% on organic fertilizers and 71.0% from mineral fertilizers. The introduction of mineral fertilizers increases grain yield on 1.04–1.22 t/ha, the introduction of organic fertilizers increases it on 0.73–0.82 t/ha and they are obligatory for grain productivity increase. It has been established that depending on the crop rotations, tillage technologies and fertilizers barley productivity ranged from 2.38 t/ha in the variants without fertilizing to 4.24 t/ha with introduction of NPK100/ha with 16 t/ha of cattle manure.
