Ivanyuk V. The Сrop Productivity of a Link of Grain Row-crop Rotation Depending on the Basic Soil Tillage Methods and the Levels of Fertilization

Subject of research - the formation process of a crop productivity of and water, physical and nutritive crop rotation link regimes of soil. The purpose of investigations consists in the esteblishmentof the effective influence of the basic tillage methods and a level of fertilization of the grey forest soil on their fertility, weediness, productivity and yeid quality. The research methods are field, visual, measuring and weight, analytic, mathematical and statistical, computational and comparative. The value and novelty of investigations consist in the determination of the effect of soil tillage methods and fertilizers with using of intermediate plantings and after-products for fertilizing on the details of the formation of produce yield, and qualiti as weed infestation of crop of a grain row-crop link. The optimal parameters of the ploughing horizon fertility of the soil are established. The developed recommendations are introduced at the Experimental Farm "Obroshyno" of the Lviv region. The field of application - the agricultural production.
