Subject of inquiry - the process of winter wheat productivity formation when growing after winter rape, competitive crop plant-weed interrelations; The purpose - to reveal the details of winter wheat kernel yield and quality formation depending on the fertilizer sistem, agrotechnical and chemical, measures, crop tending; The methods are calculated and weight, chemical, phisical, mathematical and statistical, calculated-comparative; The novelty - for the conditions of the western Forest-Steppe the regularities of wheat field agrophytocenosis formation are established, the details of competitive crop plant - weed interrelation depending on soil tillage method and winter wheat fertilization are determined; The research resalt - the tillage sistem is improved. It is directed to the increase of weed cenosis control in crops of winter wheat as well as the optimal doses and effective methods of fertilizer application are determined; The introduction - the improved growing technology after winter rape was applied to production over an area 370 ha; The branch - agriculture
