To develop a model of environmental control harmful species of weeds at various systems of the basic soil cultivation and predecessors in short rotations is the purpose of research. Research Methods: Field, statistical. Theoretical and practical results: The analysis of weediness and competitive ability of winter wheat, soybean depending on the methods of basic processing in short-rotation three-field field crop rotation It is found that carrying out plowing at a depth of 20-22 cm in winter wheat helps reduce the total number of weeds in a 1.0-1.3-fold compared with loosening to the depth of 16-18 cm, and with disking of soil to a depth of 10-12 cm . in crops of soybeans reduce the total number of weeds 1.1 times helps hold soil disking to a depth of 10-12 cm compared with plowing to a depth of 25-27 cm. The highest competitive ability of buckwheat noted when placing it in short field rotation after sugar beet, where debris fell to 60.4%, and grain yield - 0.10 t / ha. The broad bean crops after spring barley, respectively, 58.2% and 0.11 t / ha. When carrying out the basic polishing of the soil, the smallest potential ability of germination of weeds in field crops was noted. Novelty: the features of cultivated plants are established in terms of their competitiveness in relation to weeds. The optimal agrotechnical methods of control of weediness in crops of field crops are substantiated, which will allow reducing the chemical load on soil and plants, provide ecological requirements for growing agricultural products and preserving the environment, saving energy costs by 10-15%. The efficiency of application: economic effect of 0.25 thou. UAH / ha The sphere of application is agricultural enterprises of various specialization for the conditions of the western part of the Forest-steppe.
