aref2 We studied the possibility of cover crops cultivation and their influence on the fields infestation. On the average for 3 years of researches it was established that the winter rye and winter triticale were superior to the yield of green mass of annual grasses at 126 and 88% respectively. The average yield of green weight of cover crops is formed at the level of 8.0-9.0 t/ha. Accounting of contamination was carried out during the growing season of the major and cover crops. The most contamination of the main culture had winter triticale, which is associated with a lower stand density culture. On average, the greatest number of weeds among cover crops shoots was observed on oilseed radish and white mustard, where the infestation was higher by 7-8% in comparison with annual grasses (control). Total number of weeds before the harvest of cover crops was reduced by 2 times compared to the number of weeds in the shoots phase. The total density of the weeds decreased, because annual grasses suppressed weeds, and culture of the cabbage family, due to secretions, acted inhibitory to weeds development. So, this research found that rotation part "the basic culture - cover crops" reduces the contamination of crops considerably by moving crops and tillage and the cover crops inhibitory effect during their growing season.
