Abstract
In studies conducted in the conditions of the Ryazan region on gray forest soil, the effectiveness of the joint use of types of soil treatment and herbicides in winter wheat crops was determined. Phytosanitary, yield and economic indicators in the technology of wheat grain production, depending on factors, are determined. Ac-cording to the results, the species composition of weeds in winter wheat agrocenoses was determined, where 34 species were identified, among which 12 are the most common, from the families of haze, cabbage, cere-als, aster, buckwheat and others. In the experiment, the most effective way of pre-sowing tillage is determined by cultivation. The greatest increase in yield and the maximum economic effect is provided by the herbicide Prishans, SE, at a dose of 0.6 l / ha, used at the beginning of the phase of entering the wheat tube, provided that it is processed in the early phases of weed vegetation development. On average, according to the years of the study, the maximum yield of winter wheat was noted on variants with cultivation during the treatment of crops with herbicides Prishans, SE (43.2 c/ha) and Dianat, BP (42.0 c/ha). The maximum increase relative to the control, on average for two years, was 48.4% (+14.1 c/ha) on the variant Cultivation + herbicide Prishans, SE.
