ВЛИЯНИЕ ФАКТОРОВ БИОЛОГИЗАЦИИ НА УРОЖАЙНОСТЬ ОЗИМОЙ РЖИ В УСЛОВИЯХ ПРЕДКАМЬЯ РЕСПУБЛИКИ ТАТАРСТАН

Abstract

The research was carried out on the experimental field of the General Agriculture, Plant protection and Selection Department of Kazan State Agrarian University by bookmarking a long-term in-patient experience. Research was conducted on two bookmarks of the stationary experience of General Agriculture Department in the links of the crop rotation of fallows - winter rye. The following issues were laid and studied at the station: crop rotations, nutrition backgrounds, soil cultivation. One of the tasks, set before the research, was to determine the effect of embedding biological agents into the soil on the indices of soil fertility and on crop yields in crop rotations. Nutrients contributed to the formation of a higher crop, even in the absence of fertilizers, for example, the straw yield was generated 22.5 centner per hectare, and with the use of intermediate syderat - 23.6, while without biogenes - 20.08 centner per hectare. A comparatively high yield was obtained with the use of siderate for a combined treatment system - 26.7 centner per hectare. When the estimated doses of mineral fertilizers were applied into the soil in terms of biologic background, the winter rye productivity increased even further, the increase to the background without fertilizers was 9.6-14.0 centner per hectare.
