INFLUENCE OF BIOLOGIC DRUGS ON PRODUCTIVITY OF WINTER WHEAT UNDER THE CONDITIONS OF THE STEPPE CRIMEA
Abstract
One of the elements of environmental friendly technology of winter wheat growing in the Crimea is an inoculation of seeds with microbial agents based on the effective microbial strains, which allow preserving soil fertility and reducing of the cost of production while increasing productivity. The purpose of the research is to study the effect of pre-sowing treatment of winter wheat seeds with bio drugs ‘Rizoargin’ (on the basis of Rhizobium radiobacter), ‘Fosfoenterin’ (on the basis of bacteria Enterobacter nimipressuralis) and their mixture on the structure of the yield and grain quality. Another aim is to determine economic efficiency of their use in comparison with a technology of wheat growing with spring fertilizing. The conducted in 2011-2012 research showed that a combined use of bio drugs was the most efficient for main traits of grain quality (vitreousness, nature and protein content) compared with standard nitrogen and phosphorus fertilizing. According to the two-year data the use of mineral fertilizers (0,33 - 0,53 t/ha) gave the most increase of productivity, and the use of bio drugs excessed the standard variant on 4,07 - 9,05% (0,10 - 0,19 t/ha). Though the use of microbiologic drugs was more economically efficient (economic return of 2,81-3,1 rub) than the use of mineral fertilizing efficient (economic return of 0-1,1 rub).
