Abstract

The purpose. To give economic and power assessment of joint application of microbial specimens Khetomic and Diazobacterin in technique of growing of buckwheat of sowing campaign. Methods. Field experiments were spent according to the conventional methodical recommendations. Economic and power efficiency of presowing treatment of seeds of buckwheat microbial specimens Khetomic (bioagent — Chaetomium cochliodes 3250) and Diazobacterin (bioagent — Azospirillum brasilense 18-2) was determined according to basic methodical approaches based on comparison of result got from certain agricultural method with expenditures for its holding. The prices for resources and agricultural products are taken at average actual level on 2017 according to available statistical data. For assessment of reliability of differences between alternatives of experiments they evaluated the least essential variance. Results. By three-year field experiments it is determined that increase of yield in case of preseeding inoculation with Diazobacterin makes 20,6%, presowing treatment with Khetomic — 22 %. The highest result of complex application of microbial specimens — 34,9%. Presowing treatment of seeds of buckwheat with Khetomic and Diazobacterin decreased cost price of a unit of production on 1026 hrn/t, increased conditional profit on 7463 hrn counting upon 1 hectare of the area of sowing, and also raised rated level of profitableness of production of grain of buckwheat on 79,0% that ensured pay-back of additional expenditures with profit at the level of 36,95 hrn/hrn. The quotient of power efficiency at complex use of microbial specimens made 3,64. Thus energy content of yield of buckwheat increased on 12167 MJ/hectare due to heightening exit of produce. Conclusions. On the basis of results of long-term field and farm experiments it is offered to farm-producers to use complex presowing treatment of seeds of buckwheat with microbial specimens Khetomic and Diazobacterin. That is economically and energetically expedient in technique of cultivation of crop.
