Influence of bacterization upon productivity of soybean

Abstract

Objective. To investigate the effect of pre-sowing bacteria of seeds with diazotrophs Vgasyugiobium iaropysit and AgovirShit Lgavnepve on the effectiveness of the symbiosis of bulb bacteria with plants and soybean productivity. Methods. Field, laboratory, statistical. Results It is shown that complex pre- sowing bacteria of soybean seeds contributes to increasing the number and weight of tubers, increasing the activity of nitrogen fixation in the root zone of plants. With the use of mixed cultures of diazotrophs, the yield of soybeans increases by 0.23 - 0.41 t / ha, or 9 - 16%, compared with inoculation by pure culture of bulbous bacteria. Conclusions The expediency of use of an inoculant on the basis of mixed cultures of microorganisms V. iaropisit and A. bogavieviev in the technology of soybean cultivation has been established.
