Abstract

The agronomically valuable bacteria application for increasing of soil fertility and spring barley (Hordeum
vulgare L.) productivity. A.N. BYKOVSKAYA¹, M.L. SIDORENKO¹, N.A. SLEPTSOVA¹, A.G. KLYKOV²,

Timiryazevsky village, Primorsky Krai).

The goal is studying the effect of nitrogen-fixing, phosphate-solubilizing and potassium-solubilizing bacteria on the
spring barley productivity. A positive effect on the available forms of nitrogen, phosphorus, and potassium content in
the soil has been established. In the experimental soils, an increase in the studying bacteria abundance was recorded.
Spring barley yield increasing up to10.8 % was obtained. It has been established that the application of the consortium
including all three bacterial physiological and biochemical groups is the most promising for improving soil environment
properties and spring barley productivity.
