THE PROSPECTS OF USING PSEUDOMONAS PROTEGENS DA1.2 BACTERIA TO INCREASE THE YIELD OF SPRING WHEAT IN THE CONDITIONS OF THE BASHKIR URALS

Abstract

The data of 3-year field experience with soft spring wheat in the conditions of the Northern forest-steppe zone of the Republic of Bashkortostan are presented. Treatment with nanomet and chistalan herbicides led to a significant reduction in the number of weeds and a decrease in the threshold of their harmfulness, while herbicides had a pronounced negative effect on the physiological and biochemical processes of wheat plants. The positive effect of the introduction of Pseudomonas protegens DA1.2 bacteria together with herbicides was revealed due to a decrease in the content of MDA, an increase in the content of chlorophylls and nitrogen index, all this led to an increase in yield. According to field experiments, the yield for an average of 3 years was 37.9 c/ha, an increase in wheat productivity of 24.5% or more of the control was observed in variants of joint treatment with bacteria with the herbicides. The studied strain can be recommended for increasing yields and more effective use of herbicides in the conditions of the Urals of the north-western part of the Republic of Bashkortostan.
