Productivity of spring spiked crops when using biological products based on Bacillus subtilis in the conditions of the Republic of Tatarstan

Abstract

The effectiveness of the use of an experimental strain of Bacillus subtilis RECB-95B in the treatment of seeds of barley and spring wheat against diseases was studied. The growing season during the years of research was favorable for the growth and development of the tested crops. Barley and spring wheat seeds were treated with various doses of the experimental preparation. The scheme of the experiment included: control without seed fertilizing; the industrial biological product Rhizoplane was used as the standard. The smallest development of striped and brown spots on plants was noted on the variant, the seeds of which were treated with the biological product Rhizoplane. Plant damage by net blotch and root rot was minimal in the variant with Bacillus Subtilis RECB-95B 2.0l/t seed treatment. The highest yield of barley and spring wheat in the experiment was achieved with the treatment of seeds with Bacillus Subtilis RECB-95B 2 l/t (3.23 t/ha and 3.47 t/ha).
