EFFECTIVENESS OF APPLYING MICROORGANISMS ISOLATED FROM EARTHWORM COPROLITES IN INCREASING YIELDING CAPACITY OF GRAIN CROPS
The field experiments for evaluating the effectiveness of pre-sowing treatment of wheat and barley seeds with bacteria Pseudomonas sp. and Bacillus sp. isolated from earthworm coprolites have shown that positive effects of bacterization are most noticeable against a background of unfavorable external factors. Thus, under relatively optimal weather conditions in 2011, bacterization contributed to increasing yields of wheat and barley by 14-35% and 20-22%, respectively, due to producing microbial plant growth promoters and reducing a degree of root rot infestation. Bacterization of grain crops in dry 2012 ensured the increase in yields of wheat and barley by 60-67% and 11-27%, respectively, owing to stimulating root development and increasing resistance of plants to lack of available moisture reserves in soil. Pre-sowing seed treatment with bacterial cultures studied, besides increasing yields, provided a tendency towards improvement of grain quality owing to increasing protein and gluten contents in relation to the control and treatment with a chemical drug.
