The aim of the article is to study the effect of various biological agents of biofungicides on plant resistance to drought and formation of spring barley crops. Endophytic bacteria (Bacillus subtilis), rhizospheric bacteria (Pseudomonas fluorescens), actinomycetes (Streptomyces sp.), and micromycetes (Trichoderma viride) were used as bioagents of biofungicides. Preparations based on biological agents were used to treat spring barley seeds. The studies were carried out in laboratory and field conditions. In the conditions of the model artificial acute drought, it was found that seed treatment with Streptomyces sp. Stimulates the leaf and root growth, as well as increases peroxidase activity in the leaves. The maximum content of proline was during seed treatment with Pseudomonas fluorescens. An increase in the content of chlorophyll was observed when treating with Trichoderma viride seeds. In the field conditions, Pseudomonas putida and Streptomyces were more efficient by the content of proline in seedlings. In terms of the spring barley yield, seed treatment with Streptomyces sp., Pseudomonas putida and Bacillus subtilis was more efficient. Streptomyces sp., Pseudomonas putida and Bacillus subtilis are promising for increasing barley resistance to drought.
