Abstract. In conditions of changing climate, it is relevant to increase sown areas under drought-resistant crops such as millet, soybean, chickpea, grass pea, etc., as well as under new varieties able to withstand abiotic stresses. Their yields are strongly determined by weather conditions, so it is necessary to develop agronomic practices that can reduce the negative impact of the environment, increase plant resistance and create favorable conditions for their growth and development. The aim of the research was to study the effectiveness of microbiological preparations on promising varieties of chickpea and grass pea. Experimental work was carried out by field methods in the experimental field of the Laboratory of Genetics and Biotechnology, and by laboratory methods in the Laboratory of Plant Physiology and Biochemistry of FSBSI FSC LGC in 2020-2022. As a result of this research, it was found that the application of microbiological preparations stimulated the growth and development of plants of different varieties of chickpea and grass pea. The maximum positive effect on biomass accumulation was observed in the variant with the application of rhizotorphin (strain 527 for chickpea and strain 2803 for grass pea). Presowing inoculation of seeds with microbiological preparations increased protein content in chickpea grain by 0.6-0.8%, in grass pea grain by 0.4-0.5% compared to the control. The greatest effect was achieved with the application of rhizotorphin and rhizobinagro on chickpea and rhizotorphin, rhizobinagro, and microbiocomagro on grass pea. Microbiological preparations increased chickpea grain yield by 8.0-18.6%, grass pea grain yield by 1.1-5.1% compared to the control. The data obtained can be used to develop technology elements for cultivating chickpea and grass pea crops with high symbiotic responsiveness.
