Influence of biopreparations on the yield of chickpea

The influence of pre-sowing inoculation of chickpea seeds by microbial strains on the change in the effective fertility of chernozems was evaluated. The content of nitrate nitrogen at the beginning of the growing season increased by 0.7-1.7 mg/kg. The positive effect of symbionts on the amount of chlorophyll accumulation in chickpea plants was established. A significant increase in plant productivity was shown when inoculants were used. Rhizotorphin strains increased grain harvest to 1.85 t/ha with a control yield of 1.51 t/ha.
