This article presents the results of studying the effect of pre-sowing treatment of lentil seeds with microbiological fertilizers. The issues of the influence of pre-sowing seed treatment with microbiological fertilizers on the growth power, the timing of interphase periods, plant survival and safekeeping, elements of productivity and grain yield are considered. The purpose of the research is to study and substantiate the inoculation of seeds with microbiological fertilizers as an independent technique in the technology of lentil cultivation, which ensures an increase in crop yield. As a result, it was found that inoculation of seeds with Azotovit, Phosphatovit and the mixture of both increases plant safety by 6.0...8.4% and plant survival by 7.0...9.6%. It has been shown that inoculation of seeds with microbiological fertilizers contributes to the formation of higher yields. The greatest increase in yield was obtained in the variant where the seeds were treated with a mixture of Azotovit and Phosphatovit – 0.38 t/ha. The increase in yield after inoculation of seeds with Azotovit and Phosphatovit separately was slightly lower and amounted to 0.31 and 0.34 t/ha. Thus, inoculation of seeds with microbiological fertilizers can be considered as an independent technique in the technology of lentil cultivation, which ensures an increase in crop yield.
Keywords: lentils, variety, microbiological fertilizers, vegetation period, growth power, grain yield.
