This article points out the ways of efficient plant nutrition with microbiological fertilizers on various mineral nutrition backgrounds. Current research is aimed at managing high lentil yields with substantiate application of microbiological fertilizers on mineral nutrition background. The article describes the elements of yield structure and grain productivity of lentil: the number of beans and seeds per plant, the weight of seeds per plant, and the weight of 1000 seeds, which is important for predicting the efficiency of a particular cultivation technique. The effect of microbiological fertilizers on the height of the lower bean attachment is assessed. It was observed that a mixture of Azotovit + Phosphatvit exerted a positive impact on this morphological trait. The obtained results allowed us to conclude that seed treatment with a mixture of Organit N + Organit P at a rate of 0.5 l/ha contributes to high lentil yields, regardless of the mineral nutrition backgrounds. Fertilizer application on the N32P32K32 background ensured a higher yield increase. The highest yield was noted with N32P32K32 when sowing lentil seeds with a mixture of Organit N + Organit P treatment at a rate of 0.5 l/ha.
Keywords: lentil, microbiological fertilizers, mineral nutrition background, productivity, yield.
