This article presents the results of the study on the formation of pea seed yields under the influence of foliar fertilization at different backgrounds of mineral nutrition. The purpose of the study is to substantiate the methods of improving the cultivation technique of pea seeds based on the optimal combination of mineral nutrition backgrounds with the use of foliar fertilizers, the interaction of which ensures high yields. The following objectives were solved: 1. determination of the effect of different mineral nutrition backgrounds in combination with foliar fertilization on the formation of yield structure; 2. determination of the effect of different mineral nutrition backgrounds in combination with foliar fertilization on pea yield. The article deals with the influence of the studied methods on the main elements of productivity: number of beans on a plant, number of seeds in a bean, mass of seeds in a plant, 1000-seed mass. The pea yield as a function of foliar fertilization at different nutrition backgrounds is shown. In the conclusion, it is noted that foliar fertilization with Biostim Universal at a rate of 2.0 l/ha in the stemming + budding phase contributes to a higher grain yield in peas, regardless of the mineral nutrition backgrounds. Fertilization with N16P16K16 leads to higher yield growth. An increase in the fertilizer application rate – N32P32K32 – did not contribute to a further increase in yield. The highest yield is achieved when N16P16K16 is applied with subsequent foliar fertilization with Biostim Universal at a rate of 2.0 l/ha in the stemming + budding phases.
Keywords: peas, yield, productivity elements, mineral nutrition level, foliar dressing.
