Abstract. This article presents the results of the investigation of the effects of foliar fertilization with different mineral nutrients on the protein content of pea grains. The effect of weather conditions on protein formation in pea grains has been investigated. The peculiarities of expression of the relative and absolute values of the protein content depending on the level of mineral supply and foliar fertilization are shown. Indicators to characterize the protein yield per unit area are given. The purpose of the study is to determine the optimal combination of technological methods of root and foliar nutrition that contributes to the formation of grains with high protein content at a yield that provides maximum protein yield per unit area. As a result, it was found that the optimal combination of root and foliar nutrition factors is formed when applying mineral fertilizers in the amount of N16P16K16 with subsequent treatment of the crops with the preparation Biostim Universal in the amount of 2.0 l/ha in the phases of stem formation and budding. This variant had the highest grain yield (3.4 t/ha) with a relative protein content in the grain of 29.5 %, which resulted in the highest protein yield per unit area – 1.0 t/ha.
Keywords: peas, foliar feeding, mineral nutrition, protein yield, development phases, yield.
