Abstract: The purpose of the study is to assess the effect of foliar fertilizing with nitrogen fertilizers on the productivity of emmer wheat. Field experiments were conducted in 2021-2023 on gray forest soils of Agrobiotechnopark LLC at the Kazan State Agrarian University. Agrochemical indicators of the site: humus content of 3.6%, mobile phosphorus according to Kirsanov in the modification of TSINAO 262 mg / kg, exchangeable potassium 125-185 mg/kg, soil acidity – 6.2 pH. The doses of mineral fertilizers were determined by the calculation and balance method to obtain 3 tons / ha of grain, which amounted to N35P23K5. Against the fertilizer background designed to yield 3 t/ha over the years of research, the yield increase according to the k-10456 sample was 0.35 t /ha, according to the Fleece variety 0.1 t /ha. The use of the fertilizer background and one foliar fertilizing N15 in the tube exit phase gave an increase of 0.53 t/ha for the k-10456 sample, and 0.1 t/ha for the Fleece variety. Two foliar fertilizing according to N7,5 in the phase of entering the tube and earing provided an increase of 0.67 t/ha according to the k-10456 sample, and 0.07 t/ha according to the Fleece variety. The background of mineral nutrition and foliar fertilizing contributed to the formation of a larger grain, compared with the control of emmer wheat, and also did not allow a large decrease in the mass fraction of protein in the grain.
