In the control variant without fertilizer, protein was 9.2%, starch was 50.4%, oil was 4.5%, and ash was 1.27%. 100 kg of Diammofos per hectare, the indicators are 9.5; 56.9; 5.2 and 1.36%, 10.7 in the variant applied Diammofos 120 kg; 60.7; 5.7 and 1.48, %, indicators 10.9 in the variant applied Diammofos 140 kg; 61.7; 6.0 and 1.54%, Diammofos 160 kg, the indicators were 9.8; 58.2 5.4 and 1.40%. In the version where (NH4)2SO4+(NH4)2HPO4 +K2SO4 Ammofoska 100 kg per hectare was applied, the indicated indicators were 9.7; 58.3; 5.6 and 1.39%; Ammofoska -140 kg in the version applied 11.5; 64.7; 6.2 and 1.61 %, (NH4)2SO4+(NH4)2HPO4 +K2SO4 Ammofoska 160 kg per hectare was applied ,the indicated indicators were 10.1; 59.6; 5.8 and 1.48%. In the control option without fertilizer, the grain yield of corn was 57.0 s/ha, and the fodder unit obtained for grain yield was 78.2 s/ha, while in the option given Diammofos -100 kg per hectare, those indicators were 69.8 s\ha and 80.6 s/ha; 74.5 and 84.7 s/ha in the variant applied Diammofos-120 kg; Diammofos -140 kg was 78.7 s/ha and 87.2 s/ha. Diammofos -160 kg was 68.3 s/ha and 81.3 s/ha. In the case of Ammofoska 100 kg per hectare, those indicators are 68.0 s/ha and 82.4 s/ha; - 75.6 s/ha and 86.6 s/ha in the variant applying 120 kg; It was 80.3 s/ha and 88.1 s/ha in the variant applying 140 kg. It was 68.8 s/ha and 83.0 s/ha in the variant applying 160 kg.
