THE INFLUENCE OF MINERAL FERTILIZERS, SEED AND CROPS TREATMENT ON SPRING WHEAT PRODUCTIVITY IN THE CONDITIONS OF KAMA REGION OF THE REPUBLIC OF TATARSTAN

Improving the efficiency of fertilizers used, growth stimulants, taking into account active phases culture development remains relevant. The purpose our study is to identify impact calculated doses nutrients, pre-sowing seed treatment and vegetative plants with a stimulant on productivity spring soft wheat. Field experiments laboratory studies were conducted in 2019-2021 gray forest soils Agrobiotechnopark LLC Kazan State Agrarian University. scheme field experiment involved following options: mineral (factor A) - without (0); dose for grain yield 3.5 t/ha (N36P23K35); 4.5 (N94P83K77); stimulants B) Vial Trust 0.5 l/t; l/t + spraying tillering phase Stimax Growth 1 l/ha; Stimaks l/ha booting Nutrivant Plus 2 kg/ha. survival an unfertilized background was 57.7...62.0%, N36P23K35 62.5...67.2%, N94P83K77 71.8...79.8%. complex effect disinfectant seeds ensured increase by 4.3%, against 4.7%, 8.0% . average wheat Ulyanovska 105 variety 3.21 t/ha, 3.69 4.28 t/ha. combined use accompanied 4.7, 5.1 7.0%, respectively.
