Influence of the nutritional level and pre-sowing seed treatment on the yield of spring wheat

It remains relevant to meet the needs of plants in nutrients, methods using growth stimulants, considering active phases culture development. The purpose our research is study complex effect level mineral nutrition, pre-sowing treatment seeds, and spraying growing with a regulator on productivity spring wheat. Laboratory field experiments were carried out 2019–2020 based Federal State Budgetary Educational Institution Higher Education "Kazan Agrarian University" gray forest soil. average yield wheat over years against background without fertilizers was 3.94 t/ha, NPK obtain 3.5 t/ha grain – 4.53 4.5 5.24 t/ha. use stimulants during seed double tillering phase into tube contributed an increase all nutritional backgrounds by another 4.9–6.3 %.
