The aspects of productivity and profitability increasing in spring wheat grain production in Krasnoyarsk region

The aim of the research was to study the effect of different cultivation elements on the grain yield of soft spring wheat. The tasks were set: to determinethe intensification effect of cultivation technology elements on the productivity of spring wheat grain, to study the variation of crop yield depending on applied predecessors, mineral fertilizers and a complete list of modern plant protection products and to establish a background of previous cultures, cultivation that has the highest profitability and the lowest environmental burden on agrophytocenosis. For the identification of the role of predecessors, a complex of modern means of protection and fertilizers on the efficiency of zoned variety of soft spring-sown wheat Novosibirskaya 31 in 2016- 2017 in Krasnoyarsk forest-steppe the field experiment was put. The predecessors were bare fallow and cereals (spring wheat).
