The influence of mineral fertilizers and plant protection means on the structure elements and spring rapeseed productivity

The aim of the research was to study the effect of mineral fertilizers and plant protection products on the elements of the crop structure and yield of spring rapeseed in the conditions of the Krasnoyarsk forest-steppe. The research problems: 1) to estimate the schemes of protection of spring rapeseed "Agrochemical of DF" and "Singenta" on the following backgrounds: without using fertilizers; N80 ammonium nitrate; ammonium nitrate + N80P80 ammophos; azofoska of N80P80K80; 2) to estimate the influence of mineral fertilizers on the systems of protection of plants," Agrochemical of DF" and "Singenta". The researches were conducted on the variety of spring rapeseed Nadyozhny 92 in 2017-2019 in the Krasnoyarsk forest-steppe of Krasnoyarsk Region. On four backgrounds two schemes of protection were studied: 1. Protection scheme Agrochemical DF: pre-sowing treatment monsoon, VRK-0.2 l / t, herbicides: Huron, CE-0.5 l / hectare, Elf, CE-0.3 l / hectare, insecticide: Tsunamy - 0...
