Corn grain productivity and quality at applying of mineral fertilizers in the conditions of the Amur region

The indicators of productivity and quality of grain of corn of the variety Bircy at using mineral fertilizers which efficiency depends on temperature condition and security with moisture during vegetation were presented in the study. In the country the increase in the area of crops and production of grain of corn was noted every year. So, in 2010 under culture there were 1410 thousand hectares, and in 2017 - 3019 thousand hectares. Along with the growth of the area of crops the technology of cultivation of this culture was improved - modern varieties and hybrids which were most adapted for soil climatic conditions of concrete regions were introduced. The purpose of the researches was to study the formation of productivity of grain of corn and its quality depending on the security with the elements of mineral food and conditions of vegetative period. The researches were conducted on experimental field of All-Russia Scientific Research Institute of Soybean, on meadow chernozem soil...
