Abstract
Nowadays, corn is an important source of nutrients in the human diet, as well as a valuable energy feed with the highest digestibility among cereals, a valuable raw material for the food, medical, microbiological, chemical industry and other sectors of the national economy. Increasing of corn grain production is one of the most important conditions for stabilizing the Russian food base. Being one of the technological crops that is demanding to growing conditions, corn is the most productive forage crop. It is important to note that the yield of corn depends not only on the fertility of the soil, but also on the methods of its processing and cultivation. One of the reasons holding back the growth of corn grain production is the high contamination of crops. In this paper, the influence of various cultivation technologies and methods of caring for maize crops on productivity is studied. It is shown that the highest yield and effective protection from weeds is obtained with an optimal combination of chemical and mechanical methods of crop care.
