Responsiveness of spring wheat to the use of chemicals

Abstract

Abstract Increase in grain production in the Krasnoyarsk Territory is possible with the use of three intensification factors in wheat cultivation technology – intensive varieties, increased doses of fertilizers and intensive protection. The fulfillment of these conditions makes a huge contribution to obtaining a high grain yield of excellent quality. In the conditions of agricultural intensification, with the increase in the chemical’s usage prospects for more complete potential realization of spring wheat for the formation of high yields and improving the quality of grain are opening up. The article considers the reaction of the varieties «Novosibirskaya 15», «Novosibirskaya 29», «Novosibirskaya 41» and «Altayskaya 75» to the intensification of cultivation technology. The response of the most popular spring wheat varieties to the use of nitrogen fertilizer, as well as to the introduction of herbicide, fungicide and insecticide in its crops was studied. Methods of mathematical statistics determine the degree of variation in the crop structure, as well as its amount in the above varieties of spring soft wheat after the use of pesticides and fertilizers. It is established that with financial tension in the farms of this zone, it is possible to make a choice in favor of the use of pesticides to control the number of pathogens and weeds in the phytocenosis.
