Abstract
The article considers the reaction of the variety «Novosibirskaya 15» to the use of insecticides, fungicides, herbicides, as well as nitrogen fertilizers. Maximum yield of modern spring wheat varieties can be expected only when they are cultivated with elements of intensive technology in crop production. These are the improvement of soil fertility, the system of fertilizers and crop rotations, the use of zoned varieties, the integrated system of plant protection, the improvement of the tillage system, complex mechanization, etc. The fulfillment of these conditions makes a huge contribution to obtaining a high grain yield of excellent quality. In this regard we have studied individual elements of intensive technology and their contribution to the yield of one of the most popular varieties in the Krasnoyarsk Territory. The influence degree of pesticides and fertilizers usage on the elements of the crop structure and its quantity in the spring soft wheat variety «Novosibirskaya 15» was determined by the methods of mathematical statistics. It was established that in order to obtain the maximum productivity of this variety in the Krasnoyarsk Territory it is recommended to use both previous fallow and grain with maximum intensification and fertilization.
