Productivity And Quality Of Spring Soft Wheat Grain Depending On Root Feeding With Liquid Nitrogen Fertilizers On Black Soils Of South Orenburg Region

Abstract

The relevance of the topic of scientific research is associated with the use of new liquid fertilizers and a growth regulator in spring wheat crops to increase the yield and quality of grain in the central zone of the Orenburg region. Ensuring food security today is becoming one of the most urgent tasks set by the government of the Russian Federation for domestic agriculture. To solve this problem, it is necessary, first of all, to increase the yield of agricultural crops, rationally using all the factors affecting it. One of these factors is the timely and sufficient application of mineral fertilizers, the cost of which largely determines the size of the cost of production. The emergence of precision farming is associated, first of all, with the improvement of all types of agricultural machinery and technologies, as well as with the rapid development of computer technology, methods of computer modeling and information technology. The integrating basis of the technology is geographic information systems that allow registering and processing information characterizing the state of soil and crops. This information makes it possible to effectively use one of the most significant resources in crop production - mineral fertilizers.
