Formation of grain quality spring wheat in the field crop rotation crop rotations depending on predecessors and chemicals

The article presents the results of research on the influence of crop rotation on the yield of spring wheat in crop rotation crop rotations. The research was conducted in prolonged hospital experience in crop rotations over the past eight rotations. Experiments laid by a method of the split parts. Studied a possible alternative fallow as the predecessor of the spring wheat, while analyzing the structure of crop and evaluation of product quality. Recommendations are given on optimization of the structure of sown areas, farmers of the region. These materials can be used in the design of field crop rotations, with the aim of increasing the efficiency of production in conditions of forest-steppe of Western Siberia.
