Cultivation technology elements influence on the harvest structure and quality of crops products

Topicality and methodology. The purpose of our research was to study the influence of the type of crop rotation, methods of basic land cultivation and fertilizers on the elements of winter wheat yield structure, spring barley and sugar beet and their qualitative characteristics. The studies were carried out on typical medium-thick low-humus heavy loamy chernozem on loess-like soil in the conditions of the Belgorod region. In The maximum increase in the indicators of crop yield structure was recorded on the organo-mineral fertilization system. With the cultivation of barley and winter wheat in a crop rotation, the quality of grain increases. When growing beets in crop rotation, there is a tendency to a decrease in sugar content in comparison with grain-row crop rotation, while the sugar yield increases. The organo-mineral fertilization system reduces the starch content in the grain of barley by an average of 2.4% in the crop rotation and 1.3% in the grain crop rotation compared to the control, and increases the protein content in the grain of winter wheat by an average of 1.4%. The sugar content of beets on the organo- mineral fertilization system decreases on average by 0.8%, while the sugar yield, on the contrary, increases. Land cultivation methods in most cases do not affect the technological qualities of crops.
