Methodological approach to grain yield planning

Abstract

The global problems of mankind, especially in recent decades, have an increasing impact on the agrarian sphere of activity of any country, including Russia. In modern conditions, the strategic goals outlined for increasing the productivity and sustainability of agricultural production in the agricultural sector of the country should be solved comprehensively within the framework of adaptive landscape farming, taking into account specific soil-climatic, organizational, economic, environmental and other factors. The concept of “maximum possible grain yield” will always change upward with increasing intensification of agriculture, maintaining soil fertility, creating and introducing highly productive varieties, using a mineral nutrition system, as well as means of protection against pests and diseases, etc. The article establishes the conditions under which it is necessary to focus on obtaining the planned yield, the dependence of the possible yield on the utilization factor of photosynthetic activity and radiation for the growing season is provided. Based on the determination of the yield, a set of measures and techniques is developed to obtain a planned crop and an organization chart is proposed on the problem of planning grains. According to the results of the research, the dependence of the crop cost on the level of optimal planning is provided.
