The article describes agricultural technologies increasing nitrate nitrogen content in the soil, crop yield, protein content and its fractional composition in winter wheat grain in the Middle Volga region. An economic and energy assessment of the effectiveness of winter wheat cultivation is provided for various predecessors, methods of primary tillage and fertilizing. Long-term studies were carried out on the fields of the Department of Agriculture, the laboratory “Agroecology” of Samara State Agricultural Academy. When cultivating winter wheat using the black fallow method, without autumn mechanical tillage with double application of nitrogen fertilizing, the highest yield indicators (2.79 t/ha), protein content of 13.12 %, the maximum net income, profitability of 92 % and energy efficiency were achieved. The energy efficiency coefficient in crops was the largest with the lowest energy coefficient in proteins.

Due to the complex production process, its block model simplified for practical purposes is presented for winter wheat. The model allows for predicting the yield and providing recommendations on the optimal fertilizer application, quality, nature and quantity of fertilizers. The interconnections and interdependences of the production process values were studied on the basis of the long-term experiment on winter wheat cultivation using the method of correlation analysis. The yield and protein values can be used individually and in combination based on the requirements for the production process of winter wheat in the Middle Volga region.

The aim of the research was to study the influence peculiarities of different levels of nitrogen nutrition on the activity of peptide hydrolases and protein content in ontogeny of barley plants.The paper discusses the content of total nitrogen, protein and the dynamics of activity of proteolytic enzymes during ontogenesis of barley plants. The activity of peptide hydrolases, the content of protein and total nitrogen were determined in four developmental phases in the flag leaf and forming caryopses of barley. The aim of the work was to determine the effect of different levels of nitrogen on the quantitative content of protein, the total amount of nitrogen, as well as on the activity of acidic and neutral peptide hydrolases. In the course of the research, the following features were revealed: 1. The content of total nitrogen and protein, as well as the activity of proteases, depended on the developmental phase and on the level of nitrogen nutrition; 2. Increasing doses of nitrogen contribute to a greater nitrogen outflow from flag leaves into the forming grain; 3. High nitrogen norms inhibit the activity of peptide hydrolases. 4. The highest rates of activity of acidic proteases were noted in the phase of full ripeness. 5. The total activity of peptide hydrolases increased in variants with a twoand three-fold nitrogen dose.
