The aim of the study was to analyze the state and productivity of winter wheat variety Kamyshanka 6 in the system of forest belts in the conditions of the Lower Volga region by the phases of development. The characteristics of its growth functions depend on the conditions of moisture (in the form of precipitation) over a four-year period. The research was carried out in the land use “Gorodishchenskoye” cadastral number 34:03:000000:6. The experiment and related observations were carried out according to the method generally accepted in agroforestry. Studies have shown that under the protection of forest belts by the time of sowing spring barley, the accumulation of productive moisture reserves in the 0-100 m soil layer is greater than in open space, and vice versa, at the time of sowing winter wheat, the supply of productive moisture in the open space is greater than in the forest belt. Analysis of the data shows that the lowest hydraulic technical coefficient occurs in the summer period (July - August) in almost all years of research. The most productive accumulation of precipitation was in 2016, where the HTC was 0.7, and in the other years, the HTC is varying from 0.3 to 0.5 characterizing them as dry. Structural (biometric) analysis of winter wheat showed that the highest yield was at a distance of 10H (H - height of the forest strip) and was 3.0 t/ha for winter wheat. The coefficient of correlation of winter wheat by factors X (the reserve of soil moisture in the soil layer 0-30 cm, the reserve of soil moisture in the soil layer 0-100 cm, the hydrothermal coefficient, precipitation, average daily temperature, average daily humidity, water consumption) showed that the high dependence of winter wheat yield from reserves of productive moisture R2– 0,7***0,9.
