Abstract

The article presents research materials on the impact of shelterbelts on the growth and development of spring barley. It has been established that the reserves of productive moisture on the inter-strip cell are distributed unevenly and vary depending on the distance from the forest belt. The greatest spring moisture reserve (in the conditions of agroforestry) accumulates in the zone from 5H to 15N from forest shelter belts. The yield of spring barley in the inter-strip space is formed depending on the distance to the forest belt. The distance from the forest belt and its influence on the phases of plant development has been critically evaluated based on mathematical modeling and empirical data. Data on the average daily moisture consumption of barley plants by development phases have been processed to clarify the factors affecting the formation of the crop. Functional relationships have been obtained using STATICTIKA computer program. High correlation between the distance from the forest belt and the phases of barley has been found: tube forming (R = -0.94), booting stage (R = -0.93), blooming period (R = -0.93). The forecast for barley development in the phases of grain filling and ripening is slightly lower and amounted to R = -0.89. The relationship between the coefficient of water consumption and the distance from the forest belt has not been identified. The analysis has showed the influence of the barley water consumption coefficient depending on the distance to the forest belts on the vegetation phases of this crop. The results of the study indicate the important role of forest belts
