摘要：The study of the problem of the influence of climatic factors on the conditions of formation of productivity of agrocenoses has important ecological and national economic value as the estimation of dynamics of productivity of the main crops of Ukraine according to change of meteorological factors is especially actual in the conditions of global climate changes.The correlation dependence of the formation of the yield of potato tubers on the climatic factors of the western forest-steppe of Ukraine has been analyzed. Te features of the formation of potato yields depending on the amount of active temperatures, the amount of precipitation during the growing season of the crop and the reserves of productive moisture in the arable (0-30 cm) soil layer in the budding phase and during the harvesting of the crop have been established.
