Abstract

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.

Highlights

Precipitation is an important climatic resource for the formation of soil moisture reserves that affect plant growth
A comprehensive analysis of the influence of climatic factors made it possible to establish that there is a strong relationship between the studied factors and the yield of potato tubers
Of particular importance are the reserves of soil moisture in the arable soil layer (0-30 cm) in the budding phase of potatoes, namely during the period of mass tuber formation, which was confirmed by our research

Summary

Introduction

Precipitation is an important climatic resource for the formation of soil moisture reserves that affect plant growth. That is why sufficient reserves of productive moisture for use by plants during the growing season are an important indicator and factor in increasing yields [1, 2]. Temperature rise is reflected in all climatic indicators. Based on this variable, there is a clear trend of thermal elongation of the growing season, its beginning is noticeable, the number of days with a minimum temperature below 0 ° C decreases, and the number of days with a maximum temperature above 25 ° C increases;. The developed perspective models are approved, which predicted some increase in the amount of winter precipitation and their decrease in the summer period by the end of the century. Our analysis of the manifestation of climate change, which has already been recorded in Ukraine, showed that:
