Annotation

Under the conditions of growing crops, climatic factors are of essential importance as they directly affect the course of processes in the ecosystem. Climatic conditions of the Forest-Steppe zone are characterized by relatively mild winters, moderately humid and warm summers. Such conditions are especially favorable for the formation of high productivity of spring barley in agrocenoses, even under the global climate change. considering the conditions of global climate change, the study of peculiarities of formation of the spring barley yield depending on the climatic conditions of the western Forest-Steppe of Ukraine is of ecological and practical significance.

The aim of the research is to evaluate the effect of temperatures and precipitation during the vegetation period on the level of spring barley yield. To do this, the following task was set, particularly to systematize weather factors over the years of research in accordance with the biological properties of the culture; to make analysis of barley yield; to formulate mathematical equations of the dependence of productivity on the specified factors.

The correlation between spring barley yield formation and climatic factors of the western Forest-Steppe of Ukraine was analyzed. The dependence of spring barley yield on the sum of active temperatures and the amount of precipitation during the growing season was studied.

Evaluation of the relationships between the spring barley productivity, the sum of active temperatures and the amount of precipitation shows the dependence between those factors (R2 = 0.838 – the sum of active temperatures, R2 = 0.892 – the amount of precipitation).

The regression equations showed a significant effect of the rainfall and sum of temperatures during growing season in the formation of the spring barley yield.
