The objective of the research was to develop scientific and methodological bases for
adapting the technology of growing winter wheat depending on weather conditions in early
spring. Winter wheat was grown at different sowing dates. It is established that the reserves of
productive moisture in the soil at the time of renewal of spring vegetation are crucial for the
formation of winter wheat harvest. After worse forecrop, the impact of moisture on productivity
reaches 49.7–66.4%. The later the renewal of spring vegetation of winter wheat is, the lower the
productivity of the crops. The shorter the period from the date of transition of the average daily
air temperature above 0 °C to the beginning of active vegetation of plants is, the higher the
productivity of winter wheat crops. Therefore, depending on weather conditions of early spring
period and the time of renewal of spring vegetation of plants, it is necessary to adjust the
technology of growing winter wheat during the spring-summer period.
