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