With the help of generalization and mathematical processing of statistical data, the author found that in Kursk Region, the yield of spring wheat from 1995 to 2018 increased more than 2.5 times (from 1.58 metric tons / ha in 1995 to 3.97 metric tons / ha in 2018), although in Russia there were no significant changes in crop yield. While conducting a correlation analysis of the associated data of spring wheat yield in Kursk Region for the period studied, a close relationship was established with the application of basic nutrients (0.84) and with the prevailing weather conditions of a particular year of cultivation (0.86). It was found out that spring wheat grew under optimal weather conditions in 50% of cases. Adverse and favorable weather conditions are formed equally in 25 % of cases of years. Under optimal weather conditions, a high direct linear relationship between yield and the sum of active temperatures is recorded, which is significant at 99% level. Crop shortage in unfavorable years was associated with high air temperature during the entire growing season of the crop and a lack of humidity from seedlings to grain ripeness and an increase in humidity during the harvest of the crop. A linear regression relationship between yield and moisture coefficient was revealed. Thus, the moisture coefficient is the limiting agro-climatic resource of spring wheat yield under the conditions of Kursk Region.
