The results of the analysis of long-term trends in changes in individual climatic characteristics and variations in weather conditions of the growing season in the forest-meadow zone of the Middle Urals for the period from 1958 to 2020 are presented, their influence on the choice of hybrids and some elements of corn cultivation technology are estimated. As a result of calculating the linear trend, a statistically proven trend has been established to increase the sum of active temperatures above 10 °C for May – September. At the same time, random fluctuations of the analyzed parameters over the years have a direct impact on corn development and productivity, and the limiting factor is the lower limit of these fluctuations, the values of which increase throughout the analyzed period. Nevertheless, the variation over the years remains strong, and the lower limit of these fluctuations does not reach the minimum level for the stable maturation of early-maturing corn hybrids. Therefore, for the conditions of the Middle Urals, the previous recommendations concerning the selection of corn hybrids for early maturity, cold resistance and drought resistance remain relevant. At the same time, the revealed climatic trend allows to predict an increase in the probability of obtaining feed with a high content of exchange energy, which characterizes it as positive one.
