Abstract
The transition to a new reference period of 1991–2020 requires updating the estimates of agroclimatic resources in agricultural regions. The paper summarizes the results of the annual monitoring of agroclimatic conditions over 1961–1990 and 1991–2020 obtained by both the statistical analysis and the Climate–Soil–Yield simulation system and provides their comparative evaluation. It has been noted that along with growing aridity of the most fertile areas of the steppe and forest-steppe zones, there is an almost universal growth of spring precipitation, which compensates to some extent the negative impact of high summer temperatures on the yield. A significant decrease in the climate-driven productivity of spring wheat from the period of 1961–1990 to the new reference period of 1991–2020 has been revealed for the main grain-producing regions. Estimates of productivity trends for major grain crops, spring and winter wheat, are given in connection with climate change and the development of agricultural technologies. Estimates of changes in the wintering indices and sown areas for winter wheat are also given.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
