The article presents the results of the reconstruction of the yield of grain crops of the economy of the Volchikhinsky district of the Altai Territory (south of Western Siberia) on the basis of an extended tree-ring chronology until 1822. Based on the restored series, the cyclical nature of cereal productivity was analyzed. In particular, the 22-, 25-, and 27-year cycles are highlighted as the most significant. The increase in the amplitude of variability of the yield series was noted by year from the middle of the 19th century to the end of the 20th century.
