Mapping of the right-bank part of Сherkasy region water consumption by corn for grain

Abstract

The article examines one of the directions of mapping for an administrative entity using the example of creating cartograms of the average multi-year total water consumption of corn per grain by interphase periods of development. The purpose of the article is to create cartograms of corn water consumption per grain by interphase periods for the right-bank part of the Cherkasy region. In this study, based on empirical information for a 30-year period (1991–2020) and its analysis, the calculation of the average multi-year total water consumption of corn per grain by interphase periods was carried out. The total water consumption of the studied culture for separate interphase periods was determined by the water balance method. On the basis of the calculated values of water consumption, cartograms of the average multi-year total water consumption (mm) of corn per grain by interphase periods for the right-bank part of the Cherkasy region were compiled and generalized. Cartograms of the average multi-year total water consumption of corn per grain by interphase periods were compiled by the method of isolines, which were obtained by interpolation at the sampling points. As a result, information on individual meteorological stations was approximated for the entire studied territory. For agricultural formations of various forms of ownership of the right-bank part of the Cherkasy region, the information presented on the cartograms can be used to identify factors that affect the water consumption of corn for grain in interphase periods or to carry out appropriate differentiated agrotechnical and meliorational measures necessary to achieve the planned yield.
