Abstract
The results of research on determining the technological parameters of regulating the soil water regime when functioning drainage systems (drainage and irrigation system "Romen", local contour water-accumulating systems - CWAS) of the Left-Bank Forest-Steppe are presented. Priority crops on drained lands (Sumy region) are corn for grain (share in the sown area 35%), sunflower (20%), wheat (16%), soybean (14%) and rapeseed (4%). Weather conditions on research and production plots (State Enterprise "Nadiya" and LLC Agrofirma "Lan") during the growing season 2022–2025 were characterized by extremely uneven distribution of precipitation and significant fluctuations in air temperature. The average hydrothermal coefficient (AHC) during the growing season in 2000–2025 varied within 0,6-1,9, in 2025 it was 0,77 (the conditions of a moderately arid zone). Technological parameters for regulating the soil water regime when cultivating corn for grain, buckwheat, winter wheat, sunflower, soybeans and perennial grasses were obtained, the applying of which ensures an increase in the yield of economically attractive crops up to 25%. During long-term operation (more than 30 years) of the CWASs, the effectiveness of their functioning was confirmed, as well as the possibility of ensuring a favorable soil water regime in areas with developed microrelief, obtaining a stable crop yield and increasing the efficiency of agricultural land use in the areas with micro-depression landforms. The increase in winter wheat yield by 12% compared to the watershed and by 64% compared to micro-depressions without ameliorative measures was observed. Technological parameters for regulating the soil water regime are recommended for use by specialists in agriculture and water management (landowners and land users of drained lands, operational and project water management organizations) when governing the water regime on drained lands of the Left-Bank Forest-Steppe.
