Abstract
To maintain the pace of the agriculture industry and assist bridge the gap between food supply and demand, best-implemented, sustainable, and optimal solutions are needed. Soil and water resources, research and development, extension, agricultural education, and related infrastructure development must be prioritized to boost food production and enhance soil and water management. Research has been carried out on the effect of various methods of main tillage - chiseling with various types of chisel rippers and moldboard plowing - on the agro- and water-physical parameters of light chestnut soil. Differences in soil density and moisture levels have influenced the development of corn plants. On the variants with deep chisel tillage, the accumulation of dry and raw plant biomass and the yield of corn grain were higher. Thus, the methods of main tillage allow to regulate the agro- and water-physical state of the soil and to have a significant effect on the productivity of plants. On the basis of the data obtained, for high-quality main tillage, providing optimal indicators of its density, crumbling, reserves of total and available moisture in the soil, it is possible to recommend the use of an experimental chisel ripper CR-2.4.
