Presowing tillage allows you to lay a solid foundation for friendly and healthy seedlings, as well as a high crop of crops. For its implementation, a whole range of work is required to prepare the soil, which is carried out by plows, cultivators, harrows, and other agricultural machines and implements.
In the soil and climatic conditions of Uzbekistan, soil preparation for cotton sowing is carried out in the spring, on autumn plowing, while depending on the state of the field, differentiated fields are cultivated: partial planning, subsurface cultivation, chiseling, cultivation, harrowing with praying. At the same time, the composition of the soil prepared for sowing does not always meet the required quality of the structural-aggregate composition, the soil becomes coarse, and the top soil layer is very compacted. This situation prevents the high-quality implementation of the technological process of sowing cotton seeds of a cotton seeder.
One solution to this issue is the active loosening of the soil in the area of cotton seeds with simultaneous sowing on one unit.
In the complex of measures aimed at reducing the laboriousness of cultivating and growing high yields of raw cotton, a major role is given to further improving the technology and means of mechanizing cotton sowing. In recent years, rainy weather has been observed during the period of sowing cotton, as a result of which the germination of cotton seeds is significantly delayed. When showers, puddles form on the traces of the seeder, which leads to rotting of the seeds, as a result of which repeated sowing is carried out. When cultivating cotton on the ridges, in accordance with the theoretical foundations of soil cultivation, a favorable composition of the arable layer is ensured for a long period of cotton growing. This contributes to friendly shoots, good plant development and a high yield of raw cotton with early ripening, moisture accumulation on the ridges eliminates soil pollination, destruction of the structure, and formation of soil crust. Using the drip irrigation system allows to provide plants with water and fertilizers, where necessary, at the right time and in the right amount.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
