Agricultural degradation areas are increasing worldwide. From them, 56% due to water erosion, 28% due to wind erosion, 12% due to soil nutrient depletion, salinization, pollution processes, and 4% due to densification, swamping, and subsidence processes. As a result of such negative processes and the existence of the water shortage problem in 80 countries of the world, 7 million hectares of arable land are withdrawn from agricultural use every year, and the problem of food security is arising in the world. In this article, the results of scientific research and cost-effectiveness calculations on 3 different slopes of cultivated fields on soils prone to irrigation erosion are written. In Uzbekistan, great attention is paid to solving the problems of improving land reclamation and increasing the productivity of irrigated lands. In the Action Strategy for the further development of the Republic of Uzbekistan in 2017-2021, it is stated that “... further improvement of the reclamation condition of irrigated lands, development of the network of reclamation and irrigation facilities, wide introduction of intensive methods of agricultural production, first of all, modern water and resource-saving agrotechnologies, highly productive tasks on the use of agricultural machinery” are defined. It is necessary to develop new technologies for effective methods of increasing the productivity of lands prone to irrigation erosion in order to implement part of the specified tasks.
In the conditions of Fergana region, Bukhara-8, Sultan and S-8290 cotton varieties were planted in six terms, and 11-12, 12-13, 13-14 cotton branches were chemically ginned by hand. The results of the variant with the highest yield Bukhara-8 cotton variety sown on April 20-25 and pruning on 12-13 harvest branches are given.
Мамлакатимиздагина эмас балки ер шарида асосий озиқ-овқат экини хисобланган буғдой донини етиштириш маданияти такомиллашиб бормоқда. Мустақиллик йилларида Республикамиз ҳудудларининг иқлим шароитига мослашган буғдой навлари яратилди, етишитириш агротехнологиялари такомиллаштирилди. Шунга қарамасдан табиатдаги салбий холатлар жазирама иссиқ, қурғоқчилик аксинча сув босиши, шамол (қатиқ сел, ёмғир дўл) кутилмаган (минус, плюс) хароратларнинг таъсиридан истисно тариқасида экилган буғдой бошоқларидан табиий холда анғизга тўкилиб исроф бўлаётган буғдой донинг сони ва салмоғини аниқлаш мақоланинг асосий мақсади қилиб олинган.
