We studied the thickness (80000, 100000 and 120000 hectares also 7,2;9,0 and 10,8 plants per 1 mph,nrespektively), soil moisture of the field in two different regimes irrigation (70-70-60 and 75-75-60 % as well as irrigation procedures 2-3-0 and 2-4-0, respectively) and the ratio of fertilizer in two principles (1:0,7:0,5 and 1:1:0,5). Annual fertilizers are: N200 P140 ва K100 and N200 Р200 ва К100 kilograms. The irrigation regime is bassed on the fakt that the yield of cotton grovn under 70-70-60% of the ChDNS hugher than the yield of the variaunts irrigated on the 75-75-60 regime. At 70-70-60% irrigation mode, depending on the thickness of the bush and the fertilizer ration, on average yield of 35,4-40,5c/ha is abtained, 75-75-60% the yield in cultivation varied by an average of 33,5-36,5e/s. Experience shows that the micronaire index of the fibers is higher in the irrigation mode of 70-70-60 % than the fiber which consists of 4,3-4,5 micronaire and irrigation of 75-75-60 %.

According to the statistics agency of Uzbekistan, the number of vehicles running on an internal combustion engine will be more than 3.2 million in 2023. 74% of them run on compressed natural gas, 24% run on gasoline, and 2% run on electricity and other alternative fuels. Potential customers for tuning hybridization of used cars are cars running on gasoline, and in addition, the economic efficiency of tuning hybridization can be considered in vehicles running on compressed natural gas.
