The article analyzes the effectiveness of mechanization of cotton irrigation through furrows in the Asht district of the Sogd region of the Republic of Tajikistan. An economic and environmental analysis of irrigation technique for through furrows was carried out. Observations showed that labor costs when using tubular outlets are on average 30.3 % less than with conventional irrigation technology, compliance with agrotechnical rules of cultivation, timely irrigation provided an increase in potato harvest by 6–22 % in two years and cotton up to 7 % The cost of water per unit of crop with an improved technology for planning water use and irrigation using tubular outlets was 13–48 % less compared to conventional technology. The effectiveness of furrow irrigation in dekhkan farms is ensured by improving the design of water distributors. For this, a design of a tubular water outlet-water meter with removable fittings has been developed.
