Evaluation of sprinkler irrigation efficiency for the “Mirzoyi Kizil” carrot variety in the Tashkent region

This study evaluates the efficiency of sprinkler irrigation technology for the "Mirzoyi Kizil" carrot variety under the agro-climatic conditions of the Tashkent region. Field experiments were conducted during 2023-2025 at the experimental station of "TIIAME" National Research University in the Urta-Chirchik district. The study compared sprinkler irrigation with traditional furrow irrigation by assessing irrigation regime, application intensity, seasonal water consumption, water productivity, and carrot yield. Sprinkler irrigation was applied at a rainfall intensity of 0.4 mm min -1 to provide uniform water distribution and reduce irrigation losses. The results showed that sprinkler irrigation improved both water-saving performance and crop productivity compared with furrow irrigation. Seasonal irrigation water use decreased by up to 32.2%, while carrot yield increased by approximately 22%. These findings indicate that sprinkler irrigation is an effective water-saving technology for carrot cultivation on typical grey soils of the Tashkent region. The study confirms the practical importance of optimizing sprinkler irrigation parameters to improve vegetable crop productivity and support sustainable agricultural development under conditions of increasing water scarcity in Uzbekistan.
