The article presents the results of research on the effect of different drip irrigation rates on the productivity of wine grape cultivars Bayan Shirey, Rkatsiteli and Rangdor. The experiments were conducted during 2023–2025 at the experimental fields of the Academician M. Mirzaev Research Institute of Horticulture, Viticulture and Winemaking. Drip irrigation rates of 200, 300, 400, 500 and 600 m³/ha were applied, with seasonal water consumption ranging from 800 to 2400 m³/ha. The influence of irrigation rates on cluster weight, yield per vine and total yield was evaluated. The results showed that drip irrigation significantly increased productivity indicators in all studied cultivars. The highest yield values were obtained at the irrigation rate of 400 m³/ha (seasonal water consumption of 1600 m³/ha), reaching 340.0 c/ha in Bayan Shirey, 286.0 c/ha in Rkatsiteli and 265.0 c/ha in Rangdor. It was established that this irrigation rate ensures efficient water use and provides high and stable grape yields.
