An investigation was carried out at the Malancha Farm under Srinekatan, Shantinekatan Development Authority, Government of West Bengal, Bolepur, Birbhum, West Bengal on 4-year-old vines of Pusa Navrangplanted at 2 m × 3 m on Y-trellis to know the effects of method and interval of irrigation on growth dynamics, yield and fruit quality. There were 6-irrigation treatments, viz., basin irrigation @ 16 t/vine daily, 1-day interval, 2-day interval; drip irrigation @ 16 l/vine daily, 1-day interval and 2-day interval. Drip irrigation at one dayinterval resulted in highest yield increment (33.3%) with higher bunch and berry weight and better fruit quality. Regarding irrigation strategy, vines should be irrigated daily after pruning to 2-leaf stage, 1-day interval fromflowering to near fruit maturity and 2-day interval during fruit maturity for better growth dynamics, fruit yieldand fruit quality.
