Research results indicated significant variation in all the vegetative growth attributes and yield parameters in different drip irrigation and mulches. The maximum number of branches per vine, length of vine, number of leaves per vine and leaf area were recorded with ETc as compared to other drip irrigation treatments at 60, 90 DAT and harvest. However, in respect to earliness . days to first flowering, fruiting and harvesting were also observed with the treatment ETc. | Effect of irrigation levels and mulch on growth and yield of cucumber (Cucumis sativus L.) under poly house
