The present investigation entitled Scheduling of irrigation in cauliflower (Brassica oleracea var. botrytis L.) under mid hill conditions of Himachal Pradesh was conducted during 2011-12 and 2012-13 at the experimental farm of Department of Soil Science and Water Management, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni- Solan, H.P. The experiment was laid out in Randomized Block Design with eight treatments and three replications i.e. 3 cm irrigation at IW/CPE ratio i.e. 1.0 (T1), 0.8 (T2) and 0.6 (T3); at 0.4 (T4), 0.5 (T5) bar tensiometric suction; at 25 (T6) and 50 (T7) per cent depletion of available water in 0-30 cm depth; farmer’s practice (T8) i.e. 5 cm irrigation at 12-15 days interval depending upon the rainfall). The irrigation schedules had significant effect on crop growth and productivity of cauliflower under T1, T4 and T6 irrigation treatments. The crop yield increased by, 29.5, 30.1 and 32.2 per cent over T3 and 25.5 and 26.0 and 28.1 per cent over T8 irrigation schedule. Schedule T1 required less quantity of irrigation water (18.9 cm and 21.9 cm) compared to T6 (30.9 cm and 36.9 cm) and T4 (27.9 cm and 33.9 cm) without any significant reduction in yield and gave higher WUE and B:C ratio. Thus, all these three schedules were equally good. Keeping in view the productivity, WUE and B:C ratio, T1 irrigation schedule was found efficient and economical.
