Reference crop evapotranspiration (ET0) value was calculated based of Penman–Monteith method, which was recorded the maximum value during July. Actual evapotranspiration (ETa) started to increase from the date of sowing till Midseason stage and became maximum in July and August then again reduced in the last Maturity and harvest stage in September. The crop coefficient (Kc) values decreased by an average of 35% due to use drip irrigation with mulch. The percent of water use reduction was 65%, 64% and 57% for the transparent mulched drip irrigation, black mulched drip irrigation and no mulch drip irrigation, respectively compared to the furrow surface irrigation treatment.
