Since last few decades, fresh water availability is continuously declining against time and share of irrigation to it is also decreasing. However, under such situation we have to increase the income of the farmers. Efficient utilization of available water resources may be the best possible answer to it. Drip irrigation system is a water application method which can improve the water use efficiency. Reduction in evaporation loss through mulching also enhances water use efficiency. Considering these, a field experiment was carried out to assess sole and interactive effects of irrigation and mulch on leaf area index and fruit yield. There were four irrigation regimes viz. surface irrigation (SI) at IW/CPE=1 and three drip irrigation regimes at 1.0 ETc, 0.6 ETc and 0.8 ETc placed in main plots. Subplots were fitted with no mulch (NM), straw mulch (SM), black polyethylene mulch (BPM) and geo textile mulch (GTM). Irrespective of time highest value of LAI and yield were recorded under 1.0ETc and GTM. The same was lowest under SI and NM. LAI and yield posses’ strong relationship,R2 value increased from0.62 to 0.75 from first to third plucking period. Maximum WUE was noted under 0.6ETc-GTM combination and it was almost 10 times lower under SI-NM combination.
