A field trial was conducted during 2001-02 at Solan, Himachal Pradesh, India using drip and basin methods of irrigation to assess the effect of different soil moisture regimes on growth, cropping and fruit quality of kiwifruit and to work out total irrigation water requirement and water use efficiency of drip method of irrigation over conventional basin method. Six irrigation treatments, i.e. drip irrigation at 100, 80 and 60% crop evapotranspiration (ETc) and basin irrigation at 20% soil moisture depletion from field capacity and at 15 days interval, were given to 15-years-old kiwifruit vines. Drip irrigation at 100% ETc gave significantly higher vine growth, yield, fruit size and weight compared with 80 and 60% ETc and basin irrigation treatments. The vines irrigated at 100% ETc with drip method registered 39 and 43% increase in shoot growth and trunk girth, respectively, over traditional basin method of irrigation. Water use efficiency was found highest (2.91 q/ha/cm) with drip irrigation at 100% ETc and lowest (1.84 q/ha/cm) with basin irrigation at 15 days interval. Besides saving 22% of irrigation water, drip irrigation at 100% ETc yielded 19.4% more compared with basin irrigation and also produced better size and quality fruits.
