A field experiment was conducted during the spring seasons (February-June) of 1995, 1996 and 1997 on sandy-loam soil in Almora, Uttaranchal, India to study the effect of irrigation levels in conjunction with pine needle mulch on potato (Solanum tuberosum). Pine needle mulch increased the tuber yield by 35% over no mulch. The yield significantly increased up to IW/CPE ratio of 1.50, except during 1997, which received a good rainfall (236.3 mm). The mean effect of mulch was equivalent to one irrigation (5 cm) in terms of potato yield advantage. Mulch and irrigation treatments produced a higher number of large (>50 mm) tubers compared to no mulch and rainfed treatments. The water use efficiency (WUE) was higher (39.9%) with mulch over no mulch. All irrigation treatments had higher WUE than rainfed (678 kg/ha-cm), with the highest value being recorded irrigation at the stolonization stage (830 kg/ha-cm). The canopy temperature was 25±2.5°C in IW/CPE ratio of 1.50, which recorded the highest tuber yield.
