An experiment was conducted during 2002-03 in Jorhat, Assam, India to investigate the effect of conventional, pitcher, bamboo drip irrigation with or without polyethylene mulch on fruit yield and water-use efficiency of Assam lemon (C. limon). The fruit yields under the 3 types of drip combined with polyethylene mulch were at par (20.31, 21.26 and 20.91 tonnes/ha, respectively), however, it increased significantly compared with the drip without mulch and the control. Similarly, the highest water-use efficiency of 1.563 tonnes/ha-cm was recorded in pitcher drip with mulch, followed by bamboo drip (1.555 tonnes/ha-cm) and conventional drip (1.442 tonnes/ha-cm) with polyethylene mulch; the lowest was recorded in the control (0.445 tonne/ha-cm).
