Field experiment was conducted during 2011-2015 at Sisal Research Station (22.041°N, 84.295°E, 267 m above mean sea level, AMSL), Bamra, Odisha, India to study the effect of drip-irrigation and micronutrients (Zn and B) on growth, fibre yield, water use efficiency, nutrient and micronutrient content in sisal (Agave sisalana Perr. Ex Engelm.). It was observed that interaction of drip-irrigation @ 4 l/hr for 2 hrs at 2 weeks interval during 14-23 standard meteorological week (SMW) x micronutrients (zinc sulphate @ 20 kg + borax 15 kg/ha) produced the longest leaf (97.2.cm) and produced the maximum number of leaves (139.87 x 103) in sisal. The maximum fibre yield was recorded either with drip-irrigation @ 4 l/ha for 4 hrs at 2 weeks interval during 14-23 SMW together with zinc sulphate 20 kg/ha + borax 15 kg/ha (1546 kg/ha), or with drip-irrigation @ 4 l/hr for 2 hrs at 2 weeks interval during 14-23 SMW together with zinc sulphate 20 kg/ha + borax 15 kg/ha (1493 kg/ha). Application of micronutrients (zinc sulphate 20 kg + borax 15 kg/ha) together with drip-irrigation (4 l/hr for 2 hours at 2 weeks interval during 14-23 SMW) gave the highest water use efficiency (4.52 kg/ha-mm). Water use efficiency reduced if the drip-irrigation (4 l/hr at 2 weeks interval during 14-23 SMW) was prolonged for 4 hours (3.46 kg/ha-mm). The highest Zn content (19.3 ppm) was recorded in treatments where zinc sulphate (@ 20 kg/ha) together with borax (@ 15 kg/ha) was applied to soil. Similarly the highest B content (14.4 ppm) was also observed in zinc sulphate (@ 20 kg/ha) + borax (@ 15 kg/ha) applied cases.
