Abstract:
In sugarcane the experiment consisted of improved water management technology (drip irrigation once in 3 days at 80 per cent PE, fertigation of N and K (275 kg ha-1 and 112.5 kg ha-1) in 14 equal splits, with 15 days interval from 15 DAP) and conventional method (0.75 IW/CPE ratio). In banana, consisted of improved water management technology (drip irrigation once in 3 days, application of entire P (35 g plant-1) at 3rd month through band placement, fertigation of N (110 g plant-1) and K (330 g plant-1) in 30 equal splits from 6th week to 35th week after planting and conventional method (1.0 IW/CPE ratio). The results of this study revealed that drip fertigation recorded lower water use of 1601 mm and higher WUE of 78.1 kg hamm-1and 26.3 per cent water saving. The higher yield of sugarcane 125.4 tonnes ha-1 was recorded in drip fertigation technology which was 35.8 per cent higher than conventional method. The B:C ratio (2.35) was higher in drip fertigation treatment compared to conventional method. In banana, drip fertigation recorded lower water use of 1650 mm and higher WUE of 12.1 kg hamm-1and 26.3 per cent water saving. The higher yield of banana 20.0 tonnes ha-1 was recorded in drip fertigation technology which was 26.4 per cent higher than conventional method. The B:C ratio (4.97) was higher in drip fertigation treatment compared to conventional method.
