Abstract:

To evaluate drip fertigation in banana at farmers holdings, On Farm Experiment under Operational Research Project on improved water management technologies in Banana were conducted in farmers fields one each at head, middle and tail reaches of  Kugalur distributory of Lower Bhavani Project canal command areas during 2016 and 2017. The experiment 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). Drip irrigation laterals were laid with 180 cm lateral spacing and 0.6 m lateral spacing and banana were planted with spacing of 1.8 x 1.8 m (triangular geometry planting). The discharge rate of the dripper was 4 lph and the irrigation was given once in three days and fertigation of N -110 g plant-1 and K -330 g plant-1 in 30 equal splits was given from 6-35th week after planting. The results of this study revealed that drip fertigation recorded lower water use of 1650 mm and higher WUE of   12.1 kg hamm-1 and 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. Drip irrigation once in 3 days and 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 recorded lower water use, higher WUE, yield and economics in banana.
