ABSTRACT
The field experiment was conducted during 2014 and 2015 to assess the water use efficiencies and economics of various drip irrigation systems like surface drip irrigation with mulching, surface drip irrigation without mulching and subsurface drip irrigation with each system having three sub treatment, viz. 80 100 and 120 per cent ET using drip irrigation The water use efficiency (WUE) varied from season to season. For first season (WUE) varied from 18.71 kg/m3 (80 per cent ET) of surface drip irrigation with mulching (T1I1) to 8.10 kg/m3 (120 per cent ET) of subsurface drip irrigation (T3I3) and same trend followed in the second seasons. The highest B: C ratio was found in 80 per cent ET (5.21) of surface drip irrigation with mulching (T1I1) and the lowest B: C ratio was found in 120 per cent ET (4.26) with subsurface drip irrigation (T3I3) and same trend followed in second season. In both season highest yield was recorded in the 80 per cent ET of surface drip irrigation with mulching than the other treatments.
Key words: Watermelon, Irrigation, Efficiency, Economics.
