Abstract: A field experiment was conducted during 1995-96 and 1996-97 at Nauni (Solan) on loamy sand 'Inceptisol' to study the effect of drip irrigation and plastic mulch as compared to surface imgation on green pod yield, water use efficiency and benefit-cost ratio of pea (Pisum sativum Var. Lincoln) cultivation. The treatments comprised different irrigation levels based on pan evaporation, pan and crop factors under plastic mulch and unmulched conditions. Drip irrigation at 'V' volume of water applied gave significantly higher yield of pea (89.6 q ha -1 ) as compared to surface irrigation (59.9 q ha -1 ). Plastic mulch plus drip irrigation further raised the yield to 105.4 q ha -1 . Water use efficiency under drip irrigation alone, drip irrigation plus plastic mulch and surface irrigation was 1.88, 2.21 and 1.06 q pod/ha cm, respectively. Drip irrigation besides giving a saving of 32 per cent water resulted in 49.5 per cent higher yield as compared to surface irrigation. The benefit-cost ratio of pea cultivation under drip alone, drip plus plastic mulch and surface irrigation was 2.06, 2.11 and 1.93, respectively.
