A field experiment was conducted to study the “Drip irrigation levels on pigeon pea based intercropping systems with pulses in Malaprabha command area” under a vertisol at the Irrigation Water Management Research Centre, Belvatagi Dharwad during kharif2017. The experiment was laid out under strip plot design with three replications, comprising treatments of two drip irrigations levels (70 % and 50 % PE) and three intercropping systems viz., pigeon pea + green gram (1:3) and black gram (1:3) and sole pigeon pea along with rainfed sole pigeon pea (control). Drip irrigation provided at 70 per cent PE recorded higher pigeon pea seed yield (2,010 kg ha-1) compared to at 50 per cent PE (1,997 kg ha-1). Among the intercropping systems, sole pigeon pea under drip recorded higher seed yield (2,126 kg ha-1) followed by pigeon pea intercropped with blackgram or greengram at 1:3 row ratio (1,986 and 1,898kgha-1, respectively). Interaction effect of drip irrigation at 70 per cent PE with sole pigeon pea recorded higher seed yield (2,198 kg ha-1) followed by drip irrigation at 50 per cent PE with sole pigeon pea (2,053 kg ha-1) and pigeonpea intercropped with blackgram at 1:3 rowratio (2,047kgha-1). Rainfed sole pigeon pea recorded lower seed yield (1,613 kg ha-1). Irrespective of drip irrigation level of 50 or 70 per cent PE, pigeonpea + blackgram or greengram at 1:3 row intercropping system recorded significantly higher pigeon pea seed equivalent yield (3,412 and 3,421 kg ha-1, respectively). Higher water use efficiency was recorded under drip irrigation provided at 50 percent PE in pigeonpea intercropped with greengram (1:3) (5.48kgha-1-mm) and lower was with rainfed sole pigeonpea (3.06kgha-1 -mm).
