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 black gram or green gram at 1:3 row ratio (1,986 and 1,898 kg ha-1, respectively). Interaction effect of drip irrigation at 70 per cent PE with sole pigeon recorded higher seed yield (2,198 kg ha-1) followed by drip irrigation at 50 per cent PE with sole pigeon (2,053 kg ha-1) and pigeon pea intercropped with black gram at 1:3 row ratio (2,047 kg ha-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, pigeon pea + black gram or green gram at 1:3 row intercropping system recorded significantly higher pigeon pea seed equivalent yield (3,412 and 3,421 kg ha-1, respectively) and system net returns ( 1,11,195 and 1,09,309 ha-1, respectively). Higher water use efficiency was recorded under drip irrigation provided at 50 per cent PE in pigeon pea intercropped with green gram (1:3) (5.48 kg ha-1 -mm) and lower was with rainfed sole pigeon pea (3.06 kg ha-1 -mm).EnglishThesis
