Abstract: A field experiment was conducted to study “Growth, yield and economics of pigeonpea as influenced by irrigation levels and cropping systems under drip irrigation” at Zonal Agricultural Research Station, Kalaburagi, during kharif 2018-19. The experiment was laid out in split plot design with three replications. The main factors consists of irrigation levels (50%, 75% and 100% CPE) and sub factors consisting of cropping systems (Sole pigeonpea, pigeonpea + greengram (1:2), pigeonpea + blackgram (1:2) and pigeonpea + soybean (1:2). The results revealed that significantly higher growth attributes viz., plant height (176.42 cm), number of primary branches (15.04), secondary branches (16.23), leaf area (20.84 dm² plant^-1), LAI (0.58) and TDMP (306.82 g plant^-1) at harvest and yield attributes viz., number of pods per plant (241.76), pod weight per plant (191.24 g plant^-1), seed yield per plant (94.79 g plant^-1), test weight (10.22 g), grain yield (2656 kg ha^-1), stalk yield (6431 kg ha^-1) and husk yield (2485 kg ha^-1) and also higher gross returns (Rs. 226245 ha^-1), net returns (Rs. 173435 ha^-1) and BC ratio (4.29) were recorded with 75% CPE compared to 50% and 100% CPE. Among the cropping system, sole pigeonpea recorded significantly higher growth attributes viz., plant height (183.37 cm), number of primary branches per plant (9.84), number of secondary branches per plant (19.50), leaf area (25.55 dm² plant^-1), LAI (0.71) and TDMP (340.98 g plant^-1) at harvest and yield attributes viz., number of pods per plant (241.76), pod weight per plant (191.24 g plant^-1), seed yield per plant (94.79 g plant^-1), test weight (10.22 g), grain yield (2656 kg ha^-1), stalk yield (6431 kg ha^-1) and husk yield (2485 kg ha^-1) as compared to intercropped pigeonpea. While, pigeonpea + greengram (1:3) intercropping system recorded significantly higher gross returns (Rs. 252400 ha^-1), net returns (Rs. 196590 ha^-1) and BC ratio (4.52) as compared to sole pigeonpea and other cropping systems.
