Field experiment was conducted on medium black soil during Kharif 2017 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to study the performance of maize and pigeonpea under different row proportions and planting geometry under delayed onset of monsoon. The experiment was laid out in RCBD design with eleven treatments and replicated thrice. The treatments comprised of sole maize, sole pigeonpea with two genotypes (TS3R and GRG-811), two row proportions of maize and pigeonpea (2:1 and 4:2) with planting geometry of 60 x 20 cm and 75 x 20 cm for maize and 120 x 20 cm for pigeonpea. Among all treatments sole maize (98.64 q ha-1) and pigeonpea cv. TS3R and GRG -811 (16.5 and 14.9 q ha-1 respectively) recorded significantly higher grain yields over intercropping systems. Significantly higher maize equivalent yield was recorded with maize + pigeonpea cv. TS-3R (4:2) with 60 cm × 20 cm spacing (111.5 q ha-1) .Gross returns (Rs.1,35,193 ha-1), net returns (Rs.77,957 ha-1) and B:C ratio (2.4) was also higher with maize + pigeonpea cv. TS3R (2:1) with 60 x 20 cm as compared to sole crop of maize or pigeonpea and other intercropping systems.
