Abstract

A field experiment was conducted at Agriculture College Farm, Raichur, Karnataka (India) with three pigeonpea genotypes and five planting geometries during kharif, season of 2007. The seed yield and husk yield differs significantly among the three pigeonpea genotypes. The seed yield and husk yield produced by genotypes BSMR 736 (1447 kg ha-1 and 1052 kg ha1, respectively) and ICPL 87119 (1368 kg ha-1 and 992 kg ha-1, respectively) were found to be significantly higher than the seed yield (1259 kg ha-1 and 901 kg ha-1, respectively) obtained by ICPL 8863. The extent of reduction in seed yield by ICPL 8863 was 15 and 9 per cent when compared to BSMR 736 and ICPL 87119, respectively. Among different genotypes nitrogen availability was significantly superior with ICPL 8863 (217.93 kg/ha). The available nitrogen content in soil after harvest of pigeonpea decreased with decrease in row spacing from 150 x 90 cm (218.75 kg/ha) to 90×10 cm (202.04 kg/ha). The net return (19,491 ha-1) and benefit cost (B:C) ratio (2.02) were found to be significantly higher in BSMR 736. Among different Planting geometry 90×20 cm recorded significantly higher seed yield and net returns (1637 kg ha-1 and Rs. 23,085 ha-1) was on par with 150×30 cm spacing (1621 kg ha-1 and Rs. 23,018 ha1, respectively). Significantly higher B:C ratio was observed with 150×30 cm spacing (2.41)
