Abstract
A field experiment was conducted at the Research Farm of Agricultural College, Raichur with three pigeonpea genotypes, two planting geometries and two nutrient levels under rainfed conditions during 2013-14. The results revealed that the differences in seed yield differed significantly among the three pigeonpea genotypes. The seed yield produced by genotype GRG-811 (1726 kg ha-1) was found to be significantly higher than the seed yield produced by ICP-8863(1502 kg ha-1), which was on par with TS-3R (1616 kg ha-1). The extent of reduction in seed yield by ICP-8863 and TS-3R was fifteen and seven per cent when compared with GRG-811, respectively. The net returns (Rs. 46905 ha-1) and BC ratio(2.94) were found to be significantly higher for GRG-811 as compared with ICP-8863 (` 38250 ha-1 and 2.43) and it was on par with TS-3R (` 42637 ha-1 and 2.59), respectively. Among different combinations, the spacing 90 x 30 cm and nutrient level NP 125% of the recommended dose recorded significantly higher seed yield (1693 kg ha-1) and net returns (` 46198 ha-1) when compared with all other combinations of spacing and nutrient levels viz., 60 x 30 cm with 100 per cent NP (1566 kg ha-1 and ` 39239 ha-1), 60 x 30 cm with 125 per cent NP (1576 kg ha-1 and ` 40845 ha-1) and was on par with 90 x 30 cm + 100 per cent NP (1625 kg ha-1 and ` 44107 ha-1), respectively.
