A field experiment was conducted at Agricultural Research Station, Malnoor,  University of  Agricultural Sciences,  Raichur on vertisols during kharif seasons of 2010-11 and 2011-12 to study the productive potential of pigeonpea genotypes in different planting geometry under protective irrigation. The experiment consisted of three genotypes (BSMR-736, TS-3R and Laksmi) and seven planting geometry ( 90 x 20 cm, 120 x20 cm, 120 x 60 cm, 120 x 90 cm, 150 x 20 cm, 150 x 60 cm and 150 x 90 cm).  The experiment was conducted in split plot design with three replications.  Results revealed that among three genotypes tested,  BSMR-736 (1667 kg/ha) recorded significantly higher grain yield  over Laksmi (1369 kg/ha)  and  TS-3R (823 kg/ha).  With respect to  planting geometry, 90 x 20 cm, 120x20 cm and  150x20 cm recorded the highest grain yield, net returns and B:C  irrespective of the genotypes.  The interaction between genotypes and planting geometry showed that  the genotype BSMR-736 planted at 150X20 cm recorded the highest grain yield (2322 kg/ha),  net returns (Rs. 64421/ha) and B:C (4.37).
