ABSTRACT
The study was conducted during 2008-09 cropping season at ICRISAT, Patancheru, A.P., India, to determine the cost and economic benefits of seed production (AxR) of pigeonpea hybrid ICPH 2671. Two row ratios of 4:1 and 3:1 with seven planting distances were the treatments that served as the basis for analyzing economic returns. Production cost for each of the row spacing 75 cm and 150 cm was calculated. The current study revealed that productivity of hybrid ICPH 2671 differed significantly among planting distances, row spacings and row ratios. Planting distance at 75 cm x 30 cm in 4:1 row ratio gave the highest net returns (Rs. 224,614 ha-1) and brought in the highest cost-benefit ratio (Rs. 6.32). Likewise, the cost of producing one kilogram of hybrid seeds at 75 cm x 30 cm spacing was estimated at Rs. 7.37.
