Abstract
An experiment was conducted during the rainy season of 3 consecutive years from 2000 to 2002 at the Live- stock Research Centre of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, to study the effect of row ratio of fodder sorghum [Sorghum bicolor (L.) Moench] in pigeonpea [Cajanus cajan (L.) Millsp.] intercropping systems. Intercropping of fodder sorghum in narrow row space of pigeonpea (75 cm) with a row ratio of 1:2 recorded the highest pigeonpea-equivalent yield (34.36 qlha), net returns (Rs 30,179/ha), benefit : cost ratio (4.96), aggressivity index (0.533), area-time equivalent ratio (1.21), land-equivalent ratio (1.583) and relative crowding co-efficient (15.07).Thus, the intercropping system may be adopted for higher net return, benefit: cost ra- tio and pegionpea-equivalent yield.
