Ricebean and Frenchbean being non-conventional crops in the peninsular region an experiment was conducted to evaluate the possibility of growing these legumes and their suitability for intercropping with predominant cereal, maize in 1:1 and 1: 2 row proportions alongwith recommended check maize + soybean at Main Agricultural Research Station, Dharwad representing Northern transitional zone of Karnataka. Intercropping of maize + frenchbean grown in 1:2 row proportion produced higher maize equivalent yield (8068 kg ha-1) and assured more income (Rs. 29 054/- ha-1) while, ricebean was comparable to maize + soybean in productivity. Maize + soybean had significantly higher protein output (851 kg ha-1) than other systems. Intercropping of grain legumes also ensured better utilization of resources viz., land, soil moisture, nutrients and light.
