A field experiment was conducted during the Kharif season of 2015 at College of Agriculture, Shivamogga to study the effect of maize +pole bean/ French bean intercropping on crop productivity, system productivity and economics. The experiment consisted of ten treatments in combination of three row spacing for maize; 60 cm and 75/45 cm for paired row with intra row spacing of 30 cm for both sole and inter crop of maize with pole bean, 90 cm x 20 cm for maize intercropped with French bean. Recommended spacing of 120 cm x 30 cm for pole bean under sole and intercropping treatments; Two times of sowing of pole bean i.e. simultaneously with maize and 10 DAS of maize; two levels of fertilizers for pole bean viz., 100 per cent and 50 per cent of RDF. Among the treatments, maize sole crop at 60 cm x 30 cm spacing and sole crop of pole bean at 120 cm x 30 cm spacing recorded significantly higher grain yield of 83.01 q ha-1 and fresh bean of 102 q ha-1 respectively, over the intercropping treatments. Significantly higher MEY was obtained under maize + pole bean simultaneous sowing under paired row at 75/45 cm x 30 cm spacing (174.55 q ha-1) along with the higher net returns (130331.9 Rs. ha-1).
