Vegetable corn (Super Sweet 9) plus forage legumes (Desmanthus virgatus, Clitoria ternatea, Crotolaria juncea, and Macroptilium atropurpureum) intercropping was conducted January to June 1990 dry season to evaluate the possibility of integrating forage legume with vegetable corn and identify best crop combination, in terms of yield performance of both crop used as source of food and feed animal. The experiment was conducted at the International Rice Research Institute [Los Banos, Laguna, Philippines] lowland farm under partially irrigated environment. Forage legumes were established forty days ahead of corn planting under zero tillage with aid of a drugstick. Treatments were laid out in RCB design in 3 meters x 5 meters plots replicated three times. Yield of corn was not significantly affected (P<.05) by forage legumes intercropping. Average yield of corn obtained was 1.02 tons per hectare. Monocropping vegetable corn gave a yield of 0.94 tons per hectare. Average reduction in dry matter yield of forage legumes was 21.7 per cent compared to monocropping (P<.01). In this production systems, vegetable corn + crotolaria, clitoria or desmanthus combination can serve as potential source of high quality animal feed in rice-based farming systems during dry seasons.
