Abstract
The study was conducted at a farmer's field in Danuman West, Sta. Maria, llocos Sur to determine the yield performance of sweet corn as affected by the intercropping of different legumes and to determine the highest net returns oaf legumes as intercrops of corn. The legumes used as intercrops were: mungbean, rice bean, copea (Bluck cowpea), and peanut (Spanish Red), Thus the treatments were: T-sweet corn intercropped with mungbean, T-sweetcorn intercrapped with rice bean, T-sweet corn intercropped with cowpea, and T-sweet corn intercropped with peanut. These including a control (CG,-unintercropped corn plants) were laid out following a Complete Randomized Design (CRD) with three (3) replications. Results showed no effect of legume intercrops on corn plant height and yield performance. Although the highest actual corn yield was recorded in the unintercropped corn plants with 7.3 kg/plot, the yield performance of the farmland can be increased by intercropping different legumes with sweet corn. T4 (sweet corn intercropped with peanut) had a cornyield of 6.9 kg/plot and 28.0 kg/plot of eanuts. Intercropping gives a possibility of increasing the economic yield of the cornlands with little modifications on the cornfarming techniques and practices at thefarmer's level.
