The study was conducted at a farmer's field in Danuman West, Sta. Maria , Ilocos Sur [Philippines] to determine the yield performance of sweet corn as affected by the intercropping of different legumes and to determine the highest net returns of legumes as intercrops of corn. The legumes used as intercrops were: mungbean, rice bean, cowpea (Black cowpea) and peanut (Spanish Red) T1-sweet corn intercropped with cowpea and t4-sweet corn intercropped with peanut and a control (To-unintercropped) corn plants. All the treatment were laid in randomized complete Block Design (RCBD) with three (3) replications. Sweet corn plant farmers in the locality are strict practitioners of monoculture system of growing crops. Taking into consideration the cultural management practices for sweet corn, the planting of each crop like mungbean, rice bean, cowpea and peanut might fit well. Thus, they derive their farm income mainly for corn. The use of intercrops in corn farming will in a way maximize the economic use of corn farms. This means an increase in farm income derived from the economic yield of intercrops; thus increasing farm income through additional crop yield from the same piece of land. Results showed no effect of legumes intercrops on sweet corn plant and yield performance. Although the highest actual sweet corn yield was recorded in the intercropped sweet 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 corn yield of 6.9 kg/plot and 28.0 kg/plot of peanuts. Intercropping gives a possibility of increasing the economic yield of sweet corn land with little modifications on the sweet corn farming techniques and practices at the farmers level.
