Summary : A two-cropping study on the influence of corn and legumes (mungbean and peanut) on crop productivity and soil erosion on hilly land was conducted in an area with 31 percent slope in Campangga, Barili, Cebu in May 1984 - January 1985. The effects of corn 'IPB Var 1,' mungbean 'Pagasa 3,' and peanut 'UPL-Pn2' planted as monocrops or as intercrops in 1:1 and 2:2 row planting combinations were evaluated. A randomized complete block design with three replications was used. During the wet season, mungbean had poor growth and low pod setting. Peanut was viny, had low pod formation and yielded lower than the dry season planting (first cropping). Productivity per unit area of intercropping was generally higher than the monoculture check. Corn intercropped with mungbean in a 2:2 row planting pattern gave the highest land equivalent ratio (LER) of 1.62 during the first cropping, followed by 1:1 corn + mungbean and 1:1 corn + peanut with LER of 1.41 and 1.29, respectively.
