Land between juvenile rubber rows in the rubber plantation is potential for corn farming. This research aimed to assess corn production and added value of corn farming intercropped with juvenile rubber. It also studied effect of corn intercrop on land productivity improvement and juvenile rubber growth. The experiment was conducted at the Sembawa Research Station from January until April 2016 on the juvenile rubber plantation using IRR 112 clone and spacing of 6 m x 3 m (550 tree per ha). The experiment was carried using a randomized block design (RBCD) with treatments of two planting-patterns, i.e. PT1 (rubber+corn) and PT2 (monoculture corn) with three replications, and the control was monoculture corn. The data were analyzed using ANOVA followed by DMRT at the level of 5%. Results of the research showed that corn intercropped with rubber significantly affected land productivity and IRR 112 clone growth during juvenile rubber period. Intercropped corn farm business in the juvenile rubber plantation was profitable as its R/C ratio of 1.62 at corn lower price and R/C ratio of 2.27 at corn higher price. Intercropped corn farming was profitable and it was feasible practiced inside the juvenile rubber plantation.
