The research was conducted at the Cagayan State University at Lal-lo from June 2017 to March 2018 to establish a CSU demonstration farm for cacao-based integrated multi- story cropping system by intercropping mungbean (Vigna radiata L.) and glutinous corn (Zea mays) during establishment stage of cacao farming and to showcase its economic potential. Specifically, it aimed to determine the following: the plant height, number of leaves, survival rate, leaf area index, plant height of glutinous corn and mungbean, pods of mungbean, length of corn ear, yield per plot(kg) and return of investment. It was laid out in Randomized Complete Block Design (RCBD) with three treatments and replicated three times. The treatments were: T1- cacao as control, T2- cacao + glutinous corn and T3- cacao + mungbean. No significant differences among the treatments on the plant height, number of leaves, and leaf area index. However, there are significant differences in terms of survival rate, plant height of glutinous corn and mungbean, pods of mungbean, length of corn ear, yield/plot (kg). Grafted cacao seedlings intercropped with glutinous corn produced highest net income and return on investment compared to mungbean. Therefore, planting cacao intercropped with glutinous corn is recommended to the Lal-lo farmers to obtain higher income during the establishment stage. Another trial must be conducted to give more conclusive results and another research must be conducted using other intercropped.
