An agroforestry system that integrates eucalyptus trees with agricultural crops is a promising approach to sustainable land management, combining timber production with food security objectives. The study was conducted on dry land between eucalyptus stands to increase food crop productivity. The experiment using rice husk biochar, urea fertilizer and manure aimed to maintain water and nutrient availability. This study used a three-factor complete randomized block design. The first factor was without biochar and rice husk biochar, the second factor was the ratio of urea and manure fertilizer doses (150:0, 75:10, 0:20 kgha-1:tonha-1), and the third factor was the corn monoculture planting pattern, corn + mung bean intercropping, and mung bean monoculture. The analysis was carried out using ANOVA, DMRT, and T test. This study showed that. The combination of rice husk biochar, and the ratio of urea and manure fertilizer doses (75 kg ha-1:10 ton ha-1) in the monoculture planting pattern can increase chlorophyll A content and the number of corn stomata, and the monoculture planting system can increase the width of corn stomatal aperture. The combination of the ratio of urea and manure fertilizer doses (75 kg ha-1:10 ton ha-1) and the monoculture planting system can increase the total chlorophyll content in mung beans
