-Intercropping can increment crop development and yield because of assets use effectively. The reason for this exploration was decides the correlation of expected dry matter yield and conveying limit of monoculture land and intercropping place that is known for tree legume Indigofera (Li) and tropical grass Brachiaria (Bg). This experiment was conducted using Completely Randomized Design (CRD) with four treatment mix of establishing space as follows: Li, with planting areas of 1.00 m by 1.50 m and 1.00 m by 1.50 m, and Bg, with planting areas of 0.25 m by 0.25 m and 0.25 m by 0.50 m. Data were analyzed using analysis of variance and HSD test. The variables measured were comparison potential dry matter yield, carrying capacity and advantage for monculture and intercropping. The results showed that treatment were significant different (P<0.01) on potential yield, potential carrying capacity and advantage based on carrying capacity. The HSD test showed that intercropping Li with planting space at 1.00 m x 1.00 m and Bg with planting space at 0.25 m x 0.25 m have highest potential yield and carrying capacity, but Li with planting space at 1.00 m x 1.50 m and Bg with planting space at 0.25 m x 0.50 m have highest advantage based on carrying capacity. It conclusion that intercropping Li with planting space at 1.00 m x 1.50 m and Bg with planting space at 0.25 m x 0.50 m have most suitable for advantage based on carrying capacity.
