This decision was made for economic advantage of potential productivity in order to choose between the got crops leguminosae Indigofera (Li) and tropical grass Brachiaria (Gb). The purpose of this consideration was to investigate the apparent magnitude of this received change in light of bearing limit and abandonment. The plan for this test was completely random, and for combination planted (Cp), it used a combination of four drugs from the planted area, Cp1: Li with dimensions of 1.0 m x 1.0 m and Gb, with dimensions of 0.5 m x 0.25 m; Cp2: Li with dimensions of 1.0 m x 1.0 m and Gb, with dimensions of 0.5 m x 0.5 m; Cp3: Li, with dimensions of 1.0 m x 1.5 m and Gb, with dimensions of 0.5 m x 0.25 m; Cp4: Li, which had 1.0 m x 1.5 m, and Gb, which had 0.5 m x 0.5 m. Using the analysis of variance and the HSD test, the data were analyzed. Economic advantage based on potential carrying capacity were the variables that were measured (P<0.01). The outcomes appeared to be substantially different. The economic benefit are highest due to the improved grain yields of intercrop in Cp4. Li covered crops with established areas of 1.0 m x 1.5 m and Gb with established areas of 0.25 m x 0.5 m may be considered to have the best advantages in terms of yield for economic advantage.
