The data will be analyzed using analysis of variance and continued with DMRT level of 5% if there is a significant difference. The result showed that the substitution of ZA fertilizer with organic fertilizer could increase the yield of red ginger cultivation and the use of organic fertilizer with 398.7 g/m2 could increasing number of leaves, number of saplings, fresh and dry straw weight, weight of fresh and storage rhizomes, and the length of rhizomes
