Management of Indigofera tinctoria as a natural dye produces organic waste that has not been utilized. One of the proper management of organic waste is to process it into organic fertilizer. This study aims to examine the role of organic fertilizer waste Indigofera tinctoria and mycorrhizae on the growth and yield of Indigofera tinctoria. The study used a completely factorial randomized block design with two factors, namely organic waste fertilizer and mycorrhizae. The results showed that organic fertilizers and mycorrhizae had no effect on the net assimilation rate and the number of leaves. Organic fertilizer has a significant effect on the biomass and fresh weight of the crown. Mycorrhizal effect on plant fresh weight and the percentage of roots infected with mycorrhizae. Mycorrhizal inoculation 20g/plant showed 51.33% infected roots. The combination of 200 g. plant-1 organic fertilizer and 10 g. plant-1 mycorrhizal fertilizer increased 84.04% the number of root nodules. The number of root nodules was positively correlated with the percentage of roots infected with mycorrhizae.
