The role of organic fertilizer from natural dye waste and mycorrhizal inoculation on the growth of Indigofera tinctoria L.

Abstract

Abstract Management of Indigofera tinctoria as a natural dye produces organic waste that has not been utilized. One of the proper managements of organic waste is to process it into organic fertilizer. This study examines the role of organic fertilizer waste and mycorrhizae on the growth and yield of Indigofera tinctoria. The study used a completely randomized block design with two factors: organic waste fertilizer and mycorrhizae. The results showed that organic fertilizers and mycorrhizae did not affect the net assimilation and leaf area indexes. The combination of organic fertilizers with mycorrhizae supports leaf growth. The combination of 400 g.plant−1 organic fertilizer and 10 g.plant−1 mycorrhizal fertilizer increased the number of leaves by 257%. Organic fertilizer has a significant effect on the fresh weight of the crown, fresh weight and root biomass. Organic fertilizer dose of 200 g.plant−1 increased fresh root weight, root biomass and fresh crown weight by 68.5%, 68.29% and 63.27% respectively. Mycorrhizae 10 g.plant−1 increased root length by 23.54%. Leaf growth correlated with length, fresh weight and root biomass. Organic fertilizer from the extraction of Indigofera tinctoria is an effort to achieve zero waste to support plant growth.
