The effectiveness of organic fertilizer from natural dyes waste on the growth of Indigofera tinctoria L.

Abstract

Indigofera tinctoria natural dye extraction waste has not been utilized become environmental pollution can encourage climate change. Climate change causes land degradation and decreased crop productivity. Management of the waste into organic fertilizer and used in plant cultivation need to mitigate climate change. This study aimed to examine the role of organic fertilizer from natural dye waste in obtaining the optimum dose in supporting the growth of Indigofera tinctoria. The study used a Randomized Completely Block Design (RCBD) with one factor, namely the dose of organic fertilizer from the extraction of Indigofera tinctoria L. with 11 levels (0 g/plant, 50 g/plant, 100 g/plant, 150 g/plant, 200 g/plant, 250 g/plant, 300 g/plant, 350 g/plant, 400 g/plant, 450 g/plant, and 500 g/plant). The results showed that the natural dye extraction waste could be used as organic fertilizer to support the growth of Indigofera tinctoria. Application of organic fertilizer at a dose of 50 g/plant showed an increase in the plant height of 14% and number of leaves by 124%. The dose of organic fertilizer of 350 g/plant is the optimum dose in producing the high number of leaves, leaf area index, and plant biomass.

Potential of Indigofera tinctoria Natural Dyes Compost on Maize Vegetative Growth

“…Indigofera tinctoria fertilizer can improve soil chemical quality. Indigofera tinctoria fertilizer dose of 350 grams/plant has been able to increase the growth and yield plants [20]. However, the content of Indigofera tinctoria compost with its application to food crops has not been carried out.…”
