Abstract

This study investigates the impact of water hyacinth (WH) bokashi applied on stockpiled topsoil from coal mining and utisols areas on maize growth and productivity. Water hyacinth, a locally abundant weed, was processed into bokashi and applied to a mixture of post-mining soil and ultisol at varying concentrations (0%, 12%, 25%, and 50% w/w). Maize plants were cultivated in these media, and growth parameters such as plant height, stem diameter, forage biomass, total biomass, and maize yield were measured weekly. The study employed a Randomized Complete Block Design (RCBD) with four treatments, each replicated four times. Results were analysed using ANOVA and Duncan's Multiple Range Test. The findings demonstrated that WH bokashi could improve the C-organic, nitrogen, P2O5, K2O, and pH levels of the cultivation medium and enhanced maize growth and biomass production. The most effective treatment was 25-50% WH bokashi, which yielded the highest maize productivity. This research highlights the potential of water hyacinth bokashi as an organic amendment for improving degraded soils and supporting sustainable agriculture on reclaimed mining lands.

Abstract

Post-mining lands in Indonesia are characterized by severely degraded soils with low fertility, high acidity, and poor water retention, posing major challenges for agricultural rehabilitation. This study investigates the effect of water hyacinth (Eichhornia crassipes) compost at varying dosages (0%, 25%, and 50%) on early vegetative growth parameters of forage maize over a 30-day period. A randomized complete block design was used with six replications per treatment. Key growth indicators—plant height, stem diameter, and their respective growth rates—were measured and statistically analyzed. Results showed that the 50% compost treatment significantly increased plant height (51.87 cm) and height growth rate (1.73 cm/day) compared to lower dosages. Stem diameter parameters, while numerically improved, did not yield statistically significant differences. The improved growth is attributed to enhanced nutrient availability, microbial activity, and water retention due to compost application. These findings confirm that compost from invasive biomass can effectively improve degraded soils and initiate early crop development. The study contributes to sustainable land reclamation strategies and emphasizes that there must be long-term assessments of compost.
