Abstract:
The research seeks to offer a sustainable solution for managing water hyacinth
infestations while simultaneously producing a valuable resource in the form of
manure compost. The successful implementation of this approach can have
significant implication for mitigating the adverse effects of invasive aquatic plants,
improving soil fertility and fostering a more environmentally friendly approach to
waste management and agriculture. Composting of WH with cowdung (CD) was
done to produce a nutrient rich organic soil amendment. Composting of WH with
CD was done at four combinations (WH:CD, 1:0, 1:1, 1:3 and 3:1). Prepared
compost was analyzed for maturity as well as nutrient elements. Experiment was
carried out to assess the effect of compost on germination and growth promotion of
chili. Optimum electric conductivity (4.46 mS/cm
-1
), bulk density (0.47 g cm
) and
germination index (93.34) were observed in T
3
where WH:CD ration was 1:3.
Organic carbon, P, K and Na content was higher in WH compost amended with CD.
WH in combination with CM (WH:CD, 1:3) may be efficiently used through
composting. Application of CD amended with WH compost at 10 t-ha.
yielded
optimum seedling establishment, plant growth and development.
