چکیده انگلیسی
Water hyacinth is well known for accumulating heavy metals from the water bodies and its uncontrolled growth; due to which it is posing serious threat to the water bodies and the environment. Therefore, the present paper aimed at the safe treatment and recycling of nutrients by vermicomposting of water hyacinth. Three different earthworm species E. fetida, E. eugeniae, P. excavatus were compared for its higher biomass growth, organic matter degradation and heavy metal changes during the study. The nutrient concentration and stability parameters (OUR and CO2 evolution) were evaluated during the degradation of water hyacinth in five different trials. Results showed that nutrients (Na, K, Ca, Mg, total Nitrogen (TN) and available Phosphorous (AP)) were increased and the stability parameters were reduced significantly at the end of vermicomposting. It was observed that E. eugeniae accumulated higher concentration of heavy metals in its body tissue during transit of waste through worm's gut. On an overall, E. fetida proved to be the best on account of biomass increment as well as juveniles hatched when compared with the other earthworm species during the treatment.
