Vermicomposting of terrestrial weeds Lantana camara L. and Parthenium hysterophorus L.: agriculture solid waste.
The objective of this study was to determine the feasibility of vermicomposting of two noxious terrestrial weeds Lantana camara L. and Parthenium hysterophorus L. A plastic crate was used to design a compost pit and both weeds were mixed in the 1:1 ratio. Five different concentrations of weed mixture and cow dung were prepared and Eisenia fetida (Savigny, 1826) was used for vermicomposting. Physicochemical parameters of samples were analysed after 45, 60 and 90 days. Several physicochemical characteristics, important in terms of fertility, were measured in all treatments. A decrease in pH, conductivity and total organic carbon was observed in all experimental pits during the 90-day cycle. An increase in the concentration of total nitrogen, potassium, sodium, and phosphorus was also observed. The results indicated that Parthenium and Lantana can be used as raw material along with cow dung for vermicomposting.
