This study reports the results of vermicomposting with Eisenia fetida of Parthenium hysterophorus mixed with cow dung in different ratios (25%, 50% and 75%) in a 18 weeks experiment. In all the treatments, a decrease in pH, OC(total) and C:N ratio, but increase in EC, N(total), P(aval), Ca(total), K(total) and heavy metals was recorded. The cocoons production and growth rate (biomass gain worm(-1) day(-1)) were maximum in 100% cow dung. The results indicated that parthenium can be a raw material for vermicomposting if mix with cow dung in appropriate quantity.
本研究报告了在 18 周的实验中，用赤子爱胜蚓对不同比例（25%、50%和 75%）的三裂叶豚草与牛粪混合进行堆肥的结果。在所有处理中，均记录到 pH 值、OC（总）和 C:N 比下降，而 EC、N（总）、P（有效）、Ca（总）、K（总）和重金属增加。在 100%牛粪中，茧的产量和生长率（每只虫每天的生物量增益）最高。结果表明，如果将三裂叶豚草与牛粪按适当的比例混合，可以作为堆肥的原料。
