Parthenium hysterophorus is considered one of the most noxious terrestrial weeds which needs to be efficiently managed to sustain the environment and vermicomposting are a promising eco-friendly management technique. In the current study, vermicomposting of P. hysterophorus was carried out using a polyculture of two epigeic earthworm species, i.e., Eisenia fetida and Eudrilus eugeniae employed in five different vermireactors referred as R_p1, R_p2, R_p3, R_p4, and R_p5 with five mixing ratios 3:7, 4:6, 5:5, 6:4, and 7:3 respectively of P. hysterophorus to cow dung as a blending material. The nutrients in the final vermicompost were determined by analyzing different physico-chemical parameters and the efficiency evaluated by the growth rate of earthworms. After vermicomposting, TKN, TP, and K contents increased with the highest percentage change of 74.74%, 91%, and 47.2% respectively, compared to initial values. Reduction in C/N ratio was observed in all the vermireactors with the lowest C/N ratio of 9.76. EC increased for all the vermireactors during the process and reached in the range of 3.7–3.85 ds/m at the end of the process. The highest percentage gain in biomass of earthworms was 46.25% in R_p2. Vermicomposting of P. hysterophorus is possible for the management of this invasive weed through polyculture of the earthworms E. fetida and E. eugeniae to obtain a value-added organic fertilizer, i.e., vermicompost by a sustainable process.

银丝草被认为是最有害的陆地杂草之一，需要对其进行有效管理以维持环境，而蚯蚓堆肥是一种有前途的生态友好型管理技术。在目前的研究中， P. hysterophorus的蠕虫堆肥是使用两种表层蚯蚓的混养进行的，即Eisenia fetida和Eudrilus eugeniae ，在五个不同的蠕虫反应器中使用，称为 R _p 1、R _p 2、R _p 3、R _p 4和R _p 5，以P. hysterophorus与牛粪的5种混合比例分别为3:7、4:6、5:5、6:4和7:3作为混合材料。通过分析不同的理化参数来确定最终蚯蚓堆肥中的营养成分，并通过蚯蚓的生长速度来评估效率。蚯蚓堆肥后，与初始值相比，TKN、TP和K含量增加，百分比变化最大，分别为74.74%、91%和47.2%。在所有蠕虫反应器中都观察到 C/N 比降低，C/N 比最低为 9.76。在此过程中，所有蠕虫反应器的 EC 均有所增加，并在过程结束时达到 3.7-3.85 ds/m 的范围。 R _p 2 中蚯蚓生物量的最高百分比增益为 46.25%。通过蚯蚓E. fetida和E. eugeniae的混养，可以将P. hysterophorus进行蚯蚓堆肥，以管理这种入侵杂草，以获得增值有机肥料。 ，即通过可持续过程进行蚯蚓堆肥。
