Vermicompost of the toxic and allelopathic weed parthenium () was explored for its possible use as an organic fertilizer. Replicated plant growth trials were conducted using four levels of parthenium vermicompost (0, 2.5, 3.75, and 5 t/ha) to assess their effects on the germination, growth, and fruition of a typical food plant ladies finger (). Additionally the role of vermicompost in reducing plant pests and disease was evaluated.
Vermicompost encouraged the germination and growth of ladies finger at all levels of vermicompost application, with best results obtained in 5 t/ha treatments. The positive impact extended up to the fruit yield. Vermicompost application also improved the quality of fruits in terms of mineral, protein, and carbohydrate contents, and reduced the disease incidence and pest attacks.
The studies establish the fact that parthenium acquires all the qualities of a good organic fertilizer with concomitant loss of its toxic and allelopathic properties after it gets vermicomposted. The findings raise the prospects of economical and eco-friendly utilization of billions of tons of parthenium biomass which is generated annually but goes to waste at present.
对有毒且具有化感作用的杂草银胶菊的蚯蚓堆肥进行了研究，探讨其作为有机肥料的潜在用途。使用四个水平的银胶菊蚯蚓堆肥（0、2.5、3.75和5吨/公顷）进行了重复的植物生长试验，以评估它们对典型食用植物秋葵种子萌发、生长和结果的影响。此外，还评估了蚯蚓堆肥在减少植物病虫害方面的作用。
在所有蚯蚓堆肥施用量水平下，蚯蚓堆肥均促进了秋葵种子的萌发和生长，在5吨/公顷处理中获得了最佳效果。这种积极影响一直延伸到果实产量。施用蚯蚓堆肥还提高了果实的矿物质、蛋白质和碳水化合物含量，降低了发病率和虫害。
研究证实了这样一个事实，即银胶菊经过蚯蚓堆肥处理后，具备了优质有机肥料的所有特性，同时失去了其毒性和化感特性。这些发现为每年产生但目前被浪费的数十亿吨银胶菊生物质的经济和生态友好利用带来了希望。
