In the present study, cow dung, saw dust, and blended soil were taken for (manure) biofertilizer production through vermicomposting (Eisenia fetida) experimental method. This work reports with the results of E. fetida in the mixture of blended soil, cow dung, and saw dust in different ratios for 60-day compost experimental trial. In all the experimental sets, the pH levels were not changed. The nitrogen content was changed in highest levels as 0.025% in B1, B2, B3, B4, and A4 experiments. The maximum phosphorous content was noted as 33.77% in B3 and 29.11% in A4, and the maximum potassium level was noted 33.77% in B3. The total organic carbon (TOC) levels were renowned at premier level, and slight changes of electrical conductivity were noted in all experimental sets. Nitrogen, phosphorous, and potassium contents were recorded high level as 1:3:3 and 1:4:4 ratios of composed agro and cattle waste mixture on the 45th and 60th days. The present study was clearly showed and suggested that the vermicomposting technology is an exchange, renewable, and cheap cost technology for the production of good quality eco-friendly fertilizers for plants if mixed with blended soil, cow dung, and saw dust in the ratio of 1:4:4.

在本研究中，牛粪、锯末和混合土壤通过蚯蚓堆肥（Eisenia fetida）实验方法用于（粪便）生物肥料生产。这项工作报告了E. fetida的结果在混合土壤、牛粪和锯末不同比例的混合物中进行 60 天的堆肥试验试验。在所有实验组中，pH 值都没有改变。在 B1、B2、B3、B4 和 A4 实验中，氮含量的最高水平变化为 0.025%。B3 中磷含量最高为 33.77%，A4 中为 29.11%，B3 中钾含量最高为 33.77%。总有机碳 (TOC) 水平以一流水平着称，并且在所有实验组中都注意到电导率的轻微变化。氮、磷和钾的含量在第 45 天和第 60 天被记录为高水平，农业和牛粪混合物的比例为 1:3:3 和 1:4:4。本研究清楚地表明，蚯蚓堆肥技术是一种可交换、可再生、
