摘要

Vermicomposting has drawn interest as a sustainable substitute for conventional organic farming because of its low energy needs and ability to use renewable energy sources. The present study reveals the use of earthworm Perionyx excavates along with decomposed dry hay, red loamy soil, and cow manure in vermicomposting for enhancing the agricultural productivity. The pH was maintained from 7.7 ± 0.045 to 7.75 ± 0.105 over a period of three-week, moisture content from 523.5 ± 08.43 mg/g to 527.6 ± 08.30 mg/g, and humus content from 472.3 ± 12.05 mg/g to 478.5 ± 10.50 mg/g. The total nitrogen was found to be 2.1%, total phosphorus of 0.56%, and total potassium of 0.69 in the formulated vermicompost. Additionally, it measures the presence of 197 mg/kg manganese, 82 mg/kg zinc, and 278 mg/kg iron, alluring its worth as an organic fertilizer rich in nutrients for sustainable farming. This study also investigated the presence of glycerol, 1,3-propanediol, and dimethyl silane diol using Gas Chromatography-Mass Spectrometry (GC-MS). Glycerol, known to mount up the composting temperature, hence improving the soil moisture retention, and enhancing plant growth and stress tolerance whereas the presence of dimethyl silane diol was identified as a potential plant growth promoter. The plant grown in formulated vermicompost when compared with a control, and commercially available vermicompost, reveals potent growth in Brassica rapa showing 27 elongated, broadly open and leaves compared to just 21 in the control group. The current study suggest that Perionyx excavatus-based vermicomposting can effectively enhance plant growth, offering a sustainable, environmentally friendly alternative to traditional fertilizers.
