Wheat (Triticum aestivum L.) is a major staple crop, and its sustainable productivity depends on balanced use of NPK along with eco-friendly and organic inputs to maintain soil health and avoid nutrient deficiencies caused by excessive chemical use. A field experiment was conducted at the Krishi Vigyan Kendra Bamanwara farm during the rabi season 2025-26 to evaluate the activity of earthworms on different substrates (FYM, Crop residues and kitchen waste) and its effect on the growth of wheat (Triticum aestivum L.) A total 8 treatments of different organic substrates were used for to record the activity of earthworms @ 3000 earthworms per bed was released on same time. The prepared vermicompost were applied in the field conditions with three replications. The maximum activity of earthworms was recorded in T₁ (100 % cow dung) followed by T₃ (Cow Dung + Buffalo Dung) and T₂ (100% Buffalo Dung). The lowest activity was recorded T₅ (Buffalo Dung + Crop Residues) and T₄ (Cow Dung + Crop Residues) after the Control (100 % FYM). The results revealed that the maximum growth of plants in terms of plant height, no. of tillers and biological yields was maximum in T₁ (100 % cow dung) followed by T₃ (Cow Dung + Buffalo Dung) and T₂ (100% Buffalo Dung) while lowest plant growth was recorded in T₅ (Buffalo Dung + Crop Residues) and T₄ (Cow Dung + Crop Residues) after the Control (100 % FYM).  Percent increase in the grain yield over the control was 40.91 in T1 (100 % cow dung).
