Evaluating the Changes in Quantities and Types of Substrates Containing Organic Wastes on the Growth and Reproduction of the Earthworm (Eisenia fetida)

Background: The feasibility of converting organic wastes into vermicompost and the effect adding such substrate on growth reproduction earthworm (Eisenia fetida) were investigated in present study through a two-factor factorial experiment with completely randomized design triplicate. Methods: first factor nine different treatment combinations included control; potato (P); carrot pulp (C); vegetables (V); sawdust (S); potato, vegetables, (PVC); sawdust, (SPC); (VSP); pulp, (CVPS). second was related to two amounts 100 150 g. This research carried out using analysis basket trials Tonekabon County, Mazandaran Province, Iran, 2021. base earthworms animal manure positioned boxes washed urban tap water reach pH value between 6.5 7. After ripening vermicompost, emptied, worms counted. Results: variance showed significant difference number cocoons studied treatments (P<0.1), but there no groups. maximum (mean=605) corresponded combination (S), minimum (mean=185) found vegetable (V). Conclusion: bed provided optimal conditions for E. fetida.
