Abstract
Vermicomposting could be a suitable technology for the transformation of different waste into available products. Vermicompost industry is the based on earthworm. Although, there are more than 7000 species of earthworm in the word, but Eisenia foetida is one of the most important for soil fertility. Of course, several studies showed which earthworms the variety of activities such as healthy food as well as in medicine. The aim of this study was to assess, the influence of different waste such as vegetable, paper, banana, carrot, bread wastes on the growth and development of E. foetida. The effect of various wastes on growth, reproduction and adult's weight of an earthworm E. foetida was studied under identical laboratory conditions. In the use of banana peel, flour and paper filings baby number from 500 has risen in 2000, 1800 and 1500 respectively. The maximum amount of vermicomposted soil compared with controls, were related to the paper filings and lettuce (145 and 106 g respectively). Generally the earthworm population, weight of adults and the amount of soil vermicompost, showed that paper filings and banana peel were the best medium for earthworm E. foetida.
