Vermiculture in Egypt: - FAO - Regional Office for the Near East and

Over the past three years, a comprehensive research program on vermicomposting has
been developed at the Ohio State University. This has included experiments
investigating the effects of vermicomposts on the germination, growth, flowering, and
fruiting of vegetable plants such as bell peppers and tomatoes, as well as on a wide
range of flowering plants including petunias, marigolds, bachelor‟s button,
chrysanthemums, impatiens, sunflowers, and poinsettias. A consistent trend in all
these growth trials has been that the best plant growth responses, with all needed
nutrients supplied, occurred when vermicomposts constituted a relatively small
proportion (10% to 20%) of the total volume of the container medium mixture, with
greater proportions of vermicomposts in the plant growth medium not always
improving plant growth. Some of the plant growth responses in horticultural container
media, substituted with a range of dilutions of vermicomposts, were similar to those
reported when composts were used instead (Atiyeh et al., 2000).
