| Summary: | The effects of cattle manure vermicompost on the growth and productivity of cymbidium (Cymbidium sp.)
plants were evaluated under shade conditions. Cymbidium was grown in a container medium including
50% pumice, 30% charcoal, 10% vermiculite and 10% peat moss, which was basic plant growth medium
substituted with 10%, 20%, 30% and 40% (by volume) vermicompost. The control consisted of container
medium alone without vermicompost. Plants were supplied regularly with a complete mineral nutrient
solution. The greatest vegetative growth resulted from substitution of container medium with 30% and
40% vermicompost, and the lowest growth was in the potting mixtures containing 0% vermicompost.
Most flower buds and inflorescences occurred in the potting mixture containing 30% and 40%
vermicompost, and the greatest length of inflorescences was observed in 30% vermicompost. Cymbidium
grown in a container medium substituted with 30% and 40% had the most and greatest number of flowers.
Some of the cymbidium growth and productivity enhancement, resulting from substitution of container
medium with vermicompost, may be explained by nutritional factors; however, other factors, such as
plant- growth-regulators and humates, might have also been involved since all plants were supplied
regularly with all required nutrients. |
