Vermicompost has beneficial effects on plant growth. However, vermicompost increases electrical conductivity in soil due to increased salinity associated with continued usage. An experiment was conducted to determine effects of 0 and 7 Mt·ha−1 of cow manure vermicompost, 7 Mt·ha−1 of vermicompost leachate, or vermicompost leachate with vermiwash and a no-fertilization control on French dwarf bean (Phaseolus vulgaris L.) yield and development. Type of vermi-fertilizer affected all measured characteristics except individual pod fresh and dry weights. Plants treated with vermiwash had the tallest plants, longest pods, number of pods per plant, number of lateral branches, and number of pods, but the highest plant dry weight and longest internodes were from plants treated with vermicompost leachate. Vermiwash combined with vermicompost leachate negatively affected vegetative characteristics and yield. With leaching, the negative effects of vermicompost related to high electrical conductivity decreased and continuous application of this material may be possible. Vermicompost leachate and vermiwash can be used as fertilizer for sustainable bean cultivation.
