Abstract

ABSTRACT Organically based nutrient sources may provide an alternative to synthetic fertilizers to provide nutrition for plants. Vermicomposting may be able to mitigate problems with detrimental microbes, especially thermo-tolerant pathogens in conventional compost. Information is lacking on effects of vermicomposted animal manure on leafy vegetables. Vermicomposted cattle manure, in combinations with soil [0:100, 10:100, 20:100, and 30:100 (v/v)], was tested to determine how it affects growth, yield, and chemical characteristics of parsley (Petroselinum crispum Mill.) in a greenhouse. Growth and yield parameters were measured at 60 days after sowing. Results indicated that addition of vermicompost to soil increased plant height and numbers of leaves. Total yields and amounts of potassium, phosphorus, and total soluble solids were greater for parsley plants grown in the 10:100 combination.
