Fennel ( Foeniculum vulgare Mill), which belongs to Apiaceae (Umbelliferae) family is a perennial plant. The essential oil of fennel is used to flavor different food preparations and in medicine and perfumery industries. Healthy vigorous transplants will be less susceptible to insects, diseases and transplant shock leading to better crop performance. Formulating growing mixes is especially challenging. Animal manure has a high mineral nutrient content. An experiment was conducted in a randomized complete block design with four replications to evaluate the effect of animal manure rate on growth of fennel transplants. The maximum of shoot fresh weight (164.0 mg/plant), shoot dry weight (37.5 mg/plant), root fresh weight (22.8 mg/plant) and root dry weight (4.4 mg/plant) were observed at 10% animal manure.
