Abstract

In order to investigate the influence of different level of vermicompost and NPK fertilizer fertilizers on yield, growth parameters and essential oil of fennel (Foeniculum vulgare Miller.), an experiment based on complete randomized blocks design with six treatments and three replications at Galogah, in 2012 and 2013 season was carried out. Treatments included NPK fertilizer, vermicompost (5, 10, 15 and 20 t/ha) and control. Analysis of variance showed that plant height, number of main and lateral branches, number of umbrella per plant, number of umbelets per umbrella, seed yield, biological yield, harvest index and the amount of oil produced at different levels of vermicompost and NPK fertilizer statistically significant. Generally results indicated that using 15 t/ha vermicompostshowed more positive effect on recorded traits of fennel (Foeniculum vulgare) than other treatments.DOI: http://dx.doi.org/10.3126/ijls.v9i4.12673
