EFFECT OF ORGANIC AND CHEMICAL FERTILIZATION ON GROWTH, YIELD, AND ESSENTIAL OIL CONTENT OF FENNEL (Foeniculum vulgare Mill.)
Year: 2012
Type: article
Abstract: Two field experiments were carried out at a private farm at South Ghor area, Al-Karak, Jordan, during 2009/2010 and 2010/2011 cropping seasons.The study aimed to find the effect of four levels of organic fertilizer manure at 0, 20,40 and 60 ton/ha and three levels of chemical fertilizer at 0, 30, and 60 kg/ha on growth, yield, and essential oil percentage of fennel (Foeniculum vulgare Mill.).The experimental design was complete randomized block design with split plot arrangement with three replications.The results showed that organic manure application combined with chemical fertilizers (NPK+ trace elements) significantly (P<0.01)increased plant height, number of branches, fresh and dry weights of herb, essential oil (%) in fennel fruits, and essential oil yield/plant, as compared to pure chemical fertilizer treatments.Herb nitrogen and potassium contents were significantly (P<0.01)increased with organic fertilizer amendment or chemical fertilizer application , whereas herb-phosphorus content was not significantly affected by all fertilizer treatments.Soil electrical conductivity (EC) and organic matter content increased significantly by adding organic manure, while soil pH was not affected.
