In field experiments during two successive seasons (2003-2004 and 2004-2005), the effects of biofertilization on growth, fruit yield, and oil composition of fennel plants were investigated. Application of biofertilizer, which was a mixture of Azotobacter chroococcum, Azospirillum liboferum, and Bacillus megatherium applied with chemical fertilizers (only 50% of the recommended dosage ofNPK) increased vegetative growth (plant height, number of branches, and herb fresh and dry weight per plant… Expand

Tables from this paper

From the results, it can be concluded that the combination of full dose of NPK+biofertilizer increased plant height, fresh and dry weights of herb (g/plant) as well as seed index, and the highest mean values yield per plant and per feddan was produced. Expand
