SOUZA, M.F. et al. Liming and organic fertilization on Lippia citriodora (Kunth) phytomass and essential oil production. Rev. bras. plantas med. [online]. 2010, vol.12, n.4, pp. 401-405. ISSN 1516-0572. http://dx.doi.org/10.1590/S1516-05722010000400001.
The present work aimed to evaluate the effect of liming and bovine fertilization on Lippia citriodora Kunth phytomass and essential oil production. The experimental design was completely randomized with seven treatments (control; Ca and Mg sulfate; limestone; Ca and Mg silicate; Ca and Mg sulfate + manure; limestone + manure; Ca and Mg silicate + manure) and two harvest seasons, with four replicates. Soil adjustment showed to be a necessary procedure for Lippia citriodora development. Independently of the harvest season, fresh and dry matter yields were higher under treatments with bovine manure (32 t ha-1); however, no effect of treatments was observed on essential oil concentration.
