Abstract

The experiment was conducted in and area of organic cultivation of the Sector of Olericulture of the Experimental Station of the University Campus of Gurupi, Universidade Federal do Tocantins – UFT (Federal University of Tocantins), located in the south latitude 11º 43’ 45” and west longitude 49º 04’ 07” with average height of 280 m. It was evaluated the effect of the organic fertilization over phytotechnical aspects in three chemotypes of Lippia alba (Mill.) N. E. Brown (chemotypes I: myrcene-citral; II: citral-limonene and III: carvone-limonene). The experiment was factorial (3 x 4) in a randomized block design with three replications [(three chemotypes and four doses of organic fertilizer (0, 2, 4 and 6 kg m-2)]. The plots were formed by ten plants. The characteristics evaluated were: plant height, number of leaves, number of main branches, fresh and dry matter of leaves, yield of fresh and dry leaf matter. The chemotype III compared to the others was noteworthy. The fertilization rates provided a linear increase in mean traits of plants. The dose of 4 kg m-2 of organic tanned cattle manure is most suitable for the three chemotypes.
