Abstract

The native aromatical flora of the Amazônia comes being white of some basic studies. One of these species is the Cyperus articulatus L, known as phphoca, pertaining to the Ciperácea family, whose essential oil has great potential of exploration due its importance in the local farmacopéia. Phphoca is a aromatical and medicinal plant of natural occurrence in the Amazônia. It was objectified with this work to determine and to evaluate the underground production of fitomassa, essential oil and the accumulation of macronuthents in this species, ground with and without the calcareous rock addition, using itself four doses of each one of the three studied sources of organic substance in protecting environment. The experimental delineation block-type was entirely casualizado, with four repetitions, in a factohal of type 2 x4 x3, perfazendo 96 experimental parcels. To the six months the plantation had after been endorsement gone the following parameters: weight of hzoma, oil production, production of dry substance of the root and texts of macronuthents. The aviária bed was presented as the best organic seasoning source in relation to the pie of mamona and esterco of cattle in the tested concentrations. The biggest essential oil production occurred when it applied dosages 2(330g) and 3 (440g) of aviária bed and in ground with the calcareous rock addition.
