The ginger culture was planted in Espirito Santo State on a commercial scale for just over 10 years as an alternative income for farmers family based submitted high yield potential, but requires studies to their best advantage due to the great variability of climatic conditions of the State. The aim of this study was to evaluate the yield of fresh rhizomes, the dry mass of leaves and rhizomes and the extraction and accumulation of N, P and K of the culture depending on the application of increasing doses of P, in a dystrophic Ultisol . The experiment was conducted on a farm in the municipality of Santa Maria de Jetibá (ES) between the months of August 2006 and June 2007. Experimental model adopted was randomized blocks with four treatments and four replications. The treatments consisted of control (no P fertilization), and doses of 60, 120 and 240 kg ha - 1 of P 2 O 5 applied at planting. The plants showed continuous growth up to 180 days after planting (DAP) and the phase of the plant where there was greater uptake of N, P and K in the flowering cycle was at 240 DAP. Analy- zing the contents of N, P and K, in the rhizome and leaves over the cultivation cycle, it was observed that, in general, most of the accumulation occurred in the rhizome.
