Were prepared the technical coefficients of priprioca (Cyperus articulatus) production in three areas suppliers partner of Natura, situated around Belem, Eastern Amazon. For preparation of technical coefficients of priprioca production, the cost items and activities that comprise the growing, harvesting and processing were collected and classified as: Inputs, Services, Equipment, and Others. The details of these activities and the value of the items were obtained and constructed in situ, together with the farmers. Information used in this study considered the production of one tonne of priprioca root cultivated annually in seven plots of 60 m² (1,2 m wide x 50 m length) 0,20 x 0,20 m, in an organic system average yield of 2,5 kg m2 -1. The results describe the materials consumed, the time of manpower to carry out the operations and costs, based on local realities. Were conclude with this work that the preparation of the technical coefficient production helps farmers to estimate the cost of production and highlights the activities that can contribute to profit, for example, good manufacturing practices.
