Currently it has been observed the need for alternative botanical sources to meet the demand of potato starch manufacturers, mainly in the period between crops that the industry is idle. In Mato Grosso do Sul arrowroot can become an alternative source to meet this seen demand for the extraction of starch using the same physical structure already installed, and its starch has high commercial value because of its peculiar features required both in the market national and international, but to reintroduce that grow in the field of these agro-industries requires a better knowledge of nutrition to better understand your needs regarding macronutrients and micronutrients for its development, this work focused on checking the phosphorus doses of contribution to production arrowroot rhizomes. They evaluated several plant points such as diameter, mass shoots, root mass, shoot dry weight, root dry mass and mass of the rhizomes. It was found that the doses of P significantly influenced culture, it was observed that the higher dose of P of all varieties had greater weight of the plant with emphasis on the dose 320 kg ha-1 , in which the plants had an average weight 1.29 kg.
