The objective of this work was to evaluate the effect of doses of bovine bone meal on the productive and morphological characteristics of Panicum maximum cv. Mombasa in two cuts (60 and 90 days after seeding) at a height of 10 cm. At which one can conclude based on the dry mass of the aerial part, there the dose of bovine bone flour that provided maximum productivity in grass Mombaça was for satisfy 160 mg/dm³ of P2O5. And its use in of doses below 80 mg/dm³ of P2O5 did not favored the increase of dry mass of root at the grass Mombaça.
