Resumo

To support rural extension activities for family farming in the western Amazon, we evaluated the production of Mombasa grass (Panicum maximum Jacq) as a function of phosphorus sources (single superphosphate and calcined bone meal) and rates (100, 200, and 400 kg ha-1 P2O5). The experimental design was a randomized complete block, in a 2x3+1 factorial scheme. The use of calcined bone meal yielded a dry matter (1.73 t ha-1 cutting-1) and a plant height (55 cm) higher than the control (1.03 t ha-1 cutting-1 and 35 cm, respectively). How­ever, the values were lower than those obtained with single superphosphate (3.19 t ha-1 DM and 91 cm in height). Regarding the dry matter production in the experimental period (202 days, five cuttings), the calcined bone meal promoted 54% of the production obtained with the use of single superphosphate.
