The bamboo (Bambusa vulgaris) belongs to the poaceae family. It has its origin in China, though widely spread in the American Continent. It is suitable for reforestation due to its fast growth. In Brazil, the main utilization of this plant is for the production of cellulosic pulp for the paper industry. The present study aims at evaluating the influence of mineral fertilization of bamboo plants grown in pots with soil. The soil was fertilized with the doses equivalent at 0.00; 20.00; 40.00; 80.00 and 120.00 kg ha-1 of nitrogen and 0.00; 10.00; 40.00; 80.00 and 100.00 kg ha-1 of phosphorus and potassium. The experimental design was randomized blocks with four replications. The bamboo plants were grown for 120 days. After this period the plants were harvested and the total biomass was determined as well the biomass allocation in leaves, culm, roots and total biomass. The highest production of total dry weight biomass was achieved the dose of 120, 10 e 100 kg ha-1 de NPK. The highest biomass production in leaves, culm and root it was achieved respectively with the doses of 80, 10 and 100 kg ha-1, 120, 40 and 100 kg ha-1 and 80, 10 and 100 kg ha-1 of NPK.
