The objective of this study was to evaluate the effect of combined levels of N and P in nutrient content and nutritional efficiency in seedlings of canafistula (Peltophorum dubium Spreng. Taub.) on Oxisol. The experiment was carried out in pots of 4 dm(3), with treatments arranged in 4x4 factorial scheme, four N levels (0, 20.82, 41.64 and 62.46 mg kg(-1) N) and four P levels (0, 41.72, 83.72 and 125.16 mg kg(-1) of P2O5 in a randomized block design with three replications. The highest levels of N and P showed higher accumulation of nutrients in both the shoot and root while for the micronutrients that effect was caused only by P. The species showed high nutritional requirement for N, P used more efficiently and supply of nutrients is greater for shoot seedling.
