Nitrogen and phosphorus fertilization in upland rice in the municipality of Humaitá at Amazonas State
ABSTRACT The fertilization management can contribute to a better agronomic performance of rice (Oryza sativa L.) plants in upland conditions. Thus, the objective in this study was to evaluate the development of rice plants fertilized with different doses of nitrogen and phosphorus in upland soil. Th...

| description | ABSTRACT The fertilization management can contribute to a better agronomic performance of rice (Oryza sativa L.) plants in upland conditions. Thus, the objective in this study was to evaluate the development of rice plants fertilized with different doses of nitrogen and phosphorus in upland soil. The experiment was conducted in a greenhouse using pots containing soil collected in the soil top layer of a plinthic alitic Haplic Cambisol. The design was completely randomized with a 4 x 4 factorial scheme, corresponding to 0 (zero), 150, 300 and 450 kg ha-1 of phosphorus and 0 (zero), 100, 200 and 300 kg ha-1 of nitrogen. Plant height, shoot dry matter, grain weight and number of tillers were evaluated. Fertilization with nitrogen and phosphorus positively affects the growth and development of rice plants in Humaitá, Amazonas state, grown in upland soil up to doses between 200 and 300 kg ha-1 of N and around 300 kg ha-1 of P2O5, in a plinthic alitic Haplic Cambisol. |
