Phosphorus (P) deficiency is one of the most yield-limiting factors in lowland acid soils of Brazil. A field experiment was conducted during two consecutive years to determine dry-matter and grain yield, nutrient uptake, and P-use efficiency of lowland rice (Oryza sativa L.) grown on an acidic Inceptisol. Phosphorus rates used in the experiment were 0, 131, 262, 393, 524, and 655 kg P ha 21 applied as broadcast through termophosphate yoorin. Dry- matter yield of shoot and grain yield were significantly ( P < 0.01) and quadratically increased with P fertilization. Concentrations ( content per unit dry- weight leaves) of nitrogen ( N), P, and magnesium ( Mg) were significantly increased in a quadratic fashion with the increasing P rates. However, concentrations of potassium ( K), calcium ( Ca), zinc ( Zn), copper ( Cu), and iron ( Fe) were not influenced significantly with P fertilization, and Mn concentration was significantly decreased with increasing P rates. Phosphorus use efficiencies ( agronomic, physiological, agrophysiological, recovery, and utilization) were decreased with increasing P rates. However, magnitude of decrease varied from efficiency to ? efficiency. |
