Phosphorus (P) is a critical essential mineral nutrient for rice cultivation, particularly in the P-deficient, poorly drained soils of the slightly-saline coastal region of Bangladesh. This study was conducted during the monsoon season (August–December 2020) in Dumki upazila of Patuakhali district to determine the optimum P fertilizer requirement and evaluate P use efficiency (PUE) in T. Aman rice. There were eight P treatments (0, 3, 6, 9, 12, 15, 18, and 21 kg P ha⁻¹), each replicated three times. The results revealed significant improvements in plant height, effective tillers hill-1, grain yield, and total P uptake with rising P levels. The highest grain yield (4.99 t ha⁻¹) and straw yield (6.16 t ha⁻¹) were recorded at 15 kg P ha⁻¹, but the yields were statistically similar with the P rates as low as 9 kg ha-1, which also corresponded with peak agronomic efficiency (AE) and recovery efficiency (RE). Although higher P rates (18 and 21 kg ha⁻¹) marginally increased P uptake, they had no significant improvement of grain yield and led to lower use efficiency indices. Correlation analysis confirmed strong positive relationships between tillering, yield, and P uptake parameters. The findings indicate that 9-12 kg P ha⁻¹ is the optimum dose for maximizing yield and PUE in T. Aman rice under slightly-saline coastal conditions of south-central Bangladesh.
