Abstract: A field experiment was conducted to assess the effect of varying levels of nitrogen (N), phosphorus (P), and potassium (K) on rice performance (Oryza sativa L.) during the spring crop of 2019 at the Rice Research Station, Burma. Eighteen treatment combinations were tested using a factorial RCBD design. Results showed that incremental N supply positively influenced plant height, tiller density, and grain yield. The highest grain yield (9330 kg ha??) and net economic returns were achieved with the NPK combination of 100 - 40 - 20 kg ha??. This study recommends this fertilizer regime for FG12 - 259 on Lichfield Clay to optimize yield and economic benefits.
