- Intervention effect Fertilizer formulations differed significantly in rice yield attributes.
- Intervention effect USG at 104 kg ha-1 gave maximum grain yield of 6.391 t ha-1, 54% above control.
- Intervention effect The 104 kg ha-1 USG yield was statistically similar to USG at 78 kg ha-1.
- Intervention effect The 104 kg ha-1 USG yield was statistically similar to NPK briquettes at 104 kg ha-1.
- Intervention effect Deep placement of USG improved applied N recovery versus broadcast prilled urea.
- Intervention effect Deep placement of NPK briquettes improved applied N recovery versus broadcast prilled urea.
- Intervention effect Deep placement of NPK briquettes improved N use efficiency versus broadcast prilled urea.
- Intervention effect USG at 78 kg ha-1 maximized apparent N recovery, N use efficiency, gross margin and marginal benefit-cost ratio.
- Recommendation The authors recommend 78 kg ha-1 USG for profitable cultivation of BRRI dhan46.
