e0“N-dose 151.8 kg ha-1 under postemergence herbicide contributed to the second highest grain yield (6.41 t ha-1) with the highest benefit cost ratio of 1.60 but 50.6 kg N ha-1 under post-emergence herbicide showed the maximum Nitrogen use efficiency of 0.49.”

Other claims from this paper (11)
- Observation Scirpus maritimus L. had the greatest visual abundance among weeds in the rice plots, at 58%.
- Intervention effect Post-emergence herbicide gave higher weed control efficiency than pre-emergence herbicide.
- Intervention effect Post-emergence herbicide without nitrogen gave the highest weed control efficiency, 97.39, at 60 days after transplanting.
- Intervention effect Nitrogen at 200.4 kg ha-1 with post-emergence herbicide gave the highest number of tiller per hill, 13.00.
- Intervention effect Nitrogen at 200.4 kg ha-1 with post-emergence herbicide gave the highest total dry matter, 1568.6 g m-2.
- Intervention effect Nitrogen at 200.4 kg ha-1 with post-emergence herbicide gave the highest panicles per hill, 10.60.
- Intervention effect Nitrogen at 200.4 kg ha-1 with post-emergence herbicide gave the highest filled grains per panicle, 125.20.
- Intervention effect Nitrogen at 200.4 kg ha-1 with post-emergence herbicide gave the highest grain yield, 6.46 t/ha.
- Intervention effect N-dose 151.8 kg ha-1 under postemergence herbicide gave second highest grain yield of 6.41 t ha-1.
- Intervention effect N-dose 151.8 kg ha-1 under postemergence herbicide gave highest benefit cost ratio of 1.60.
- Recommendation The authors suggest nitrogen up to 151.8 kg ha-1 with suitable post-emergence herbicide for profitable rice production.
