Other claims from this paper (12)
- Association Weed density and biomass responded strongly to weed control and fertilizer rates.
- Observation Unweeded plots with 140:36:43 kg NPK had higher weed density.
- Observation Echinichloa crusgalli was the dominant weed species.
- Intervention effect Three hand weedings controlled the most weeds.
- Intervention effect Herbicides controlled weeds with over 80 and 70% effectiveness.
- Association Rice grain yield correlated negatively with weed density.
- Intervention effect Herbicide with one hand weeding and 160:46:53 kg NPK yielded 81- 104% more grain than no weeding.
- Observation Yield was similar across fertilizer doses with herbicide and one hand weeding and BRRI weeder.
- Association Yield and yield components had a strong positive linear relationship.
- Intervention effect Herbicide with hand weeding and 120:26:33 kg NPK gave higher net return of 1145 $/ha.
- Observation Herbicide weed management with reduced fertilizer had a higher benefit cost ratio.
- Recommendation Herbicide with one hand weeding and reduced fertilizer is proposed for lower costs and satisfactory yield.
