Other claims from this paper (9)
- Intervention effect Raising N from 0 to 90 kg/ha increased weed density and dry matter.
- Intervention effect 60 and 90 kg N/ha were at par for tiller number, leaf area index and yield attributes of rice.
- Intervention effect All weed control methods reduced weed density and dry matter compared with the weedy check.
- Intervention effect All weed control methods increased rice growth and yield relative to the weedy check.
- Intervention effect Pre-emergence Orizo Plus® followed by SHW at 6 WAS and three hoe-weeding regimes lowered weed density and dry matter compared with a sole Orizo Plus® application.
- Intervention effect Pre-emergence Orizo Plus® followed by SHW at 6 WAS and three hoe-weeding regimes increased tiller number, panicle weight and grain yield compared with a sole Orizo Plus® application.
- Intervention effect With Orizo Plus® followed by one SHW or three hoe-weeding regimes, increasing N significantly increased rice grain yield.
- Intervention effect With Orizo Plus® applied alone, increasing N did not increase rice grain yield.
- Recommendation Orizo Plus® at 2.0 kg a.i./ha followed by one SHW at 6 WAS with N at 90 kg/ha is adequate to control weeds and increase rice yield in the transition zone of Nigeria.
