Other claims from this paper (18)
- Observation No single weed-control method was satisfactory.
- Observation Late-germinating Rottboellia tillered profusely despite early control.
- Observation Plots had heavy Rottboellia infestations and seed by harvest.
- Observation Untreated controls had 8·6 t Rottboellia dry matter ha −1.
- Intervention effect Untreated maize yielded half as much as handweeded plots.
- Intervention effect Karase harrowing effectively removed pre-emergence weed flushes.
- Intervention effect Paraquat effectively removed pre-emergence weed flushes.
- Observation Pre-emergence techniques delayed planting and could intensify downy mildew.
- Intervention effect Handweeding increased maize yield and decreased weed dry weight.
- Intervention effect Mungbean intercropping initially suppressed Rottboellia.
- Observation Mungbean harvest openings allowed explosive late-season weed growth.
- Intervention effect Banded pendimethalin plus atrazine followed by cultivation was as effective as handweeding.
- Intervention effect Broadcast pendimethalin plus atrazine was as effective as handweeding.
- Intervention effect Broadcast pendimethalin followed by 2, 4-D was as effective as handweeding.
- Observation Low-cost weed practices gave high net returns while costly herbicides gave low returns.
- Intervention effect Fertilizer without weed control increased maize yield 62%.
- Intervention effect Weed control without fertilizer increased yield 107%.
- Intervention effect Combining fertilizer and weed control increased yield 167%.
