Other claims from this paper (13)
- Intervention effect Nontreated plots had greater weed biomass than herbicide-treated plots.
- Intervention effect Herbicide reduced weed biomass by 89% to 99%.
- Intervention effect Fertilizer placement did not influence weed biomass in herbicide-treated plots.
- Intervention effect Fertilizer placement greatly influenced weed biomass in nontreated plots.
- Intervention effect Surface fertilizer increased weed biomass versus below-surface placement.
- Intervention effect Fertilizer placement did not affect weed density at 60 days.
- Observation Nontreated plots yielded 700 to 2080 kg per hectare.
- Intervention effect Grain yield was similar between herbicide-treated and weed-free plots.
- Intervention effect Banded basal fertilizer within rows did not influence grain yield.
- Intervention effect Banded basal fertilizer between rows did not influence grain yield.
- Intervention effect Broadcast basal fertilizer decreased grain yield to 2200 kg per hectare.
- Intervention effect Rice yield was usually lower with surface broadcast than subsurface fertilizer.
- Recommendation The authors conclude that surface broadcast basal fertilizer may produce high weed pressure.
