Other claims from this paper (18)
- Observation Before land preparation, grasses comprised 20% of flora.
- Observation Before land preparation, spiderwort comprised 10% of flora.
- Observation At 10 weeks, broadleaf weeds comprised 64% of flora.
- Observation At 10 weeks, grasses comprised 14% of flora.
- Observation At 10 weeks, spiderwort comprised 8% of flora.
- Observation At 10 weeks, sedges comprised 14% of flora.
- Observation Oldenlandia, Cyperus and Desmodium species were prevalent weeds; Mimosa pudica was minor.
- Intervention effect Herbicides improved kenaf height, stem girth, and leaf number.
- Intervention effect Herbicides reduced weed flora composition and weight versus weedy control.
- Intervention effect Oxyfluorfen at tested rates reduced weed dry weight by 60–70%.
- Intervention effect Fluazilof-p-butyl at 225 and 300 g ai/ha reduced weed dry weight by 60–70%.
- Intervention effect Quazilofop-P-ethyl at 100 and 200 ml/ha reduced weed dry weight by 60–70%.
- Observation Weed-free plots had the highest weed control efficiency.
- Intervention effect Oxyfluorfen at 1.20 and 1.44 kg ai/ha achieved at least 80% weed control efficiency and fibre yield comparable with weed-free plots.
- Intervention effect Fluazilofop-p-butyl at 300 g ai/ha achieved at least 80% weed control efficiency and fibre yield comparable with weed-free plots.
- Intervention effect Quazilofop-p-ethyl at tested rates gave 50–65% weed control efficiency.
- Observation Weedy check plots had 65% lower kenaf fibre yield.
- Recommendation The authors recommend reviewing Quazilofop-p-ethyl doses for efficacy.
