Other claims from this paper (7)
- Association Weed parameters depended strongly on year weather, herbicide application and their interaction.
- Intervention effect Total weed dry weight averaged 760.7 g m-2 in control and 142.2 g m-2 in herbicide-treated plots.
- Observation Johnsongrass accounted for 34.8% of weed dry weight in controls and 48.7% in treated plots.
- Observation Johnsongrass biomass increased over the years despite herbicide treatment.
- Association Maize grain yield was negatively related to Johnsongrass dry weight in untreated controls.
- Association Under herbicide treatment maize grain yield was higher at lower Johnsongrass dry weight.
- Recommendation Authors recommend crop rotation in place of continuous maize to prevent Johnsongrass prevalence and raise productivity.
