Other claims from this paper (7)
- Intervention effect Before spring seeding, stinkweed and lamb’s-quarters were more abundant on wheat after fallow than on continuous cropping.
- Intervention effect After seeding, continuous cropping produced the largest weed densities of green foxtail, thyme-leaved spurge and vetch.
- Intervention effect In most instances, Canada thistle was most abundant on continuously cropped and nonfertilized plots.
- Intervention effect After spring seeding, green foxtail was the only species with a larger density on fertilized plots.
- Observation Fertilizer application and rotation interacted to influence species composition of the weed community.
- Intervention effect Fertilizer application tended to reduce community differences between continuous cropping and short-term wheat-fallow rotations.
- Recommendation Weed problems can be minimized in southeastern Saskatchewan with 2- or 3-yr wheat-fallow rotations and herbicide application.
