2809. Hume, L.. 1982. The long-term effects of fertilizer application and three rotations on weed communities in wheat.. Can. J. Plant Sci., 62:741-750.
The effect of fertilizer application and three rotations (continuous cropping, fallow-wheat, and fallow-wheat-wheat rotations)on the species composition of the weed community was examined using rotations that had been running for 21-22 yrs. Fertilizer application tended to reduce community differences between continuous cropping and short-term wheat-fallow rotations. With the use of 2- or 3-yr wheat-fallow rotations and herbicide application, weed problems can be minimized in southeastern Saskatchewan.
