Planting Geometry of winter Winter Wheat (Triticum aestivum) Can Reduce Jointed Goatgrass (Aegilops cylindrica) Spikelet Production

摘要

A 1984-1985 and 1988-1989 field study near Pullman, WA, evaluated the effect of two winter wheat planting geometries on the growth of wheat and competition against jointed goatgrass. Treatments included paired and constant row planting geometries of wheat and locations of jointed goatgrass within each geometry. No planting geometry by weed location interaction occurred at any Harvest date for plant height, shoot number, leaf area, plant dry weight, or N uptake for either wheat Or jointed goatgrass.
