| Inter-row hoeing is known to control tap-rooted and erect weed species more effectively in winter wheat than weed harrowing. However, little is known about its effectiveness for use in the spring in winter wheat grown at wide row spacing (240 mm) under the influence of different placement of fertiliser. Two field experiments, one in 1999 and one in 2000, were conducted to study the influence of fertiliser placement, timing of inter-row hoeing, and driving speed on the weeding effect on different weed species and crop growth. Placement of fertiliser below the soil surface improved crop growth and grain yield in both years compared with placement on the surface, but weeds surviving hoeing were not more suppressed by the improved crop growth. Timing was not... |
