Weed Control in Dryland Cropping Systems

---

Summary.
Moisture is the most limiting factor to dryland crop production in western Kansas. As cropping intensity is increased from a wheat-fallow rotation to a wheat-summer cropfallow rotation, moisture efficiency becomes the
most critical factor that leads to a successful cropping system. For these reasons, there is very little tolerance for weed development and growth in the more intensive cropping systems in western Kansas. In the wheat-fallow system, the 24-month cycle consists of 9 months of crop and 15 months of fallow. Producers who do not control weeds during the first summer after wheat harvest can often harvest at close to a normal wheat yield, which is 30 to 40 bushels. This indicates the wheat-fallow system is not intensive enough to efficiently utilize the moisture received. Common weed species in the wheat-fallow system are winter-annual broadleaf weeds such as tansy mustard, flixweed, shepherdspurse, field pennycress, and purple mustard; spring-annual broadleaf weeds such as kochia, Russian thistle, common sunflower, pigweed species, and common lambsquarters; and winter-annual grasses such as jointed goatgrass, downy brome, Japanese brome, cheat, and weedy rye.
