Corn acreage has been on the rise in southeastern Kansas in recent years because of the introduction of short-season cultivars which enable producers to partially avoid mid-summer droughts that are often severe on the upland, claypan soils typical of the area. In addition, producing a crop after wheat and in rotation with corn potentially provides producers an increase in revenue by growing three crops in two years. Recent interest and developments in oil-type sunflower provide an alternative to soybeans for growers to double-crop after wheat.
