A factor in the grading of grains and oilseeds; i.e., dockage in wheat is described as "weed seeds, weed stems, chaff, straw, or grain other than wheat, which can be readily removed from the wheat by the use of appropriate sieves and cleaning devices; also, underdeveloped, shriveled and small pieces of wheat kernels removed in properly separating, properly rescreening, or recleaning." The term is also used to describe the amount of reduction in price taken because of a deficiency in quality.
