Test Weight

Test weight is a standard used in the marketing of wheat. It is the weight of grain contained in a one quart sample. A test weight equivalent to less than 58 lbs. per bushel may be subject to dockage; i.e., a reduction in the price the grower receives for his wheat. Unfortunately, research has shown that test weight and yield are not always positively correlated; i.e., high yield does not necessarily mean high test weight.

The test weight of wheat is determined by both environmental and genetic factors. Some varieties have characteristically higher test weight than others. Thus, when environmental conditions cause poor test weights, selection of a variety with high test weight potential often gives a higher test weight than other varieties.
