It is a volumetric measurement based on grain weight in one official bushel or 1.244 cubic feet. Test weight is an important predictor of milling yield for … "It has been documented that wheat with a test weight below 54 to 56 pounds per acre may have lower yield potential, and less seedling vigor, than higher-test-weight seed. Standard or higher The crops they grow cover over 6 million acres of farm land across the province, generate over $4.1 billion in production value, result in over $18 billion in economic output and are responsible for over 75,000 jobs in the province. So, harvesting wheat too wet, above 15 percent moisture, is not a good idea because often test weight will be lighter. inches). An official test weight measurement uses standardized equipment to determine the mass (weight) of a sample quart of grain, and then converts this to a pounds per volumetric bushel basis. High-test weight wheat usually has relatively more extractable flour and less bran and is therefore more valuable to the end-user. 1). to livestock on-farm. When the starch fill is incomplete due to adverse weather conditions, the protein concentration is elevated from 1 to 3 percent.
