This page computes weight of the substance per given volume, and answers the question: How much the substance weighs per volume. for Weight and Measurements: Crops, Bushels, Test Test weight of wheat is considered the most common and easiest way to quantify wheat. RealAgriculture Agronomy Team. Test weight increases as grain dries partly because kernel volume tends to shrink with drying, so more kernels pack into a volume bushel, and partly because drier grain is slicker, which tends to encourage kernels to pack more tightly in a volume bushel. Much effort has been devoted to developing methods which would more accurately predict flour yield. Jim Isleib, Michigan State University Extension -

What we did. August 6, 2012. Test weight (kg/hl) is the metric system equivalent to pounds per bushel. because both are associated with semolina yield. However, once Low-test-weight seed usually germinates well, but seedlings tend to have lower vigor than seedlings from seed with higher test weights. High-test weight wheat usually has relatively more extractable flour and less bran and is therefore more valuable to the end-user. Student Focused. Test weight is used as an overall indicator of grain quality and provides a rough estimate of potential flour yield. Test weight is important with corn because if it drops too low sellers are docked and buyers can even reject the grain. Keep an eye out for Temperatures that exceed 85 degrees during the day and 60 degrees at night during grain filling hasten kernel development at a faster pace than the rate at which the kernel fills. 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. The difference between the two bushels could mean a loss for you. In this very informative audio version of the Wheat School, Johnson explains exactly what physical process occurs when wheat is wetted and re-wetted (sometimes even just from a heavy dew!

In the case of wheat, feeding grain with a test weight of more than 50 pounds per bushel results in very few differences in animal weight gain compared to feeding higher test weight wheat. Low test weight grains have less starch with more concentrated protein and seed coat or fiber. to the industry standard. Test weight. Husn.] Related Articles.
