How is corn test weight calculated?

Hellevang (1995) offered a simple formula for estimating the increase in test weight with grain drying. In its simplest form, the equation is (A/B) x C; where A = 100 – dry moisture content, B = 100 – wet moisture content, and C = test weight at wet moisture content.

How is test weight calculated?

Test weight is determined on each load of grain sold by weighing a known volume of the grain. If the weight is lower than the acceptable range, the sale is “docked” on a percentage basis. The seller of grain with test weight greater than the acceptable range is usually not rewarded for a superior product.

What causes low test weight in corn?

Heat and drought stress tend to decrease test weight because they affect the photosynthetic process and reduce kernel weight. Below-normal temperatures during final kernel filling impact the photosynthetic process, resulting in less than optimum starch deposition in the kernels.
