Yield is calculated by multiplying 2450 by the multipliers from the charts below.
For example: A plot with a stand of 19,000, a head size of 7.5 inches, a seed size
of light medium, good seed count of 85% and no seed in the center 2".
Yield calculations for this plot would be: 2450 x .95 x .91 x .9 x .85
x .95 = 1539.3 lbs/acre
