Formula's For Estimating Wheat Yields
1) Bushels = (Heads per foot) X (spikelets per
head) X (2.3)
(divided by row space in
inches) X 0.48 per acre
2) Bushels Per Acre of Hard Red Spring Wheat = kernels per head X heads in 3 ft X 0.0319
3) Bushels Per Acre of Durum = kernels per head X heads in 3 ft X 0.0377
4) Bushels Per Acre of Barley = kernels per head X heads in 3 ft X 0.0389
5) Bushels Per Acre of Wheat =
(# heads/3 feet row) X (spikelets/head) X (kernels/spikelet) X 0.142
(divided by row spacing (inches)
Formulas 2, 3, and 4 are for 7 inch row spacing and three foot of row
(For 6"
spacing, multiply final answers above by factor of 1.17)
Examples 2, 3, 4 and 5 are based on three foot row sample.
