Enter the kernels per spike and the spikes per 3 ft of row into the Calculator. The calculator will evaluate the Wheat Yield. 

Wheat Yield Formula

WY = (KPS * SP3) *.0319

Variables:

  • WY is the Wheat Yield (bu/acre`)
  • KPS is the kernels per spike
  • SP3 is the spikes per 3 ft of row

To calculate Wheat Yield, multiply the kernels per spike by the spike by 3-foot row, then multiply the result by .0319.

How to Calculate Wheat Yield?

The following steps outline how to calculate the Wheat Yield.

  1. First, determine the kernels per spike. 
  2. Next, determine the spikes per 3 ft of row. 
  3. Next, gather the formula from above = WY = (KPS * SP3) *.0319.
  4. Finally, calculate the Wheat Yield.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

kernels per spike = 34

spikes per 3 ft of row = 10
