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

Oat Yield Formula

OY = KPS * SPR * .0504


  • OY is the Oat Yield (bu/acre)
  • KPS is the kernels per spike
  • SPR is the spikes per 3 ft of row

To calculate Oat Yield, multiply the kernels per spike by the spikes per 3 foot row, then multiply by .0504.

How to Calculate Oat Yield?

The following steps outline how to calculate the Oat 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 = OY = KPS * SPR * .0504.
  4. Finally, calculate the Oat 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 = 50

spikes per 3 ft of row = 60
