Straw Yield Estimate Calculator
Enter grain yield in tonnes per hectare and a non-negative straw-to-grain ratio.
A QUICK WALKTHROUGH
How to use this tool
- Enter non-negative grain yield in tonnes/ha.
- Enter a non-negative straw-to-grain ratio.
- Review the estimated straw yield.
Formula and scope
Estimated straw yield (tonnes/ha) = entered grain yield (tonnes/ha) × user-entered straw-to-grain ratio.
Limitations
The ratio is an assumption supplied by you. This tool does not infer crop species, actual grain yield, moisture basis, or harvest losses.

GOOD TO KNOW
Common questions
What ratio should I use?
Use a measured or independently sourced value suitable for the crop and conditions; none is recommended here.
Does this predict grain yield?
No. Grain yield and ratio are both user inputs.
