Mushroom Yield Formula

The following two example problems outline the steps and information needed to calculate the Mushroom Yield.

MY = WM / WDS ร— 100

Variables:

  • MY is the Mushroom Yield (%)
  • WM is the total weight of the mushrooms 
  • WDS is the total weight of initial dry substrate 

To calculate mushroom yield, divide the total weight of the mushrooms by the initial dry substrate weight, then multiply by 100 to express biological efficiency as a percentage.

How to Calculate Mushroom Yield?

The following steps outline how to calculate the Mushroom Yield.


  1. First, determine the total weight of the mushrooms. 
  2. Next, determine the total weight of initial dry substrate. 
  3. Next, gather the formula from above = MY = WM / WDS * 100.
  4. Finally, calculate the Mushroom 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.

total weight of the mushrooms = 300

total weight of initial dry substrate = 600

MY = WM / WDS * 100 = ?
