Enter the number of days from sowing to germination, the number of days from germination to maturity under optimal conditions, and the adjustment for growing conditions and desired stage at harvest into the calculator to determine the Days to Maturity.

Days To Maturity Formula

The following formula can be used to calculate the Days to Maturity (DTM).

DTM = S + G + M

Variables:

  • DTM is the Days to Maturity
  • S is the number of days from sowing to germination (days)
  • G is the number of days from germination to maturity under optimal conditions (days)
  • M is the adjustment for growing conditions and desired stage at harvest (days)

To calculate the Days to Maturity, add the number of days from sowing to germination, the number of days from germination to maturity under optimal conditions, and the adjustment for growing conditions and desired stage at harvest.

What is a Days To Maturity?

Days to Maturity (DTM) is a term used in gardening and farming, referring to the number of days a plant takes to grow from a seed to a mature state where it’s ready for harvest. This period varies for different plants and is influenced by factors such as the type of seed, the growing conditions, and the desired stage of the plant at harvest. DTM is a crucial factor for farmers and gardeners in planning their planting and harvesting schedules.

How to Calculate Days To Maturity?

The following steps outline how to calculate the Days To Maturity.


  1. First, determine the number of days from sowing to germination (S).
  2. Next, determine the number of days from germination to maturity under optimal conditions (G).
  3. Next, determine the adjustment for growing conditions and desired stage at harvest (M).
  4. Finally, calculate the Days To Maturity using the formula DTM = S + G + M.
  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.

number of days from sowing to germination (S) = 10

number of days from germination to maturity under optimal conditions (G) = 20

adjustment for growing conditions and desired stage at harvest (M) = 5
