Harrington thumb rule on seed storage
Harrington thumb rule on seed storage
|
- The following thumb rules by Harrington are useful measures for assessing the effect of moisture and temperature on seed storage.
- These rules are as follows:
- For every decrease of 1% seed moisture content, the life of the seed doubles. This rule is applicable when moisture content between 5 and 14%.
- For every decrease of 5°C (10°F) in storage temperature the life of the seed doubles. This rule applies between 0°C to 50°C.
- Good seed storage is achieved when the % of relative humidity in storage environment and the storage temperature in degrees Fahrenheit add up to hundred but the contribution from temperature should not exceed 50°F.
