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.
