Module 6: Seed storage

Seeds are the vehicle for delivering the improvements in a crop to the farmer’s field. They are therefore a critical input in agricultural production. Seeds are also unique in that they must remain alive and healthy when they are used and that they are also the input that farmers can produce by themselves.

It is estimated that 25–33% of the world grain crop, including seeds, is lost each year during storage. To avert this obvious drawback to food security and nutrition, this module provides the underlying principles for effective seed storage and the associated practices. The module provides guidance on the preservation of seeds under controlled environmental conditions so as to maximize seed viability for the long periods that may be required from harvesting through processing to planting.
