Description Orthodox seeds can be dried to low moisture contents with considerable advantage to longevity. Seed drying involves the evaporation of moisture from seed surface into the outer atmosphere ana is influenced primarily, by the gradient in relative humidity between the seed and drying environment. The various methods of drying seeds to reduce moisture content for subsequent storage were discussed. Sun-drying, although is the cheapest method usually practiced, affects seed quality and is impractical in humid tropics due to the prevailing high relative humidity. While using commercial seed dryers for artificial during, proper control of the air temperature is essential to minimize seed deterioration. A low temperature-relative humidity drying is recommended to reduce the moisture content to 5±2 per cent for long-term conservation of the germplasm seeds. The relative advantages and the associated problems in drying seeds to such low moisture content are discussed.
