Seed quality characters like thousand seed weight, seed moisture content, germination percentage, seedling root length, shoot length, seedling fresh weight and dry weight of Desmodium gangeticum collected from the research fields of AICRP on MAP and B, Thrissur during the year 2016 were evaluated after storing under different environments viz., 8%, 10% and 12% of moisture levels, cloth, polythene and aluminium as packing materials, ambient and refrigerated storage environments. Weather parameters in the storage environment were also recorded during the storage period. The suitable storage method for Desmodium gangeticum seeds was found by evaluating the seed quality characters. The result of the investigation showed that it is better to store the seeds at 8% moisture level, pack in polythene bags and kept in refrigerated environment for higher germination. The finding from this study could be used for better storage of Desmodium gangeticum seeds without losing its viability and thus the conservation of this valuable medicinal plant.
