Influence of Polymer Coating, Biocides and Packaging Materials on Storability of Maize (Zea mays L.) Seeds

摘要

An experiment was conducted to study (he influence of polymer coating, biocides and packaging materials on storability of maize seeds, during 2012-13. Maize seeds were treated with biocide (castor oil @ 10 ml/kg of seed) and stored in vacuum plastic bags for 6 months which showed significant higher percentage of seed viability, germination {%), seed vigor, root length, shoot length and seedling length as compared to other treated seeds were stored in vacuum plastic bag and other packaging materials.T|ie present investigation coopludes that the treatment with castor oil "wss'superior as it retained seed germination {%), shoot length, root length, seedling length, vigor index, seed viability and seed vigor. It is also found that vacuum plastic bags are the best options among normal plastic bags, cloth bags and jute bags for seed packing in terms of maintaining the seed quality as reflected in the varied parameters ol the seed quality assessment indicators.
