Shushant Kumar Kaushik, Anuj Kumar Rai, Vishal Singh

Seeds of maize (variety MH-7) were obtained from the Department of Genetics and Plant Breeding, SHIATS, India. After through cleaning and grading the maize seeds were well dried before storage and treated with polymer @ 3, 6 and 9 ml per kg of seed, fungicides and their combinations (i.e. polymer 3ml + thiram 2 g and polymer 6 ml + thiram 2 g etc.). Seeds were stored for 2, 4 and 6 months respectively under ambient condition. The results revealed that, the seed treatment with polymer @ 9 ml + thiram 2 g per kg of seed observed significant shoot length, root length, seedling length, viability, fresh weight and higher vigor index and high germination rate was observed for seed coated with polymer @6 ml+ thiram 2 g per kg of seed after 6 month of storage. Seeds stored in plastic box recorded significantly maximum seed quality parameters compared to cotton bag.
