Effect of different seed coatings and packaging on seed quality of maize (Zea mays L.) seeds during ambient storage condition

Abstract

Seeds of three different varieties of maize (HQPM-1, HQPM-7 and BIO-9681) were obtained from IARI, New Delhi. After thorough cleaning and grading the maize seeds were well dried before storage and treated with synthetic polymer @ 9 ml per kg of seed, biocide (Neem oil @ 10ml / kg) and fungicide (Carbendazim) 12% @ 2.5 g/kg. Seeds were stored for 3, 6, 9, 12, 15 and 18 months respectively under ambient condition. The results revealed that, the seed treatment with polymer @ 9 ml + Neem oil @ 10 ml/ kg of seed observed significant maximum germination percentage, shoot length, root length, seedling length and higher vigor index. Seeds stored in cloth bag recorded significantly maximum seed quality parameters compared to plastic bag.
