    Effect of Plant Products and Containers on Storage Potential of Maize Hybrid Cv. Arjun
    (UAS, Dharwad, 2012) Asha A.M.; M.B. Kurdikeri
    An investigation was undertaken to ascertain the storage potential of maize seeds with ten seed treatments and three packing materials. Seeds with initial 8.0 per cent moisture content were treated with powders of neem leaf, castor leaf, pongamia leaf, tulsi leaf, mandarin peel, sweet flag, arappu leaf, parthenium leaf, wood ash, thiram and control and packed in three containers viz., cloth bag, polythene bag (700guage) and vacuum packaging and stored under ambient conditions. The maize cv. Arjun recorded higher germination, field emergence, vigour index, seedling dry weight, lower electrical conductivity, moisture content, seed infection and seed infestation at the end of 14 months of storage irrespective of containers and treatments. Among the seed treatments, seed treated with thiram recorded higher germination (90.33%), field emergence, vigour index (3384), seedling dry weight, lower electrical conductivity, moisture content seed infection (4.90%) and seed infestation (10.65%) compared to other seed treatments at the end of storage period. Seeds packed in vacuum packaging recorded higher germination (90.50%), speed of germination, lower electrical conductivity, moisture content, seed infection and seed infestation as compared to seeds stored in cloth bag and polythene bag at the end of 14 months of storage. In the interactions of seed treatments and containers (TxC) seed treated with thiram and stored in vacuum packaging and polythene bag maintained higher germination (90.33 and 82.82%, respectively), field emergence, vigour index, seedling dry weight, lower electrical conductivity, moisture content and seed infection at the end of 14 months of storage.
