Abstract:

Sweet corn (Zea mays L. spp. saccharata) also known as sugar corn is a hybridized variety of maize (Zea mays L.) specifically bred to increase the sugar content. The information on storage of sweet corn seeds to preserve viability and vigour from harvest to next planting season is of prime importance in any seed production programme. Certain seed treatments and storage containers are known to influence the storability of seeds in several crops. Hence, the laboratory experiment was conducted from 2017-2018 at Regional Agricultural Research Station, Hitnalli Farm, Vijayapur to ascertain the effect of polymer coat, seed treatment chemicals and containers on sweet corn seed quality during seed storage. The experiment was carried out in two factorial two factorial design. First factor consisted of eight treatments and second factor consisted of two containers viz., cloth bag and polythene bag. The results of investigation revealed that seeds stored in HDPE (polythene) bag showed better storability as compared to the cloth bag. At the end of nine months of storage period, seeds treated with polymer seed coating @ 10 ml/kg of seed + deltametrin 2.8EC @ 0.4ml/kg seed + bavistin 50% WP @ 2g/kg and seeds stored in polythene bag recorded significantly higher seed germination (89.00%), shoot length (17.81 cm), root length (19.58 cm ), seedling vigour index (3390), ten seedling dry weight (2.36 g), 100 seed weight (10.81g) and lower EC value (0.341dSm-1) as compared to control. The moisture content, seed infection and insect infestation were least in the seeds stored in polythene bags compared to the seeds stored in cloth bags.
