dc.description.abstractThe present study was carried out in the field and laboratories of Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar, Haryana during 2018-2020 to study the effect of picking stages, seed treatments and containers on seed viability of okra (Abelmoschus esculentus L. Moench). The best picking stage of okra for quality seed production was found on the fruits developed on middle nodes (6th to 10th) as compare to lower (1st to 5th) and upper nodes (11th to 15th). The seeds obtained from middle nodes were used for further studies. To study the effect of seed treatment with different fungicides and botanicals, seven fungicides (carbendazim, tebuconazole, difeconazole, flusilazole, chlorothalonil, azoxystrobin and vitavax power) and three botanicals (Pongamia, neem and turmeric) were used. The treated seeds were kept in three different containers viz., Polythene bag, hermetic bag and metal box up to 18 months at ambient room conditions. Among the interaction effects of fungicide with containers, the seed treatment with azoxystrobin stored in metal box was found superior. While the interaction effect of botanicals with containers, the seed treatment with neem leaf powder stored in metal box was found best. During the entire period of this study, it was revealed that the germination was maintained above Indian Minimum Seed Certification Standards (>65%). All the seed quality parameters (germination, shoot and root length, seedling dry weight, vigour indices-I & II, catalase, superoxidase dismustase, dehydrogenase and peroxidase) were declined with the advancement of storage time except electrical conductivity. The present study also indicated that the fungicide treated seeds showed better performance than botanical treated seedsen_US
