Effect of Provenance and Seed Treatments on Occurrence of Seed Borne Diseases and Storability of Groundnut (Arachis hypogaea L.)

The laboratory experiment was conducted during 2017-18 to know the effect of provenance and seed treatments on occurrence of seed borne diseases and storability of groundnut (Arachis hypogaea L.). Groundnut varieties viz., TAG-24, G2-52, collected from different locations of Bagalkot, Dharwad and Belagavi districts, collected seed samples was stored in HDPE bags in Department of Seed Science and Technology, College of Agriculture, Vijayapur. The study exhibited that the untreated seeds lost its viability at a faster rate than the treated seeds. Among the seeds treatments, Captan 70 % + Hexaconazole 5 % (TAQAT 75 WP) @ 3g / kg treated seeds stored better up to ten months as compared to other treatments and control. The per cent infection due to interaction of provenance and seed treatments at the end of the storage was highest (13.06 %) observed in Yedahalli location with control and lowest (5.50 %) was seen in in Budihal location with Captan 70 % + Hexaconazole 5 % (TAQAT 75 WP) @ 3g / kg. The seed germination percentage due to interaction of infection level and seed treatments at the end of the storage was highest (80.00 %) in Budihal location with Captan 70 % + Hexaconazole 5 % (TAQAT 75 WP) @ 3g / kg and lowest (55.30 %) was recorded in Yedahalli location with control. This may be due to load of the pathogens during seed development and maturation consistent high humidity and temperature during storage period. The Other seed quality parameters were also recorded similar trend during the storage.
