In Today’s agriculture, seaweed serves as an organic rich product possessing rich source of growth promoting substances such as IAA, kinetin, zeatin, gibberellins, auxins, cytokinins, metabolic enhancers, macro and micro elements, amino acids and vitamins. The experiment was aimed to evaluate the effect of seaweed invigoration treatments on physiological performance of bhendi seeds in the Department of Seed Science and Technology Laboratory, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai. Seaweed nano powder of Sargassum myricocystum and Kappaphycus alverzii were ball milled for 2h and dry dressed on bhendi seeds @ 1, 2, 3 and 4 g/ Kg of seeds for 0.5h, 1h and1.5h of shaking durations were subjected for seedling evaluation test. The results revealed that, among all the dry dressing treatments, seeds treated with Sargassum myricocystum @ 1g/kg for 0.5h and Kappaphycus alverzii @ 2g/kg for 1h, registered higher seed quality parameters. Seed germination of bhendi significantly exhibited in Sargassum myricocystum 1g/kg for 0.5h and Kappaphycus alverzii 2g/kg for 1h. Radicle length, plumule growth, seedling vigour index I and II, dry matter production and other germination attributes increased by the application of seaweed nano powder. Seaweed nano powder was found to contain higher growth promoting substances, when analysed using GC-MS analysis.
