Abstract:

An investigation was carried out using ‘Luit’ variety of paddy (Oryza sativa L. indica) seeds to see the effects pre sowing seed treatment using different bio-agents viz local commercial bio-formulations Org-Trichojal, Org-Metajal, Org-Beauverijal, three different commercial cold adaptive microbial consortiums and also priming with Zinc oxide nano-particle in order to improve field performance. In the present investigation, Beauverijal was found to be the best bio-agent for seed treatment as the results indicate better early seedling growth followed by higher number of seeds/panicle, seed yield and less disease infestation. Bio-agents viz. Trichojal and Metajal were also found to be effective in lowering the disease incidence and increase in seedling vigour followed by better yield performance. Comparative performance of Microbial consortium (C4), Microbial consortium (C7), although designated as cold adaptive strains, does not impart any significant influence in enhancing seed vigour and early seedling growth. Performance of nano-priming is found to better than hydration and cold tolerant microbial consortium for most of the characters. The better adaptability of local commercial bio-agents in Trichojal, Metajal, and Beauverijal may lead to better performance in seed vigour, early seedling growth and final seed production.
