TAILIEUCHUNG - Pre-sowing seed invigouration of direct seeded rice for early seedling vigour and improvement of yield in organic condition

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 bioagents viz local commercial bio-formulations Org-Trichojal, Org-Metajal, OrgBeauverijal, 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. | Pre-sowing seed invigouration of direct seeded rice for early seedling vigour and improvement of yield in organic condition
