Abstract:

Securing uniform crop establishment in sesame (Sesamum indicum L.) is a persistent agronomic challenge owing to its inherently small seed size, erratic germination behavior, and vulnerability during the early seedling phase. The present investigation was designed to systematically assess the influence of seven organic seed treatments on germination percentage, root and shoot elongation, and the integrated Seedling Vigor Index (SVI) of sesame variety VRI 3 under Rabi 2026 pot culture conditions at PGP College of Agricultural Sciences, Namakkal, Tamil Nadu. A Completely Randomized Design (CRD) with three replications was adopted, encompassing: untreated control (T1), Azospirillum @ 10 mL/kg (T2), Zinc Solubilizing Bacteria @ 100 mL/kg (T3), Trichoderma viride @ 4 g/kg (T4), Pungam leaf extract @ 1% (T5), Seaweed extract @ 5% (T6), and Panchagavya @ 6% (T7). Treatment T6 recorded the highest germination percentage (49.3%) and the greatest SVI value (626.60), attributed to the phytohormonal constituents and bioactive polysaccharides present in Sargassum spp. extract. Post-emergence structural assessment at 15 and 20 Days After Sowing (DAS) revealed that T2 (Azospirillum) produced the most vigorous root (6.90 cm) and shoot (13.70 cm) development by 20 DAS, driven by rhizosphere auxin biosynthesis and biological nitrogen fixation. Trichoderma viride (T4) delivered a balanced performance, recording 33.3% germination and an SVI of 513.15. In contrast, Pungam leaf extract (T5) exhibited pronounced allelopathic phytotoxicity, suppressing germination to 4.0% and causing complete seedling mortality by 20 DAS. These findings endorse the application of seaweed extract for rapid field establishment and Azospirillum or Trichoderma viride for sustained early seedling growth as part of an ecologically sound sesame production system.
