The Effect of Nutri-Priming in Revolutionising Germination and Seedling Vigour in Green gram: Unleashing Seed Power

Abstract

Seed priming had a distinct, concentration-dependent effect on the germination and early growth of green gram (Vigna radiata L., cv. Samrat). Nutri-priming solutions were prepared using digested banana stems at concentrations of 0.00 mL (T₁), 0.25 mL (T₂), 0.50 mL (T₃), 1.00 mL (T₄), 2.00 mL (T₅), 3.00 mL (T₆), and 4.00 mL (T₇), diluted in 15 mL of distilled water. The control (T₁) had only 15 mL of distilled water. Moderate priming doses significantly improved several germination traits, including germination potential, germination energy, germination index, and average germination time. Among all treatments, T₄ (1.00 mL) consistently delivered the best results, exhibiting the highest germination potential (87.22%), maximum germination energy (86.32%), the quickest germination rate (T₅₀ = 1.512 days), and the shortest mean germination time. Treatments T₃ (0.50 mL) and T₅ (2.00 mL) also enhanced germination compared to the control, whereas higher concentrations (T₆ and T₇) suppressed germination, indicating that excessive priming disrupts normal metabolic processes. Measurements of seedling growth emphasised the benefits of optimal priming levels. T₄ (1.00 mL) produced the tallest seedlings (31.20 cm) and the greatest fresh biomass, while T₃ (0.50 mL) generated the highest dry matter and achieved the greatest Vigour Index II, demonstrating improved seedling strength.
