The present investigation, entitled "Enhancing Germination Rates Through Effective Seed Treatment Methods in Sulphi palm (Caryota urens)" was conducted at Tissue Culture Lab premises, Department of Floriculture and Landscape Architecture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during December 2024-April 2025. The experiment was laid out in Completely Randomized Design with three replications and used fourteen different treatments viz., T₁ (Soaking in 100 °C water for 1 minute), T₂ (Soaking in Cow urine for 24 hours), T₃ (Rubbed with sandpaper), T₄ [Soaking in HCL (50%) for 5 minutes], T₅ [Soaking in HCL (50%) for 10 minutes], T₆ [Soaking in H₂SO₄ (50%) for 25 minutes], T₇ [Soaking in H₂SO₄ (50%) for 10 minutes], T₈ (Soaking in fresh cow dung slurry for 24 hours), T₉ [Soaking in HCL (50%) + H₂SO₄ (50%) for 5 minutes], T₁₀ (Oven heating at 60^o C for 10 second), T₁₁ [Soaking in Alcohol (50%) solution for 15 minutes], T₁₂ (Soaking in GA₃ @ 1000 ppm for 48 hours), T₁₃ (Soaking in GA₃ @ 1500 ppm for 48 hours) and T₁₄ (Control-soaking in water for 24 hours). The results revealed that significant variations among treatments with respect to germination parameters. Seeds treated with GA₃ @ 1500 ppm (T₁₃) showed superior performance across most parameters, recording the shortest germination time (41 days), highest seedling height (20.06 cm), maximum stem girth (2.30 mm), highest survival percentage (88.64 percent). The highest germination percentage (86 percent) was observed in T9 [Soaking in HCL (50%) + H₂SO₄ (50%) for 5 minutes], while the minimum values for both germination and root growth were recorded in T₁ (Soaking in 100 °C water for 1 minutes).
