abstract
A study was undertaken in the nursery area of College of Horticulture and Forestry, Jhalawar to assess the influence of different pre-sowing treatments on the germination of Tectona grandis (Teak) seeds. Seeds were subjected to 4 treatments including control (P ₀), Alternate wetting and drying (12 hours) for 21 days (P ₁), Soaking in cow dung slurry for 7 days (P₂) and Soaking in concentrated H₂SO₄ (75%) for 20 minutes (P₃). The results of the study indicated that pre-sowing treatments had significant influence on the germination parameters. The highest germination percentage, germination speed, faster germination and lowest mean germination were observed in seeds treated under alternate wetting and drying (12 hours) for 21 days (P ₁) followed by seeds soaked in cow dung slurry for 7 days (P₂). Among the pre-sowing treatments seeds treated under alternate wetting and drying (12 hours) for 21 days can be recommended for Tectona grandis on a broad scale. These research findings will provide valuable insights for making informed decisions on the cost-effective cultivation of Tectona grandis (Teak) seedlings on a large scale, ensuring their rapid germination.
