Abstract: The study was conducted over a period of 5 months from March to July, 2017, to study the effect of varied pre-sowing treatments on seed germination of Tectona grandis (Teak) in the nursery area of College of Forestry, SHUATS, Allahabad. Seeds were subjected to 14 treatments including control i.e. T0 (Control), Tâ‚ (Soaked in normal water for 3 days), Tâ‚‚ (Sunlight for 3 days), T₃ (Alternate wet 12hrs and drying 12hrs for 10 days), Tâ‚„ (Soaked in cow urine for 6 days), Tâ‚… (Soaked in Cow dung slurry for 7 days), T₆ (Hammer treatment), T₇ (Sand paper), T₈ (Boiling 2 min), T₉ (Boiling 5 min), Tâ‚â‚€ (Conc. Hâ‚‚SOâ‚„ 15 min), Tâ‚â‚ (Conc. Hâ‚‚SOâ‚„ 20 min), Tâ‚â‚‚ (HNO₃ 15 min), and Tâ‚₃ (HNO₃ 20 min). Findings of the data revealed that pre-treatment of seed before sowing enhanced seed germination and seedling growth. The highest germination percentage (43.3%) was observed in T₃ (Alternate wet and drying) followed by Tâ‚… (Cow dung slurry 40%) and Tâ‚â‚ (Hâ‚‚SOâ‚„ 20 min 33.3%). The lowest germination (13.3%) was recorded in Tâ‚‚, Tâ‚„ and Tâ‚â‚‚ (sunlight, cow urine and HNO₃ 15 min) respectively. Seedling height, root length, collar diameter and number of leaves have resulted different performance trend and found as T₃, Tâ‚…, T₆, Tâ‚â‚€ and Tâ‚â‚ respectively and as for fresh and dry shoot weight, fresh and dry root weight trend of higher value was observed in T₃ and Tâ‚… respectively and the lowest in Tâ‚€. Observation for seedling quality parameter, it show difference in higher trend of value i.e. T₈ and T₉ for root shoot ratio-I, T₈ and Tâ‚â‚‚ for root shoot ratio-II while for Sturdiness quotient, highest value was observed in Tâ‚„ (cow urine).Therefore, the effect of pre-sowing treatment T₃ (alternate wet and drying) and Tâ‚… (cow dung slurry) was more effective in germination and production of quality seedling of Tectona grandis (Teak) in the nursery.
