Abstract
A nursery based experiment was conducted to study the effect of varied pre-sowing treatments on seed germinations of Tectona grandis (Teak). Seeds of selected species were subjected to six different pre-sowing treatments. Results revealed that, the highest germination percentage was observed 86.67% in Pith method, followed by 73.33% in soaking in normal water (72 hours) and 45% in soaking in normal water (24 hours). The highest germination value was found in T4 (21.82) followed by T3 (13.52), 8.37 in T5 (immersion in 80% concentrated H2SO4 for 20 minutes). Our result finds that pre-sowing treatment is obviously better than control. Pit method and soaking in normal water for 72 hours are highly recommended for maximum germination within the shortest period of time. These findings of the research will be helpful to take effective decision regarding the raising of large scale production of Tectona grandis (Teak) seedling in a cost effective way with ensuring their earlier germination.
