efficient forest restoration requires the planting of superior seedlings with optimum development potential. jack pine is an important species because it helps to maintain the structure and function of ecosystems and provides a habitat for a wide diversity of different types of animals. it has good growth and yield characteristics and is a profitable species for commercial forestry operations. curcuma longa (turmeric), a member of the zingiberaceae family, is a perennial plant that originates from southeast asia. it has gained widespread popularity and is used in traditional medicinal practices. the application of turmeric extract has been seen to have a positive impact on the development of wheat seedlings. this research aspires to find values of turmeric in the forestry field and hopes to satisfy the question of the impact of turmeric in the growth and survival of jack pine. jack pine seedlings were grown with 5% of turmeric by weight mixed in with soil, 10% turmeric by weight mixed in the soil, spraying turmeric with 10% concentration mixed in water, 30% turmeric concentration in water sprayed. i hypothesized that when turmeric is added to soil or sprayed with water dilution, it will promote height and diameter growth of jack pine. this hypothesis was rejected because increases in turmeric concentration resulted in lower height and root collar diameter of the seedlings. possibly, the component curcumin, which is an active ingredient in turmeric, can inhibit the growth of certain plants.
