THE EFFECTS OF DIFFERENT FERTILIZER APPLICATION ON SEED GERMINATION AND GROWTH OF KHAYA SENEGALENSES
Abstract
ABSTRACT
This study investigates the effects of various fertilizers on the seed germination and early growth of Khaya senegalensis (African mahogany), a valuable tropical tree species. Fertilizers applied include organic sources such as cow dung, goat droppings, sheep droppings, and chicken droppings, as wel as inorganic NPK fertilizer. The experimental design involved a randomized complete block setup,with controlled application rates and regular data collection on germination rates,shoot height, number of leaves, and stem weight. Results indicated that NPK fertilizer produced the highest growth metrics, including a maximum shoot height of 62 cm, followed by chicken droppings at 59 cm. Goat droppings were the least effective. The study concludes that while inorganic fertilizers like NPK yield rapid and significant growth, combining organic and inorganic fertilizers could enhance soil health and sustainable forestry practices. Recommendations include precise fertilizer application, regular soil testing, and further research under different environmental conditions.
