"Determination of Nitrogen and Phosphorus requirements of Large Leaf Mahogany (Swietenia Macrophylla King.) Seedlings"
Nitrogen and phosphorus requirements of large leaf mahogany seedlings were determined using the sand culture technique. The study aimed to determine the treatments that will give the best height, diameter, shoot, and root developments of seedlings...
