Effect of Sludge and NPK Fertilizer on the Growth of Oil Palm (Elaeis guineensis Jacq.) Seeds in Main Nurseries

The research aimed to determine the effect of sludge and NPK fertilizer their combination gain best result in growth palm oil seedlings main nursery. This used a factorial, completely randomized design. first factor was sludge, which has three dosages: 10 g, 20 30 g per plant. second fertilizer, 5 15 Twenty-seven units trials were obtained from 9 treatment combinations repetitions. Each trial unit consisted 4 plants, with 108 experimental plants. parameters plant height, number leaves, stem diameter, root volume, dry weight, crown ratio. practical analyzed using Duncan's Multiple Range Test at 5%. findings indicated that adding 15:15:15 increased growth, namely ratio leading increasing seedlings.
