Abstract
Results of an experiment to determine the effect of different rates methods of application of three N sources on the yield of oil palm on Paliu family were examined. The three N sources viz ammonium sulphate granular urea 2.9mm and forestry-grade urea 7mm were applied at rates of 0.4 0.8 and 1.2 kg of N per palm per year. The results show that urea gave comparable response in yield to ammonium sulphate as well as a significant linear response to N rates. FFB yield was significantly affected by the method of application. Burial of fertilizers at two times a year gave inferior results and required two or three times more fertilizer to achieve comparable yield to overall application at 2 times a year or broadcast in the palm circle at 4 times a year.
