Experiment aimed to compare the nitrogen, phosphorus and potassium contents in the leaves of three cultivars of Long Cayene Pepper (Capsicum annuum L.) and those as affected by ten fertilizer formulations to set up the criteria for determining the optimum fertilizer formulations. The experimental design was split plot with three replications, using ten fertilizer formulations as the main plot and three cultivars of Long Cayene Pepper as the subplot. The experiment was conducted at Lampang Agricultural Research and Training Center from 22 October 1996 to 11 April 1997. The results showed that the level of nitrogen content in the three cultivars was higher than the standard level at the vegetative stage but it was within the standard level at the fruit setting stage. In contrast, the phosphorus content at both stages was lower than the standard level whereas the potassium content was within the standard level at both stages. The fertilizer formulations affected the nutrient content in the leaves of three cultivars of Long Cayene Pepper. The formulations of 15-7.5-7.5, 15-15-15 and 15-30-30 kg. N-P2O5-K2O/rai produced the nitrogen content within the standard level at the fruit setting stage. In case of the phosphorus content and the potassium content, it was found that all of the fertilizer formulations produced lower phosphorus content than the standard level at both stages whereas the formulations of 15-7.5-7.5 and 15-15-15 kg.N-P2O5-K2O/rai produced potassium content within the standard level at the vegetative stage, but, at the fruit setting stage, all of the formulations could produce it within the standard level.
