Abstract

An experiment was conducted to determine the effect of N on growth, yield, and fruit weight to plant weight ratio (F:P ratio) of pineapple cv. Smooth Cayenne grown in the Eastern part of Thailand. Growth and yield of pineapple increased with increasing N level. The optimum rate of N was in the range of 72 to 96 kg N/rai (1kg/rai = 0.16 kg/ha) wich gave the yield from 13.5 to 14.4 ton/rai. Optimum level of leaf N at forcing time was in the range of 1.4 to 1.8%. Increasing N level decreased or tended to decrease level of leaf P,K,Ca, and Mg. There was no significant effect of N on F:P ratio of the pineapple.
