Abstract
A field study on the effect of graded levels of N, P, K, Ca and Mg on the leaf tissue concentration in oil palm was conducted at the plantations of the Oil Palm (India) Ltd. at Bharathipuram (Kerala) during 1978 and 1979. The study revealed that nitrogen fertilisation increased leaf concentration of all the elements (N, P, K, Ca and Mg) under trial and reduced the chlorine concentration. It was observed that there was a two way antagonism between the leaf concentration of K and Ca+Mg. Similarly, an antagonism of chlorine on the uptake of potassium was also observed in the present study.
