The effective feeder root zone was found within the radius of0-200 cm and at depth of0-60 em from the trunk. The yielding behavior ofpalms had a direct relation to the number ofroots, nutritional status ofroot and the leaf. The bearing palms showed higher level ofleafand root N, P, K and root CRC than the poor bearing palms. The N, P and K content ofroot and root CRC were higher at the surface soil and gradually decreased with increase in depth ofthe profile.enCoconutrootsroot distributionArticle
