Wahid, P.A.Kamalam, N.V.2014-07-082014-07-082007-02Indian Coconut Journal Mar 1988 p-8-12http://hdl.handle.net/123456789/3880The pattern of distribution of nutrients in the crown of coconut palm as influenced by root (wilt) disease was studied to examine whether 14th leaf is suitable for comparison of nutrient status between healthy and diseased palms. The results indicated that the nutrient levels in the leaves of diseased palms are generally higher than in healthy ones. The differences in foliar levels of nutrients are more conspicuous for leaf ranks 4 and 6 than when the nutrient levels of 14th leaf were compared. It is concluded that 14th leaf which is generally considered as the index leaf for nutrient deficiency diagnosis in coconut is not suitable for comparison of the nutritional status of healthy and root (wilt) affected palms.enArticle
