Abstract: The coconut palm (Cocos nucifera L.) is known as kalpavriksha which mean tree of heaven for its various valuable uses. Coconut palms are grown under various countries irrespective of soil and climatic factors. The yield of coconut is varied hugely which may be attributed to the level of soil available nutrients and various other factors. Soil samples were collected at 153 geo referenced points at three different depths at coconut cover and analysed for organic carbon and soil available nutrients such as N, P, K, S, B, Fe, Mn, Zn and Cu. The data on yield (nuts points^-1 years^-1) was also collected and correlated with nutrients. The study was revealed that all the above nutrients are positively correlated with coconut yield in which N, K, B, Fe, Mn, Zn and Cu were significantly correlated with yield and P & S were non-significantly correlated with yield.
