Abstract

The coconut palm, Cocus nucifera L., is one of the most beautiful and useful palms in the world. It provides a variety of useful products like food, fuel and timber. It is grown in India in about 1.51 million ha. Among the different coconut growing states in India, Kerala, Tamil Nadu, Karnataka and Andhra Pradesh account for nearly 90percent in area and production. The tall variety of coconut grows more slowly than the other two. After 6 to 10 years of planting, it begins to produce fruit, and even after 80 to 120 years, it continues to give yield. The tall type palm takes a year to ripen its fruit. The dwarf type, on the other hand, begins to produce fruit after one to two years of planting and grows to a height that is only about half that of the tall variety. Nutrient removal by different parts of coconut, their morphological characters, volume of biomass produced and nutrient content in biomass of both the cultivars WCT and COD. Comparing among different nutrients potassium was highly removed from different parts especially from husk in both the varieties WCT and COD. There is a need to increase the application of fertilizer dose from recommended dosage particularly potassium rich fertilizer. The biomass weight calculated also showed WCT has high biomass than COD. The nutrients in dried biomass were estimated which can be suggested to recycle these biomasses to reuse as organic manure to those plantations itself which may somewhat reduce the usage of chemical fertilizers.
