Flame spectrophotometric determination of Potassium, Sodium and Magnesium in coconut water.

Abstract

The use of coconut water analysis as a guide to the nutrition of the coconut palm was first investigated in Ceylon by Salgado (1, 2). His work has been confined mainly to potassium estimations and shows that the uptake of potassium, as measured by the concentration in the coconut water, is related to the degree of response to potassic fertilizers and to the yield of coconuts in Ceylon. Cassidy (3) has also attempted to relate the potassium content of the nut water with the poor condition of palms in Fiji, but came to the conclusion, based on Salgado’s figures, that potassium deficiency was not likely to be a factor in their decline.
