Cocos nucifera L., Coconut mite, Aceria guerreronis Keifer, Leaf nutrients


A study by leaf analysis of the nutritional levels present in coconuts (Cocos nucilera L.) in St Lucia showed that less than 2.5% of trees had adequate levels of all three major nutrients, N. P and K. N levels were generally inadequate as were P levels, though less seriously so. K levels were inadequate in some areas and excessive in others. There were some associations between nutrient status and levels of damage by the coconut mite, Aceria (Eriophyes) guerreronis. Damage generally increased with increasing levels of N. At one site, K was associated with decreasing mite damage.
