The Levels of Macro- and Micronutrients in the Beans of Cacao (Theobroma Cacao L.) in relation to Shade, Fertilizer, Irrigation, and Season

The levels of nutrients in ripe beans collected over a period of 16 months from a field trial were not affected by shade and irrigation treatments, but addition of fertilizer increased the levels of phosphorus and manganese and decreased the levels of copper and molybdenum in the beans. The levels o...

Description
Summary:The levels of nutrients in ripe beans collected over a period of 16 months from a field trial were not affected by shade and irrigation treatments, but addition of fertilizer increased the levels of phosphorus and manganese and decreased the levels of copper and molybdenum in the beans. The levels of nutrients in the beans did not vary appreciably throughout the period. Potassium was the only element which showed a systematic seasonal variation of content, with the highest level in March and a steady decline to the lowest level in October. The mean ash content and levels of twelve nutrients in the beans are reported, as well as the seasonal maxima and minima.
