Coffee and Important Nutrients for high yields


•    improves vegetative growth
•    increases crop bearing capacity
•    increased bean size


•    roots and bearing wood development
•    early berry maturity
•    bean density

•    berry development and ripening
•    mucilage formation
•    water utilization efficiency

•    enhances bean colour (blue/green grey colour)
•    food formation

•    plant hormone
•    influences leaf size
•    intensifies flower initiation and formation

•    promotes shoot growth
•    facilitates optimal flowering and fruit setting

•    enhances aroma of the liquor

•    enhances Nitrogen metabolism

Typical Coffee NPK fertilisers are as follows:

NPK 15-5-20+te
NPK 17-17-17
NPK 20-10-10
NPK 22-6-12+S+MgO+Zn+B

Amount of trace elements are adjusted to meet local requirements.

A rule of thumb application recommendation is 250 kg/tree of NPK during the season. Normally the first application (125 g/tree) is approx 6 months before flowering and the second application (125 g/tree) is after flowering, when berries start to grow. it is also recommendable to have soil analysis every third year to fine-tune nutrient contents.

In East Africa, another general rule is that you need 1 kg of Nitrogen to be able to grow 10 kg of coffee berries. If your target yield is 2000 kg/ha of berries,  you need to apply 200 kg/ha of Nitrogen.
