Abstract
Coffee pulp, a by-product of the processing of picked coffee cherry in the coffee factory, is known to have comparatively a higher content of potassium than that of the other macronutrients. If applied to coffee growing soils indiscriminately, it would have more-or-Iess the same effects as Napier grass on coffee quality and the soil's fertility status (Blore, 1965 and Mehlich, 1965). Moreover, unless adequate disposal means are provided in the factory, the accumulation of coffee pulp (particularly in the co-operative society factories) is a likely consequence and this, among other things, may be a health hazard and waste of coffee drying space in the factory. In order, therefore, to explore an economic means of disposing coffee pulp two experiments were initiated in 1967 to test whether coffee pulp in combination with inorganic fertilizers containing N, P and K could effectively be used as manure in maize growing, thus producing grain for consumption or feed for cattle and the Stover for mulch in coffee.
