Standard recommendation for fertilizers, 1991. Technical circular No. 59
1991
Presents fertilizer recommendations in coffee, based on leaf and soil analysis. These include nitrogen, phosphate, potassium, compound, organic manure and foliar feed fertilizer types. Their conditions of use and application rates is discussed. The study also shows that coffee yield increase was realized at an application rate of 5-10 litres/ha of NPK foliar feeds. In closely-spaced coffee, fertilizer application rates in gm/tree rather than in kg/ha on annual application basis is recommended. With nitrogen fertilizers, an application rate of 200 kg/N/ha per annum is also recommended in order to provide optimal benefit to coffee
