Abstract
The main coffee soils in Kenya have been found to be low in nitrogen (Pereira and Jones, 1954). Past studies have confirmed positive coffee yield responses to nitrogen fertilizers (Oruko, 1977; Michori 1981; Njoroge, 1985 .. 1985b; Njoroge and Mwakha, 1985 .. 1985b and 1986). A need exists to consider fertilization in relation to changes in plant population (Hux1ey, 1968). Information to guide application of optimal nitrogen fertilizer for high density coffee is lacking the objective of this study was. Therefore, to determine the influence of nitrogen fertilizer and plant density on growth and yield of Arabica coffee
