A Fertilizer Leaf Spray for Coffee.

Abstract

A trial was conducted on mature Coffea arabica at Aiyura to determine the effects on yield of fertilizer leaf sprays. 'Sea Magic SM-3' was compared with Urea and a compound fertilizer and the trial extended over three years from 1961 to 1964. The only treatment to give significant yield increase was the compound fertilizer, 'Nitrophoska Green' with trace elements, applied to the ground.
