The study was carried out during 2004–2005 season in four locations at Taiz governorate (Beni Hammad, Alshaobh and Almasha'er) to know the actual nutrients needs of coffee trees (Coffea arabica L.) under Yemeni soil conditions. It included 13 fertilizer treatments and the control {three levels of nitrogen (N1, N2 and N3) (40, 60 and 80 g N/tree), one level of phosphorus (P) (20 g P2O5/tree), cattle manure (B) (5 kg/tree), two treatments of sprayed micronutrients (Micro-1 and Micro2-), and the combination interactions of those nutrients sources}. It was executed under rainfed and supplementary irrigation system using the randomized complete block design (RCBD) and three replications with one coffee tree as an experimental unite. The treatments (B+N1), (P+N2), (N3) and (N2) showed significant superiority of tin dry fruits production over the control. The overall average production increased by 76.64%, 64.23%, 56.7% and 54.7% have achieved a ratio of net profit of 158, 122, 193 and 201% respectively. The cattle manure and phosphorus did not show significant productivity increase. Results also showed a low percentage of nitrogen and a high percentage of phosphorus and iron in addition to an annual soil depletion of macro and micro nutrients of about 83 kg/ton of dry coffee fruits.
