Abstract: Soil fertility depletion due to soil erosion and nutrient leaching caused by heavy and continuous rainfall is one of the major causes for declining of soil productivity and crop yields in Masha district of south-western Ethiopia. Soil Hence, a field experiment was conducted in Belg and Meher seasons at Abelo area, Masha district, south-western Ethiopia, to determine the effect of combined application of cattle manure (CM) with inorganic nitrogen (N) and phosphorus (P) on potato tuber yield, and selected soil physico-chemical characteristics. The treatments comprised of combinations of three rates (2.5,5, 7.5 t ha-1) of CM with 25%, 50% and 75% of recommended rates of mineral NP, respectively. In addition, 100% recommended rate of mineral NP (165kg N ha-1 and 137kg P2O5 ha-1) and zero rates were used for comparison. The experiment was laid out in a randomized complete block design with three replications.
