Abstract: Furrow irrigation is the most widely practiced form of surface irrigation in the central valley of Ethiopia for cultivating different crops. This study was undertaken at Melkassa Agricultural Research Center to assess the effect of furrow length and flow rate on irrigation performance and maize yield using Melkassa II maize variety as a test crop. The experiment was designed in split plot with three replications, where furrow length used as the main plot and flow rate as sub-plot. The treatment includes furrow length of 16m, 32m, and 48m and flow rates of 0.52l/s, 0.79l/s, and 1.05l/s. The ranges of mean yield gained from furrow length and flow rate were 5.66 to 5.81ton/ha and 4.98 to 6.8ton/ha respectively. The effect of furrow length and their interaction with flow rate on yield were not significant (P=0.01) but the flow rate has significant effect on yield (P
