In a field experiment in Varamin Agricultural Research Center during 2003 to 2004, effects of three irrigation water regimes based on evaporation from pan class A (60, 80and 100 percent evaporation) and four fertilizer treatments (NPK, NPKZn, NPKFe and NPKFeZn) in a clay loam soil on tomato yield were studied. The experiment design was split plot with three replications using drip irrigation. Main plots included irrigation regimes and sub plots included micronutrients treatments. Results showed that the effects of main plots and sub plots and their interaction on yield and water use efficiency were significant. Results showed that use of Zn and Fe increased yield and water use efficiency significantly.In general, use of NPK+Fe+Zn and irrigation based on 100% evaporation based on evaporation pan was best treatment with 48.1 ton.ha-1 fresh yield production and 6.2 kg. M-3 water use efficiency.
