Abstract: 
In order to investigate the yield and water use efficiency (WUE) of forage millet under 8 irrigation regimes, a two year field experiment was conducted in 2000 and 2001 growing seasons at Ardakan Agricultural Station, Yazd. Accumulative pan evaporation (APE) was measured in order to determine the time of irrigation. The treatments I1, I2, I3 and I5 were irrigated when APE reached 90, 120, 150 and 180 mm, respectively; I5 and I6 were irrigated when APE reached 150 and 180 mm till the first cut respectively, and afterwards like I2 treatment; I7 and I8 were irrigated when APE reached 120 mm from establishment to first cut and then irrigated when APE reached 150 and 180 mm, respectively. The treatment effects were significant in the year 2001. On the average, treatment I4 with 9.2 kg/m3 and I1 with 6.8 kg/m3 had the highest and the lowest WUE, respectively. The fresh and dry yields of treatment I5 were respectively 24.9 and 6.6 ton/ha in the year 2000; and 18.2 and 4.5 ton/ha in the year 2001. On the average WUE of treatment I5 was 8.9 kg/m3.
