Abstract

To evaluate the different Water Deficit levels on yield, yield components and water use efficiency of FORAGE MILLET (Pennisetum americanum) and sorghum (Sorghum bicolor); an experiment was conducted in agricultural research station of Miyaneh branch, at Islamic Azad University in 2010. Experimental design was split plot based on Randomized Complete Block in three replications. The main plots were three irrigation levels (33.67 and 100 percent of water requirement), sub plots were species (forage sorghum and millet).The results showed that the effect of irrigation, plant and their interactions were significant in %1 level on total fresh and dry yield and water use efficiency. The results showed that the total fresh and dry yield for without stress treatment, was 27.1 and 7.0 ton/ha per each harvest, respectively. In moderate WATER STRESS, yield reduction was 20% but in severe stress we showed 63% yield reduction, which showed that high resistance to plants against drought stress was moderate. The highest water use efficiency (0.98 kg dry matter per kg water) related to moderate stress treatment and CV. Notrifeed millet. Treatment of severe stress in sorghum had the lowest water use efficiency (0.65 kg dry matter per cubic meter of water) with about 34 percent lower compared to superior treatments. Ability of millet in water utilization for dry matter production was higher than sorghum. The results also showed that the water use efficiency and fresh and dry forage yield had significant and positive correlation in %1 probablity level. In addition there was a significant and positive correlation between fresh and dry forage yield, Plant height, leaf number, stem diameter and number of tillers as well as total fresh and dry yield of forage and WUE in millet was greater than sorghum.
