Growth of Millet [Pennisetum glaucum (L.) R. Br.] and Sorghum (Sorghum bicolor (L.) Moench) Plants under Water Stress Conditions

Water stress effect on millet and sorghum plants growth was investigated in this work. Grains were germinated for 7 days in Petri dishes. Plants obtained were transplanted into pots, with 60 repetitions per species. For 6 days, they received 100 ml of water before being divided into four batches corresponding to four treatments (100, 50, 25 and 10 ml). An increase in water stress led to a reduction in size of both plant species and leaves number produced, while root system growth was recorded. Millet plants suffered more from depressive effect of water stress than those of sorghum. Therefore, millet is more predisposed to respond to drought than sorghum.
