Number of Leaves and Leaf Area: As shown in Fig. 2. Leaf area was decreased respectively in cassava, the best result was at T25. Inhibition of both cell expansion and the production of cells contributed to losses in leaf area, depending on the developmental stage at which a leaf was stressed. Generally, it was observed that growth resumes after a mild, short-term stress, but growing cells may not expand fully to the size of controls and water stress may cells per leaf [26].
