Abstract
A pot experiment was conducted to study the effect of water stresses on the growth features of maize (Zea mays L.) cultivars viz., Amper pop, Bomali, Suvra, Sadaf and Sayar II. The treatments were with soil moisture (control), constant drought, constant saturated soil moisture and waterlogged conditions of soil. The growth features were plant height, base diameter, leaf number and total life span of the plants height, base diameter, leaf number and total life span were severely affected by drought and waterlogged conditions in all the test cultivars with significant effect in drought than under waterlogged. There were little adverse effects in saturated soil moisture condition. Within the treatment, different cultivars suffered at different magnitude. Amper pop was more resistant to both drought and waterlogging as compared to other cultivars.
