Adequate supply of soil water is essential for growth and development of the maize. Climate change can cause erratic rain patterns and resulting to excess water moisture stress (EMS). EMS is one of the major obstacle for sustainable agriculture. the present investigation aims to investigate the effects of the seven-day EMS condition in different white maize genotypes, and to determine the sensitive growth stage that negatively affects the growth and yield potential of maize and morphological traits of maize conferring tolerance to EMS.
