| DEFINITION |
"Drought sensitivity is highly interactive with crop phenology, plant growth prior to stress, and timing, duration, and intensity of drought stress. For many soils, it takes at least 2 rainless weeks to cause marked differences in drought sensitivity during the vegetative stage and at least 7 rainless days during the reproductive stage to cause severe drought injury. Leaf rolling precedes leaf drying during drought. Repeated ratings are recommended through progress of the drought." [IRRI:SES] |
