Description

Drought stress is a major constraint to the production and yield stability of crops. Rice (Oryza sativa L.) is considered as a drought-sensitive crop species. Within this species, there are considerable varietal differences in sensitivity to this environmental stress. An experiment was conducted at the Green House of the Department of Applied Ecology, Abubakar Tafawa Balewa University (ATBU), Bauchi State of Nigeria during the months of September to November 2018 to evaluate 3 rice cultivars for drought tolerance in their tillers, height, shoot and root biomass. The experiment was laid out in a complete randomized design with four replications. The result showed that with increasing level of water stress, performance in all the varieties was decreased, except Faro 4L which was tolerant to drought. Also, Faro 52L showed some tolerance in its tillers, root and shoot biomass. Therefore, two rice cultivars (Faro 4L and Faro 52L) showed good performance under drought condition, while Faro 44L was not tolerant.
