Abstract
The susceptibility of pearl millet to soil water deficits at different times of growth was determined in field experiments conducted over 2 years. Grain yields and yield components were expressed as ratios of stressed to non-stressed treatments. Where water deficit was imposed earlier in crop growth and then relieved, the time of termination of stress from flowering determined the extent of grain yield loss. Water stress relieved at anthesis or early grain filling had little adverse effect on the grain yield because additional tillers produced panicles. This response by tillers was less evident and grain yields were more severely reduced when water stress was not relieved until after flowering. When stress was imposed late in crop growth and not relieved, the time of initiation of stress was directly related to the extent of loss in grain yield. Thus susceptibility to mid-season drought stress was related to the time stress was terminated and in late-season drought to the time stress was initiated.
