The wide range of environments in which sorghum and pearl millet are grown in semi-arid India can be grouped as variable, optimum (or near-optimum), and stored soil moisture types. Variations in specific plant responses such as phenology, leaf area development, root growth, and water-use efficiency under these three types of environments are discussed. Sorghum and millet are contrasted for their response to a variable moisture environment, and the response of sorghum grown under stored moisture during the postrainy season to terminal stress is described. Finally the role of timing, intensity, and duration of stress on grain yield is examined. Breeding and management strategies for obtaining consistently high grain yields should fully take into account specific plant responses to the basic environment to which research is directed.
