A conservative pattern of water use, rather than deep or profuse rooting, is critical for the terminal drought tolerance of chickpea.

Abstract excerpt

Chickpea is mostly grown on stored soil moisture, and deep/profuse rooting has been hypothesized for almost three decades to be critical for improving chickpea tolerance to terminal drought. However, temporal patterns of water use that leave water available for reproduction and grain filling could be equally critical. Therefore, variation in water use pattern and root depth/density were measured, and their...
