"A conservative pattern of water use, rather than deep or\r\nprofuse rooting, is critical for the terminal drought tolerance\r\nof chickpea"^^ . "Chickpea is mostly grown on stored soil moisture, and deep/profuse rooting has been hypothesized for almost three\r\n decades to be critical for improving chickpea tolerance to terminal drought. However, temporal patterns of water\r\nuse that leave water available for reproduction and grain filling could be equally critical. Therefore, variation in water\r\nuse pattern and root depth/density were measured, and their relationships to yield tested under fully irrigated and\r\nterminal drought stress, using lysimeters that provided soil volumes equivalent to field conditions. Twenty chickpea\r\ngenotypes having similar plant phenology but contrasting for a field-derived terminal drought-tolerance index based\r\n on yield were used. The pattern of water extraction clearly discriminated tolerant and sensitive genotypes. Tolerant\r\ngenotypes had a lower water uptake and a lower index of stomatal conductance at the vegetative stage than\r\nsensitive ones, while tolerant genotypes extracted more water than sensitive genotypes after flowering. The\r\nmagnitude of the variation in root growth components (depth, length density, RLD, dry weight, RDW) did not\r\ndistinguish tolerant from sensitive genotypes. The seed yield was not significantly correlated with the root length\r\ndensity (RLD) in any soil layers, whereas seed yield was both negatively related to water uptake between 23–38 DAS,\r\nand positively related to water uptake between 48–61 DAS. Under these conditions of terminal drought, the most\r\ncritical component of tolerance in chickpea was the conservative use of water early in the cropping cycle, explained\r\npartly by a lower canopy conductance, which resulted in more water available in the soil profile during reproduction\r\nleading to higher reproductive success."^^ .
