Summary
Maximum germination response and root + shoot yields of Acacias were obtained at daily irrigation. Any deviation from daily irrigation resulted in variations of performance (germination and growth yield) between the six Acacia species studied. Species of relatively dry habitse.g. A. nubica andA. seyal were more sensitive to water supply compared with those of relatively wet habitatse.g. A. nilotica andA. albida. This was reflected at the establishment phase by the greater production of root + shoot yields of species of drier zones than by those of wetter ones. It is concluded that variations in water supply may account for species adaptation and distribution in semi-arid zones.
