Purpose: The purpose of this study is to examine the effects of different water regimes on growth, yield attributes and water productivity of wheat production in the tropical high terrace soil of northern Sudan.
Design/methodology/approach: An analysis of variance and economic analysis were used to compare treatment means and estimate net financial return.
Findings: Our findings discovered (i) the increase in grain yield at high irrigation levels I5 and I4 compared to low irrigation treatment I1 was about 48% and 42%, respectively; (ii) crop water productivity increased significantly with the amount of water applied; (iii) net financial return increased significantly with irrigation increases until the optimal level of capacity was reached.
Originality/value: The approach and the resulting framework are original and valuable in measuring the effects of water regimes on growth, yield and water productivity of wheat.
