Mulching with different irrigation practices is one of the techniques to improve soil productivity and water use efficiency. The increasing demand of water in the region highlights the need to introduce low-input and water saving technologies for agricultural sustainability and crop production, mainly in semi-arid region. The experiment was conducted at the research station of Mehoni Agricultural Research Centre (MehARC) in the Raya Valley, Northern Ethiopia, conducted during 2017-18 and aiming to evaluate the effect of mulch types on yield and water productivity, to determine the effect of furrow methods on yield and water productivity and to analyze and evaluate different techniques that enhance water productivity of maize yield. The experiment was laid out in a split plot design and consisting of three types of furrow irrigation methods (alternate, fixed and conventional furrow irrigation methods) in the main plot and two mulch types and no mulch with three replications were used as two factors to evaluate the yield and yield component including water use efficiency of maize in split-plot design. Different types of irrigation method and mulching types were significantly (p<0.05) affected all the studied parameters of yield and yield components of maize at the study site. Significantly a higher maize grain yield and yield component was recorded from conventional furrow irrigation method than alternate and fixed furrow irrigation method and higher water productivity was obtained from alternate furrow irrigation method.  The study area water is a limiting factor and alternate furrow irrigation method could be practiced with plastic mulch for improving maize grain yield and water productivity.
