This study was conducted to evaluate drip irrigation as a potential alternative to furrow irrigation in sugar-cane at Mupapa Settlement Scheme in Zimbabwe. The study addressed the water scarcity problem being experienced in the Sugar-cane Estates of Zimbabwe. It investigated the potential of using drip irrigation, which has higher water use efficiency. Twenty plots were arranged in a completely randomized design to determine fresh weight and sucrose content. The financial implications of the systems were evaluated using Net Present Value, Benefit Cost Ratio, and Internal Rate of Return. Yield and sucrose content results were analyzed using Genstat Package. The results showed a significant difference (p<0.05) in sugar-cane fresh weight and sucrose content between drip and furrow treatments. Drip had a lower fresh weight value of 114.5 t/ha compared to 134.95 t/ha for furrow systems in 2008. Sucrose values of 57.75t and 66.5t were obtained for drip and furrow, respectively in the same year. In 2009, there was a slight increase in fresh weight of 2.0t and 1.25t for drip and furrow systems, respectively. Sucrose content increased slightly by 0.15t for drip, and 0.2t for furrow system. For both treatments Benefit Cost Ratio was greater than zero and Net Present Value was positive, showing that they are profitable and viable projects. The Internal Rate of Return for drip project was 7.46% compared to a value of 26.66 % in furrow irrigation. Thus, more years are required to cover the initial costs incurred for drip irrigation.
