In North-West Ethiopia, a study compared drip and furrow irrigation methods for growing onion and sesame crops. The researchers aimed to see which method used water more efficiently. They found that using drip irrigation saved 33% more water than furrow irrigation for both crops. When it came to onion crops, drip irrigation was able to produce 0.9 kilograms of crop per cubic meter of water, while furrow irrigation only produced 0.55 kilograms. For sesame crops, the numbers were 0.14 kilograms for the drip method and 0.045 kilograms for furrow irrigation. This suggests that using drip irrigation could be a more effective way to grow these crops with less water in this region.
