Drip irrigation technology with the goal of overcoming the limitations of traditional irrigation such as proactively supplying water to plants according to each growth period at a high level of accuracy, occupying less arable land. With drip irrigation technology, water is supplied directly to the soil containing the plant's roots, reducing losses due to infiltration and evaporation, saving 20-30% compared to traditional irrigation technology. According to the research results on sugarcane in Tuyen Quang, it shows that for each hectare of sugarcane planted with drip irrigation technology, the production cost increases from 10.5 - 12 million VND/ha/year, but the yield increases by at least 40%. Therefore, the profit of drip-irrigated sugarcane area is from 24.5-26.3 million VND/ha, higher than traditional irrigation from 8.3 - 10 million VND/ha. The efficiency of 1 VND of investment capital of the irrigation model is 1.53 - 1.58 times while the traditional irrigation is only 1.47 times.
