In this study, the farming practices of sweet oranges in Hung Yen have been comprehensively investigated. Our results revealed that the surface water or surface combined with groundwater was mostly used as the major irrigation method in the cultivation of sweet oranges, causing water loss, root erosion and fertilizer washout. Based on the investigation of farming practices, an improved irrigation approach was proposed by using a droplet irrigation system around the root combined with the automated fertilizing model in the orange growing area of Hung Yen. Particularly, this system was initially demonstrated to be water- and fertilizer-save, maintain the soil humidity, prevent the soil and fertilizer erosions and reduce the labor costs.
