Water is an important factor for mango production in Southern Coastal Central Vietnam (SCCVN). The experients on the effects of irrigation technologies on yield of mango crop on sandy soils were caried out in Binh Dinh province with following treatments: (1) Irrigation based on farmer’s traditional practice; (2) Irrigation based on farmer’s traditional practice following mini-pan; (3) Drip irrigation following mini-pan; (4) Sprinkler irrigation following mini-pan. Resutls of study identiíìed that the drip irrigation obtained the highest economic efficiency which increased yield by 26 - 32%, saved 46 -70% amount of water and increased 45.7% profit in comparison with the traditional method. The irrigation following mini-pan also obtained high economic eíRciency, this method increased fruit yield of mango by 9 -14% and net profit to 40 % while reduced 34 - 70% amount of irrigated water compared to the mere farmer’s traditional practice.
