A research project was conducted in order to compare transplanting and direct sowing method in sugar beet production after the last irrigation turn of barley in Karaj, Qazvin, Saven, Arak Jovaih and Mashhad regions. The experimental area in different regions were within a range of 2000-10000m2. The results of this investigation showed that the transplanting method increase the root yield by 22.16 t/ha (63.64 %) and the sugar yield by 4.45 t/ha (78.6%) when compared with the direct sowing method. Using transplanting method, 3000 m3 water corresponding to 6000m3 with 50% irrigation efficiency was saved. Additionally one herbicide and two pesticide applications and also the nitrogen fertilization before sowing were saved using transplanting technique.
