A Study was conducted for that important saline area in Iran and nonattention to microelements for growth of sugarbeet in this area. The objective this experiment was for determinate of the best method for consumption microelement(Fe, Zn, Mn and Cu) in saline area for sugarbeet cultivation. This study was conducted in Rodasht-Esfahan station(RES) during 2006-2007. Salinity of soil were 6.68 and 8.40 dS/m respectively and amount of soil microelements(Fe, Zn, Mn and Cu) were under critical level. Soil at the RES is classified as a havey clay(Fine, mixed, thermic, Torri Fluvents). In this study 14 treatments of microelement were used in split plot design with four replication. Main plot were two level of 4, 10 dS/m water quality and subplot were sixth management of consumption microelement with plus check treatment. Treatments of cosumption management consist of 1) two level of cosumtion of broadcast sulfates(Fe, Zn, Mn and Cu) 25 & 50 percent highter from normal condition with two time foliar(1- after thining 2- after 16 leaves stage befor rapid top growth) . The result showed that cosumption microelement fertilizers increased sugar yield(SY) white sugar yield(WSY). Alone Consumption of broadcasting microelements wasn,t enough for increase of root yield(RY) , SY and WSY. Broadcasting with plus of foliar increased RY, SY and WSY. One time foliar with two time foliar hadn,t different significant effect on RY, sugar content(SC) and WSY. Therefore it was recommended broadcast sulfate(Fe, Zn, Mn and Cu) 25 percent highter from normal condition , plus one time foliar(after thining) in saline area.
