Land suitability evaluation has been determined for irrigated wheat, sugarbeet and alfalfa in an area about 52100 ha in Nagadeh region in West Azarbaijan Province. In order to have more confident soil data, particularity to control the old soil map of the area , a new soil survey studies were done.Soils were classified based on soil taxonomy (1998) and 16 families and 34 phases were identified . Climatic data from Nagadeh meteorologicl station have been used for climate evaluation of crops . Based on yield coverage and climatic conditions, wheat, sugarbeet and alfalfa have been considered and compared in the present land suitability evaluation on the basis of irrigated agricltural system. In this region, the most important limiting land characteristics have appeared to be topography and flooding. In surveyed area the climatic classes are suitable(S1) for wheat and sugarbeet and moderately suitable(S2) for alfalfa and barly,Analysis of rainfall and ETO data reveals that the growing period is about 94 days, starting on october 10 until april1. Comparing the two parametric methods (ie.storie and square root methods) for determination of land indexes for three crops, in all methodes the land indexes for wheat was always higher than those for sugarbeet and alfalfa, the square root method was considered to be more realistic for land suitability evaluation in the studied areas .
