To compare the water requirement (WR), water productivity (WP) and economical water productivity (EWP) of wheat and rapeseed in wet years in western Iran, an experiment was carried out in Sarab Changai Agriculture Research Station (Lorestan province) in 2001-2002. Statistical analysis of resulted data showed that the differences between mean WR, WP and EWP of two plants were significant (P=0.99). Mean WR (Irrigation + effective rainfall) of wheat and rapeseed were 5000 and 6590 m3 ha-1 respectively. Mean WP of wheat and rapeseed were 1.64 and 0.60 kg m-3 and their EWP were 2128 and 1508 Rials m-3 respectively. As a result cultivation of wheat (as a winter crop) is preferred to over rapeseed because of its lower WR and higher WP and EWP.
