In order to evaluate water capture, use efficiency and productivity in sole and intercropping systems of rapeseed, bean and corn, an experiment was conducted in two growing seasons of 2007-2008 and 2008-2009 in research field of faculty of agriculture, Ferdowsi University of Mashhad, Iran. The experiment was conducted as a randomized complete block design with three replications and six treatments. Double cropping had the maximum value of this index as 0.56 mm/mm. There was superiority for double cropping in water use efficiency and productivity for species in treatments, also among treatments significantly because of its higher seed yield. The values of land equivalent ratio for intercropping combinations were more than one. This confirmed that they used land more efficient compared to sole cropping treatments from viewpoint of resources use and yield production. Rapeseed sole cropping and double cropping showed the highest values of economic productivity of irrigation water as 3.95 and 2.53 Tooman per ha production income/Tooman per ha water expense, respectively.
