Results are given of several studies in different regions in Iran on the effects of different rates of K fertilizer application on crop yield and water use efficiency. All the soils used in these experiments were calcareous soils. On farms growing wheat in the Karaj and Darab regions, different rates and sources of K were tested in 1999. Some 3120 and 3900 m3 water/ha were used in Karaj and Darab, respectively.
