Water supply is the major yield-limiting factor in dryland areas and must be more efficiently used if increased crop production is to be achieved. Correct tillage and moisture conservation practices will increase soil moisture and reduce losses from evaporation and transpiration, and correct crop management practices will make the best use of water stored in the soil and precipitation. Research is in progress in Central Anatolia to determine the cultural practices best suited for such an environment. Weed control is one of the most important components of a management package because weeds compete with crops for the limited water. Weeds can be controlled through proper seedbed preparation, tillage and seeding methods, which affect stand establishment and thus ability to compete, and through crop rotations. Fertilization and selection of crop varieties also have an effect on weed growth and density. The management of fallow and its possible reduction by 33-50 percent is also important in relation to weed control and water use efficiency
