Water resources of Balochistan, an arid province of Pakistan, are extremely scarce and limited. It is highly imperative that these resources be used most judiciously to ensure sustainable agriculture development and productivity. This, in turn requires knowledge of crop water requirements (CWR) in various agro-climatic zones of the province. Lack of this information often results in farmers over or under irrigating their fields with consequent loss in yields and production. Various agencies in the country have determined CWR values for the Indus Basin; however, for Balochistan the water requirements of various popular crops have not been estimated.
