| Abstract | ||||
| Water management has become a crucial issue particularly in arid and semi arid zones that are characterized by scarce, or limited, water resources. Egypt is no exception from other countries that lie in these zones. Unless strict measures are taken to maintain sustainability of irrigation. we will face a water problem in the near future. it is therefore deemed necessary that Egypt find out ways, and techniques to develop, control, manage, and use their water resources more efficiently in order to meet the growing demand for water. Two field experiments were carried out during summer seasons of 2002 and 2003 to study the effect of irrigation in two directions and cut back stream on maize yield and water saving at El Karada water requirement, Research station, Kafer El Sheik Governorate, Water Management and irrigation Systems Research institute, National Water Research. The treatments of irrigation in two-direction and cut back stream when water reached the end and 90% of the furrow was the best individual or combination treatments for obtaining maximum grain yield results indicated that — water could be saved as an average of 268.64 maffed (9.66%), 567.45 maffed, (20.54 %) and 778. malted. (28.18%) with applying irrigation water under cut back stream when water reached the 90%, 80% and 70% of the furrow length respectively. - The water consumptive use increased as the applied irrigation water increased. - irrigation application efficiency and water utilization were the highest using irrigation in two directions and cutback stream when water reached 70% of the furrow length, while the highest crop water use efficiency was found with cut back stream when water reached 80% of the furrow length. - The maximum values of total income, total return, water productivity and economic efficiency obtained from plants grown under irrigation in two directions with cut back stream when water reached 90% of the furrow length. Results help to suggest that using cut back stream when water reached 90 % of the furrow length can save water irrigation with amount of (268.64 mailed.) 15.513960 million m [area (57750 feddan) under Kafer El sheikh conditions. These quantities of saving water enough to cultivate area of about 5601 97 feddans under kafer el shiekh conditions | ||||
