The most profitable use of resources on a typical Egyptian farm is analyzed in view of resource, institutional and government policies. The linear programming model of a farm management decision problem is based on an average sized farm found in a survey of 50 farms in Kafr El Shiekh. By solution of the model one can observe the interdependencies. Further, changes in the method of irrigation or in the government's system of water supply are evaluated with the model. Four sets of policy alternatives are examined. The base run reflects existing policies, a second option includes only administered prices. Additionally, a free market alternative is tested and finally, a free market coupled with a system to charge farmers for the delivery of water. Results show that existing policies do not greatly distort the optimal mix of enterprises but it is likely that farmers would have incentive to achieve higher crop yields under different price policies. As yields associated with higher commodity prices are achieved, farmer's incentive and ability to adopt improved water management practices would be enhanced.

Experiments conducted for several cropping seasons on the montmorillonitic Maahas clay soil at the IRRI farm demonstrate that continual flooding is not essential for high grain yield but flooded rice can tolerate at least 15cmif the improved varieties are grown. Tall varieties like H-4 has less adaptability under wide range of water management conditions than semidwarfs like IR8. With adequate water supply, 5 to 7 cm of water is desirable on most soils for best weed and insect control with granular chemicals, forhigh nutrient availability, and for minimum losses of nutrients from fertilizer and soil. If rainfall does not provide supplemental water, irrigation intervalslonger than 8 days reduce grain yield under a rotational irrigation system. Varieties like IR5 that have a long growth duration were least sensitive to moisture stress imposed by long irrigation intervals. This is because IR5 will generally recover from high moisture stress for a short period or low moisture stress for a long period. An experiment with IR20 indicates that the furrow irrigation of nonpuddled soil does not provide more efficient water use in rice compared with rice grown on puddled lowland soil.

The EWUP conducted an irrigation research and development program from 1978 to 1984 in the Abu Raya area served by the Daqalt Canal in an effort to improve irrigation water management. Using an interdisciplinary effort, the program included the design, construction and operation of the Daqalt Canal system to deliver water to all farms in sufficient quantity at appropriate times to meet all water needs; to deliver water at an adequate and equitable flow rate and head and to minimize surface losses to drains. The original system was designed, constructed and operated under certain physical and operational assumptions that would minimize use of water while maximizing crop yields for all individual users. The report describes the physical characteristics of the existing system including water supply, canal structures, canal and mesqa surveys, soil conditions, crop patterns, water table levels, on-farm irrigation and water delivery requirements. The socio-economic characteristics of the existing system were also evaluated to assist in developing an equitable water user management program. The Daqalt Canal does not meet its original objectives due to water shortages, inadequate and inequitable flow rates and heads, and large surface losses to drains. These problems are caused by ineffective physical structures operation, conflicts existing with irrigation timing preferences, and poor canal maintenance. As such, the performance of the system falls short of that desired due to incorrect assumptions and improper management, and the entire water delivery system requires renovation within the context of the larger irrigation system. It is recommended that a complete hydraulic model of the existing Daqalt system should be developed under the constraint of available water levels in the Mit Yazid Canal, and the design re-evaluated in light of this model. The renovation process should continue, and water users themselves amalgamated into the design and operation of the water management plan.

The economic history of most riverine and swampy communities does seem to suggest that perennial crop production is very much entrenched in their social economic fabric. But its potential has largely been underestimated. Thus,the introduction of irrigation technology tends to be seen as a new way of crop production. As such, intervention measures initially tend to be designed as pilot projects, so as to generate enough experience and knowledge before their widespread diffusion. However, experience with most community-oriented pilot projects seem to show that if the interventions are not based on the intended beneficiaries' own past experiences, the introduction of new technology tends to exacerbate the production risk of the participants. From the experiences in Gwembe Valley, Zambia, it is argued that irrigation interventions in the small holder farming sector have to be geared to the strengthening of the existing production virtues, as well as the weakening and elimination of the risks.
