The results of EWUP studies at each of three locations in Egypt: El-Mansuriya, Kafr El-Shiek and El-Minya, to characterize the conventional farm irrigation systems used by farmers in each area are summarized. The method used is surface gravity flooding of small, flat basins or small basins with short furrows. Numerous irrigation field trials on farms at the three EWUP study areas have been conducted. The practices tested included precision land levelling to dead level; level border strip or level long furrow irrigation system design; and teaching and advising farmers concerning improved on-farm water management practices in the use of the improved systems. Results were found to be highly successful when the spatial and temporal variations in farm irrigation system design factors were properly accounted for. A significant factor is the need to continue working with the farmer after system construction, teaching and advising him of improved management practices with the new systems. EWUP experience has shown that when farmers are well advised in using the new systems improved results are significant.

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.

Water management activities within the National Irrigation Administration are outlined, with special emphasis on those adopted by the Upper Pampanga River Project. This project, not yet complete, will have reservoir storage for the dry season crop. The system of rotational irrigation being implemented in the project area is described, and its problems are discussed. The problems include improving the effective use of rain water, and organizing and educating farmers for more efficient water use. The findings are supported with water-use data from a pilot area.

A research project was carried out on large sites within irrigationsystems to determine the benefits of irrigation to yields of lowland rice. Datawere collected under farm level conditions to establish yield response to days of moisture stress. A model was then developed and employed to relate irrigation, rainfall and water-use parameters to days of moisture stress, and thus to yields. Although yield benefits due to irrigation were substantial for both seasons, they were seriously depressed because of imperfect irrigation, particularly in the dry season. Neither the height of paddy bunds nor the amount of rainfall in the sites were of major consequence to grain yield. Considerable variation in water-use was observed among the sites, but it was generally found that sites with low water-use efficiencies showed the greatest yield benefits, and vice versa.

The present system of pricing of irrigation water in the gravity irrigation systems of the Philippines results in inefficient allocation and use of water. Furthermore, the low price of water results in the capitalization of irrigation benefits into land values. Hence, landowners are the major beneficiaries. Gradually increasing the price of water so that it is more in line with its opportunity cost under optimum management would improve the economic efficiency of water use and encourage the collection of government revenues for further public investment. As soon as practicable, water should be metered directly to farmers' paddy fields and the water charged based upon the amount actually diverted.

The improvement of the economic and social well-being of the Egyptian farmer through technological change in on-farm water management is a primary objective of the Egypt Water Use and Management Project. Analysis of the use of resources on Egyptian farms is an essential part of assessing the economic efficiency of water use. Irrigation water interacts with other inputs. The best use of these inputs relative to each other, their allocations between alternative enterprises, and between farms, is a primary consideration to improvements in on-farm water management. It is also important to analyze the institutional constraints imposed on the farmers which limit their ability to achieve the most profitable allocation of water and associated inputs. The economic analysis in the Egypt Water Use and Management Project revolves around a farm record system. The farm record system was developed as a tool for use in monitoring and planning on-farm water management alternatives. The system provides data to evaluate the relative contributions of alternative enterprises to farm income, to delineate the production activities for each enterprise, and to determine factors which limit operating decisions. An analysis of the factors which impact on the economic and social well- being of the farmer as a result of the farming system at each of the project sites indicated that the importance of share rental agreements for land is increasing, cropping patterns are not static, crop productivity has increased over time, and the relative importance of livestock has increased. An analysis of the returns to water has decreased over time and, in several cases, was negative.

The purpose of this report is to document the actual irrigation practices of the farmers in two Egypt Water Use and Management Project (EWUP) areas, Abyuha in El-Minya Governorate and Abu Raya in Kafr El-Sheik Governorate. Data on the farmer practices were abstracted from the EWUP R4 Farm Records for the 1979-1980, 1980-1981, and 1981-1982 record years. The study case data were divided into 15 day periods with the winter closure period eliminated from the analysis. A comparison of the actual planting and harvest dates with the expected dates indicated that the actual dates were later than the expected dates by about two weeks. A comparison of the actual number of irrigations with the expected number of irrigations indicated that farmers apply close to the expected number or fewer. The analysis indicated that irrigation gaps for some crops range as high as 89 days. The aggregate demand on the delivery system in both study areas tended to be highest in the periods immediately before and after winter closure and the summer periods, June through September. Comparing the measured water discharged into the Abyha canal with an estimated demand for selected periods indicated that relative fluctuations in the delivery of water correspond fairly well to the demand during the same period. A comparison of the measured water discharge into the Om Sen canal with an estimated demand for selected periods indicated excess delivery of water during the winter periods, periods where shortages of water delivery could have occurred, and a general lack of correspondence of the fluctuations in discharge to the fluctuations in demand.

The importance of managing water once it arrives at the farm site is the central issue in this report. The study limits its focus to the technical side of on-farm water management.
