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.

(Location: IWMI-HQ Call no: 631.7.6 G732 INT Record No: H015)
The paper describes scientific management of irrigation for the seedbed, land preparation, and growth periods of lowland rice. The land preparation period is found critical for canal design, and appropriate formulas are discussed relating the area to be prepared with the duration of the period and available water supply. Water management for the crop after transplanting is also defined through formulas. Experience from Taiwan is used to estimate rotation intervals under conditions of variable soils, sources of water, and seasons.

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.

This paper describes the process of matching cropping systems to available irrigation water supply. The Penman and the Jensen-Haise methods for calculation of potential evapotranspiration (Etp) from climatic parameters are presented, along with methods for calculating crop water requirements once Etp is known. The principles of determining irrigation water requirements of single crops and of combinations of crops is given. Examples given are from Pakistan. Due to the complexity of the process a simulation model was developed to match cropping systems to water supply. Model structure is described and examples are shown for both single and multiple cropping systems. Details of the methods of calculation along with program documentation and listings are appended.

Tank irrigation systems are very common in South India, accounting for about one-third of the irrigated area. Most of these tanks are about 100 years old and the performance is not satisfactory due to poor operation and maintenance. Many of the tanks were neglected and lost much of their original storage capacity due to encroachment, siltation and inadequate maintenance. To study the management of tank irrigation systems and to identify investment opportunities, Tamil Nadu Agricultural University and the University of Minnesota have been analyzing ten tanks in Ramanathapuram district of Tamil Nadu. Farmers depended heavily on the groundwater for supplementing tank water supplies. About one-third of their water supplies came from wells. Most of the farmers served by tanks grow only one paddy crop. Farmers with inadequate water supplies adopted a network of strategies ranging from heavy fertilizer applications to a 4 to 7 day irrigation rotation to save their crops. This study identifies a number of key tank characteristics that effect crops. These characteristics were related to the inadequate tank water supplies and the poor distribution of available supplies.
