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.

Moisture stress often limits economical and stable yields of rainfed rice. On the montmorillonitic Maahas clay soil, grain yields of IR8 were less sensitive to growth stage at which moisture stress occurred and more sensitive to intensity and duration of moisture stress, while the tall variety, H-4,was sensitive to moisture stress during the reproductive and ripening stages as well as to intensity and duration of moisture stress. Our data indicate that moisture stress effects should be related to variety rather than to varietal type growth characteristics of rice varieties. The growth duration of rice varieties were increased with increased stress level and the relationships between moisture stress and stage of the crop may depend on growth duration of the variety among other factors. Current results indicate that soil moisture tension as low as 15 cb was enough to reduce grain yield of rainfed flooded (lowland) rice. Part of the reduction in grain yield due to the loss of nitrogen under alternately dry and wet conditions which prevailed in the plots subjected to various stress levels. The improved varieties, IR20, IR22, and IR24, consistently out yielded the traditional varieties Peta, Sigadis, and Intan, at all stress levels up to 33 cb. At most stress levels, however, the grain yields were higher with higher nitrogen levels, and more so with improved varieties than with traditional varieties.

Yield response data from 3 dry season experiments were put together in an attempt to explain the field performance of some improved varieties. The analysis for IR5 and several other varieties shows the potential for developing varieties that could effectively respond to high nitrogen levels even under conditions of poor water supply. The analysis brings out short growth duration, vegetativeness, and high fertilizer efficiency as three criteria for varietal selection against drought. For inadequately irrigated areas, relatively higher yields are associated with climatic factors that contribute to low evaporative demand conditions.

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.

Fifteen communal, or village, irrigation systems in Laguna Province were surveyed in 1969. The organization and operation of these systems is described, together with the farmers' evaluation of their irrigation, and estimates of their rice yields.

Using a surface irrigation hydraulics model, relationships were developed between water requirement efficiency and the system design variables. Acrop production function was utilized to relate crop yield to the water requirement efficiency. Gross returns from the crop, and the costs of water, labor, ditch construction and crop production were considered in the optimization problem. Several system constraints were incorporated into the design process. The generalized geometric programming technique was applied to the optimaldesign of border and basin irrigation systems. The design variables were: the length of the run, inflow rate into the border, time of inflow, number of lengths of run, width of the border, and the number of border widths in the field.

One of the major objectives of the EWUP has been to experiment with various on-farm practices to see how the irrigation management activities of the farmers may be improved. The practices tested were precision land levelling, irrigation system design (long furrows and border irrigation), irrigation scheduling, field drain elimination, marwa improvement techniques, and specific plant and crop practices. The purpose of this report is to present the farmers' evaluation of each of these practices. Fifty-four farmer programs were conducted in a six season time span beginning in summer season 1980 to winter season 1983. The package of practices introduced generally provided an increase in crop yield for the farmers but the farmers have not accepted the total number of practices. Some practices are too expensive and cannot be supported by the existing institutional setting, some are notfield applicable, and others are not seen as appropriate by the farmers to their present situations. While the practices themselves have demonstrated a positive effect on the yields for the farmers, the questions as to the ability of the farmers to adopt the practices as presented by EWUP still remains to be pursued.

Botswana currently depends on imports for 80-90% of its vegetable consumption. The Botswana Government is, however, trying to encourage local production for increased self- sufficiency. Botswana is a semi-arid country and both population and water sources are widely scattered. Often the yield of a water source limits the area that can be irrigated at a particular place. Consequently, vegetable farms are small, usually less than five hectares in size. The scattered population leads to problems with marketing. It is uneconomic for farmers to transport small quantities of produce over long distances to find a market. The Department of Agricultural Research is therefore pursuing the "market garden" approach, with individuals or groups of farmers groups of farmers growing a range of produce to try and satisfy their local market. Production is carefully planned to provide as continuous a supply as possible of the major vegetable crops. Irrigated plots have been established (or are planned) in different climatic areas of the country. These are run as "commercial" market gardens and data on costs of production, yields and returns recorded. Information on crop growth and profitability in different areas and at different times of year is obtained. Sample data are presented and problems experienced with these units are discussed.
