Abstract
In the past 10 years, a great deal effort has been directed
for improving on farm irrigation in Egypt. In order to meet
greater demand for agricultural products due to population
pressure, the Egyptian Government has looked for increasing crop
production in both the vertical and horizontal directions
In order to increase production in cultivated areas of Nile
valley lands, water resources Dust be used more carefully to have
water available for areas currently not utilized. Cnfortunately,
the type o[ irrigation currently used at the farm level is not well
adapted to mechanization due to the large number of bonds and
channels that exist on each feddan. Likewise, improved on-farm
water management plays a role in the vertical direction. In this
respect, precision land levelling may improve uniformity
distribution of irrigation and increase yield per unit of water and
area. On old lands, the predominant method of water application is
basin irrigation. This method is used on well levelled or nearly
levelled lands.
