Abstract
The objective of this investigation was to help new reclaimed landowners and extension specialists to select the appropriate method for irrigation, while minimizing irrigation problems and expenses.
Systems under investigation included: (I) common drip
irrigation system, (2) drip irrigation system with solar-powered
•
pump,
(3) center-pivot sprinkler system, and (4) traditional intensive
irrigation.
Drip-irrigation systems were examined to identify their suitability for powenng with non-conventional source (solar photovoltaic power). Results showed that solar energy, as a power source for water pumping in drip irrigation, is applicable under Egyptian conditions (solar-electric generation efficiency was 8-9%) with the disadvantage of high cost, which hampers widespread in the Nile Delta and Valley, but it stands better chances in the remote areas, where the common energy-sources are not available. Two different solar pumps performance were also given. Measured parameters included resulting moisture distributions in soil and their suitability to shallow or deep-rooted crops.
This evaluation was conducted to establish a selection methodology system to help new reclaimed landowners and extension specialists to select the appropriate method for irrigating their lands, minimizing their irrigation process problems and expenses. The system of selection depended on farm resources (soil, water, crop and labor). Consultations and literatures validated results. Each irrigation method was given a rank number under each individual farming
parameter, the highest summation indicates the most suitable irrigation method for the set conditions.
Five cases were taken for validation (Inshas, Beni-Salama,
Shalakan, Nubaria, and site for proposed testing station at Sohag. Results showed that drip irrigation system is best in saving energy and water in the new by reclaimed-lands, but it was the 2"d choice for old lands in Delta area, where flood system is the 1" choice for these areas.
