✦ Synopsis
The scarcity of fresh water in arid regions makes saline water a valuable alternative water source for irrigation. Saline water has an agricultural potential but it is necessary to develop special management procedures to obtain maximum yield and high product quality.
Field experiments, which were carried out in a pear orchard, demonstrate that the choice of irrigation method is very important for saline water irrigation. It was shown that by using saline water through subsurface drip irrigation (SDI) reasonable yields can be obtained. Moisture distribution under SDI is better adjusted to the root pattern in order to counteract osmotic e!ects of the soil salinity in comparison to conventional drip irrigation. Saline water use, particularly through SDI, tends to increase sugar content and acidity of the fruits simultaneously, along with decreasing fouling phases.

## ABSTRACT An experiment was conducted to evaluate evapotranspiration (ET~c~), water use efficiency (WUE) and yield of wheat as affected by quantity and salinity of irrigation water. Treatments consisted of 16 combinations of irrigation water levels, viz. 0.5, 0.75, 1.00 and 1.25 times the water r
The time schedule of micro-irrigation for a given irrigation interval can be expressed by an irrigation scheduling parameter which is de"ned as the ratio of the amount required and the amount applied. Di!erent values of the scheduling parameter can provide over-irrigation as well as de"cit irrigatio

Surface irrigation, including every-other and ordinary furrow irrigation is used more than pressurized irrigation due to the low cost and energy requirements. However, more precise selection of design parameters for efficient design of surface irrigation is required for higher irrigation efficiency
