“…The results indicated cyclic treatment improved crop yield by 12% as compared with mixing treatment. Oron et al (1999) investigated soil moisture and salinity distribution under subsurface drip irrigation (SDI) and conventional drip irrigation (DI) with saline water in a pear orchard. The results indicated that moisture and salinity distribution under SDI was better adjusted to the root pattern in the soil, in comparison with DI.…”

Use of saline water for irrigation is a strategy to mitigate water shortage. The objective of this study was to investigate the impact of the cyclic and constant use of saline and non-saline water on drip irrigated maize yield and irrigation water use efficiency (IWUE). Nine field treatments were laid out based on alternative irrigation management of non-saline and saline water combinations. The treatments were: two salinity levels of 3.5 and 5.7 dS/m and freshwater (0.4 dS/m) application in every one, three and five saline water application (1:1, 3:1 and 5:1, respectively). Results showed that the 1:1 combination management was the best in terms of crop yield and IWUE. In this treatment, salt concentration at the end of growing season was not significantly changed compared to its initial condition. If off-season precipitation or leaching was available, the 3:1 and 5:1 treatments were appropriated. Highest and lowest values of IWUE were 15.3 and 8.7 kg/m3 for the 1:1 management using water salinity of 3.5 dS/m and the treatment of constant irrigation with water salinity of 5.7 dS/m, respectively. Under low off-season precipitations, artificial leaching is essential for land sustainability in most treatments.

“…Subsurface drip irrigation (SDI) has been developed to improve salinity management and water use efficiency. According to Phene et al (1991) and Oron et al (1998), SDI decreases the accumulation of salts at the root zone level of plants, producing an improved yield and fruit quality. This has been observed in tomato (Ayars et al, 2001;Hanson et al, 2004), onion (Enciso et al, 2007), cotton (Detar, 2007), bean (Gençoglan et al, 2006), potato (Patel and Rajput, 2008) and corn (Payero et al, 2008).…”

A field experiment on the effects of drip irrigation (DI) and subsurface drip irrigation (SDI) with saline water (6.57 dS m -1 ) on three tomato cultivars (Lycopersicon esculentum Mill., cvs. Río Tinto, Río Grande and Nemador) was carried out with the purpose to quantify physiological responses. The aim was to improve irrigation water management under saline conditions of Tunisia. The trial was established in a siltclayey soil with three regimes of irrigation: 100 %, 85 % and 70 % of crop water requirement. Results evidenced a significant difference between the two irrigation systems for the three cultivars. Growth parameters such as leaf area, chlorophyll content and mineral composition of leaves, petioles, stems and roots were affected significantly by the different treatments, particularly for Río Tinto and Nemador, being Río Grande the more adapted. The fruit was the organ less affected. Strong accumulation of Na + and Cl -accompanied a reduction in Ca 2+ , K + , Mg 2+ and P content in the case of DI. The distribution of these last necessary elements for plants nutrition under a strong accumulation of Na + and Cl -depends on the cultivar and changes from one organ to another. SDI can be included as an effective option for tomato production in Tunisia.

“…This agrees with other investigators (Aragüés et al, 2014;Bryla et al, 2005), where the formers reported that the two drip profiles produced more yield and bigger peaches than furrow and micro sprinkled systems, but that no differences between ground drip (GD) and subsurface drip (SDI) were found. Correspondingly, some studies reported an increase of pears yield due to the GD system than the SDI, (Oron et al, 2002), and others reported a contrary result that they found that SDI produces more yield than GD (Oron et al, 1999). The main factor that led to this contradiction was water salinity, as SDI gave better results when used with saline water (Oron et al, 1999), while GD gave better results when using fresh water (Oron et al, 2002).…”

SUMMARYA 2-year study was conducted to determine the effects of different drip irrigation profiles on the yield quantity and quality of mature peach trees [Prunus persica L.]. The irrigation profiles were the combination of emitter location (ground drip or subsurface buried @15cm), emission rate (conventional 4.0 L h -1 or low-flow 0.5 L h -1 ), and water deficiency level (60%, 80%, 100% of ET). The results showed that yield and water use efficiency (WUE) were not affected by the irrigation profiles, while there were some reduction in the yield and improvement in WUE due to water 60% ET deficiency application. On the other hand, some of the fruit quality measures (Total sugars, and maturity index) were affected by the irrigation profile as the low-flow profiles yielded sweeter and more matured fruits. Moreover, the study involved water and salt measurements under each irrigation profile, the conventional drip rate showed more-efficient salt flushing, while the low-flow profiles showed wider lateral movement of water. The best overall treatment under average conditions was the low-flow ground drip with 80% of ET.
