“…The least corn yield was obtained with W 1 (9 dS/m) treatment. This result is similar with results obtained by Wan et al (2010) and Mostafazadeh-Fard et al (2009). Mean comparison of corn biomasses (dry yield) indicates that W 3 treatment significantly increased corn dry yield in comparison with W 1 treatment.…”

“…Choudhary et al (2006) investigated effectiveness of cycling method in order to use sodic water for long term irrigating of sunflower in agriculture lands. For dealing with soil salinity and sodicity as consequences of irrigation with saline groundwater or drainage water some results have been published by Mostafazadeh-Fard et al (2009), Heidarpour et al (2009) and Heakal et al (1990 which all of them proved that with increasing leaching fractions, lower soil salinity and higher yield could be achieved. Recently researchers have shown that impact of applying some amendments in combination with leaching methods were reliable for reclamation of sodic soils .…”

“…The reason why pot weight diminished might be due to the possibility that: a) salinity negatively affected substrate ability to retain water, and b) lower irrigation frequency under RW caused worse rehydration for the top part of the substrate. Mostafazadeh-Fard et al (2007) reported that salinity decreases soil structure stability, and Tilt et al (1987) found that plant growth was significantly correlated with the water retention properties of substrates. This behavior observed under RW points to an important limitation of using balances to control irrigation when there are problems in substrate rehydration or/and water retention.…”

The objective of the present study was to investigate the limitations of irrigation with saline reclaimed wastewater (RW) for producing potted weeping fig (Ficus benjamina L.). Furthermore, two different levels of leaching were studied to ascertain whether either reduces the negative effects of RW. Three irrigation treatments were applied: a) well water (control), b) RW (5 dS m -1 ) with a constant leaching fraction of 23% (RWL), and c) RW (5 dS m -1 ) with a constant leaching fraction of 15% and 50% flushing every nine irrigation events (RWF). After five months of exposure to the RW, plant size, leaf area, specific leaf area, plant DW, stem diameter and shoot/root ratio were reduced, but both compactness and the appearance of the plants remained high. RWF reduced leaf area, plant dry weight, stem diameter, leaf lightness, leaf chroma and leaf SPAD compared with the RWL. Water consumption per pot was higher in control (50.58 L), followed by RWL (24.29 L) and RWF (19.6 L). Photosynthesis and stomatal conductance were 50% lower in RWL plants than in the control, while the RWF plants had the lowest rates. RWF caused damages in the photochemical apparatus. This study confirms that: a) weeping fig is a good candidate for being grown with saline RW without compromising its aesthetic value; b) RW may be regarded as a good alternative to the retardants used in this plant; and c) the recommended irrigation would be RWL.Additional key words: irrigation; ornamental plant; pot plant; salinity. Resumen El riego con agua residual depurada salina permite producir ficus (Ficus benjamina L.) en maceta con una pérdida de calidad mínimaEl objetivo del estudio fue investigar las limitaciones del riego con agua residual regenerada salina (RW) en la producción de Ficus benjamina L. en maceta. Se valoró también la efectividad de dos niveles de drenaje para reducir los efectos negativos del RW. Los tratamientos fueron: a) agua no salina (control), b) RW con 5 dS m -1 y un 23% de drenaje (RWL), y c) RW con 5 dS m -1 y un 15% de drenaje, más un 50% de lavado cada 9 riegos (RWF). Después de 5 meses bajo RW el tamaño de la planta, área foliar, área foliar específica, peso seco de la planta, diámetro del tallo y el ratio parte aérea/raíz fueron reducidos, mientras que la compacidad y el aspecto ornamental estuvieron dentro de los patrones comerciales adecuados. RWF produjo una disminución del área foliar, peso seco de la planta, diámetro del tallo, luminosidad y saturación del color de la hoja, y de la clorofila foliar (SPAD) en comparación con RWL. El consumo de agua fue mayor en el control (50,58 L), seguido de RWL (24,29 L) y RWF (19,6 L). La fotosíntesis y la conductancia estomática fueron un 50% menor en las plantas bajo RWL respecto al control, mientras que las plantas bajo RWF presentaron los registros más bajos. RWF produjo daños en el aparato fotoquímico. Este estudio indica que: a)

“…This could be the main factor in the large difference between the EC e of the topsoil and that of the deep soil layer. As reported in many studies (e.g., El-Haddad and Noaman 2001;Mostafazadeh-Fard et al 2007), accurate estimation of the leaching requirement is key to reducing soil desalinization. To calculate this, it is important to take into account the depth of the soil profile (to prevent soluble salt from being deposited in the deeper soil layers), the salinity threshold of the crop (4 dS m −1 for the date palm), and the salinity level of the applied water.…”

As stated by Mostafazadeh-Fard et al (2007), the accurate estimation of the leaching requirement, the application of irrigation water of a suitable salinity, and the use of a well-designed drainage system represent an effective overall approach to managing soil salinization in arid lands.…”

When saline water is used to irrigate crops in arid environments, appropriate irrigation management should be applied to avoid negatively impacting soil characteristics. In this study, the effects of irrigating date palms with saline water (2.24 g l −1 ) on soil physicochemical characteristics such as the electrical conductivity (EC e ), the pH of the saturated soil paste (pH e ), the concentrations of soluble cations (Ca 2+ , Mg 2+ , Na + ), the sodium adsorption ratio (SAR), the saturated soil hydraulic conductivity (K s ), and the volumetric water content of the soil (θ v ) were evaluated in a Tunisian Saharan cropland, the Dergine Oasis, during a 4-year period (2012)(2013)(2014)(2015). The effects of three different irrigation treatments of date palms on soil properties were investigated: low treatment (90% of the net irrigation requirement (NIR) of date palms was applied); medium treatment (100% of NIR was applied), and high treatment (110% of NIR was applied). The results showed that the application of saline water for irrigation inevitably has a negative impact on the physicochemical properties of the soil. Irrigation with saline water was observed to have severe negative impacts on the soil characteristics, especially EC e , Na + , K s , and θ v . However, among the three irrigation treatments applied, statistical analysis (Duncan's multiple range test) indicated that the high treatment significantly (p < 0.05) minimized the degradation of soil characteristics by the saline water; this treatment decreased EC e , Na + , and SAR and increased the water content, θ v , of the studied soil.
