“…The effect of the applied irrigation volumes on WP irrig was significant, with the highest WP irrig in the I1 treatment (6.48 kg m −3 ) and the lowest in the I3 treatment (3.40 kg m −3 ). Then, the WP irrig decreased with increasing irrigation amounts, as found by several authors on maize and other crops (Ali and Talukder, ; Wang et al , ). This may be due to inefficient use of water and inefficient translocation of assimilates to the grain with increasing water supply (Ali and Talukder, ).…”

A field experiment was carried out in southern Italy to investigate the effects of irrigation and salinity on a maize crop and soil properties. The experiment was laid out comparing different irrigation rates (I1, I2, I3—re‐establishing 50, 75 and 100% of the calculated maximum evapotranspiration) and water quality (FW, fresh water and SW, saline water). Grain yield was significantly greater by 60% in 2008 than in 2010. No significant difference was shown for grain yield between the irrigation treatments, whereas water productivity decreased significantly with increasing irrigation rates. Irrigation with saline water did not significantly reduce grain yield compared with fresh water, but it improved grain quality with higher protein content (9.1%) and lower grain moisture percentage (13.3%). Saline water determined a significant increase of saturated soil paste extract Na, ECe, SAR, some exchangeable cations and ESP compared with FW in both years. Furthermore, at the end of the experiment these parameters were lower than those at the end of the first maize crop. Lastly, in the saline treatment, at the end of the trial, the ECe and ESP values were below the critical threshold for soil salinization and/or sodification. Copyright © 2016 John Wiley & Sons, Ltd.

“…The freshwater was tap water from the laboratory irrigation system with a salinity of 0.12 g L −1 and EC of 0.30 dS m −1 . Brackish water with salinity ranging from 2 to 5 g L −1 has been increasingly used for irrigation in many areas of China (Wang et al, 2015). Sodium and chloride are considered the primary ions in the saline water resources of the current coastal area (Li et al, 2016).…”

The coastal regions of eastern China have substantial potential for agricultural production. Freshwater scarcity makes the utilization of plentiful brackish water a vital issue in this area. We aim to assess the effects of cycle irrigation with fresh and brackish water on soil salinity and maize (Zea mays L.). A pot experiment was performed with two typical coastal soils (sandy loam and silt loam) and one local maize cultivar. The maize growing season was divided into three phases (development, mid‐, and later stage). Cycle irrigation was conducted using brackish water (5 g NaCl L−1) during one stage and freshwater for the remaining stages. Cycle irrigation using brackish water at the development stage caused both osmotic and ionic stresses on the maize, leading to significantly‐reduced evapotranspiration (ET), increased stem and leaf Na+/K+ ratio, and stunted growth. The decline of kernel number and 100‐grain weight resulted in severe yield loss. Cycle irrigation with brackish water at the mid‐stage induced less adverse effects on crop growth, while the decrease in kernel number remarkably reduced the yield. Cycle irrigation with brackish water at the later stage minimized the impacts of saline irrigation on soil salinity and maize productivity. Nonetheless, salt leaching by off‐season rainfall and low salinity water and soil salt monitoring should be considered before the next season. Compared to sandy loam soil, silt loam displayed higher soil salinization, and lower maize growth and yield. Additional field research is recommended to facilitate the reliable use of coastal soil and water resources. Core Ideas Cycle irrigation with fresh and brackish water in two coastal soils is studied. Cycle irrigation using brackish water is effective when freshwater is scarce. Brackish water is proposed to be used at maize later reproductive stages. Sandy loam soil is preferable for cycle irrigation compare to silt loam soil.

“…The results of a study in Khuzestan province showed that in dry and normal years, water productivity decreased when water consumption declined (Andarzian et al, 2011). The significant effect of using water amount on water productivity in the North China Plain, which is faced with poor quality water, has also been reported (Wang et al, 2015).…”

Irrigation scheduling plays a key role in increasing crop production and controlling soil salinity in arid and semi‐arid regions. Inappropriate irrigation scheduling is considered an effective factor in low water productivity and soil salinization in central and southern parts of Khuzestan. Therefore, the aim of this research was to improve irrigation scheduling in order to increase water productivity and maintain the water and salt balance in a district in central Khuzestan. AquaCrop was selected as the research model, and the effects of the scenarios on wheat grain yield, water productivity, salt and water content in an effective root zone, and salt content moved upward from the groundwater table by capillary rise were compared with each other. Various scenarios of irrigation scheduling were simulated for a 12‐year period (2003–2014). To collect the required data for calibration and validation of the model, a field experiment was carried out during the wheat growing season (2014–2015). The results of the model evaluation indicated that it was an appropriate one for simulating the water and salt balance in the soil and wheat grain yield under different irrigation scheduling scenarios in experimental conditions. Finally, the recommended irrigation scheduling for wheat was seven times of irrigation with 550 mm water consumption. © 2018 John Wiley & Sons, Ltd.
