“…The cause of this finding should be further researched. Many researchers reported a quadratic relationship between the grain yield and irrigation volume, which is similar to our results (Singh et al, 2009;Liu et al, 2011Liu et al, , 2013Jiang et al, 2012). Zhang et al (2008), Liu et al (2011) and Liu et al (2013) reported that the relative high yield of winter wheat was not achieved by the full water supply treatment.…”

“…Regarding the effects of the irrigation volume and salinity on grain yield, Jiang et al (2012) reported that wheat yield decreased by 8.1 and 8.9% when water salinity increased from 0.62 to 3.2 dS m −1 , and 0.62 to 6.1 dS m −1 , respectively. In the first growing season, the grain yields were decreased by 3.7 and 4.7% with irrigation volume of 0.8E, 3.5 and 4.5% with the irrigation volume of 1.0E, 3.1 and 6.1% with the irrigation volume of 1.2E, 3.2 and 6.4% with the irrigation volume of 1.4E when the water salinity increased from S1 to S2 and S3, respectively.…”

“…Several researchers have demonstrated the use of saline water in wheat with pot or field experiments (Murtaza et al, 2006;Wang et al, 2007;Ould Ahmed et al, 2007;Chauhan et al, 2008;Singh et al, 2009;Pang et al, 2010;Jiang et al, 2012). Sharma and Rao (1998) reported that the mean yield reduction of wheat grown in a sandy loam soil in India was 4.2,9.7,16.3 and 22.2% at irrigation water salinity of 6, 9, 12 and 18.8 dS m −1 , respectively.…”

Origin and mechanisms of high salinity in Hombolo Dam and groundwater in Dodoma municipality Tanzania, revealed

et al. 2017

The Hombolo dam (HD), in central Tanzania, is a shallow reservoir characterized by high salinity that limits its use for human activities. The origin of the salinity, mechanisms of reaching and concentrating in the dam remain unclear. These were assessed using hydrogeochemical facies, water type evolutions and mapping. The source of HD salinity was identified to be shallow groundwater (SG) and runoff from a seasonal floodplain with NaCl-rich lithological materails, along Little Kinyasungwe River that feeds the dam. The NaCl-rich lithological units, about 5-7 km upstream of the dam, were highly concentrated with NaCl to the extent that the local community was commercially separating table salt from them. The physicochemical parameters from these NaCl-rich lithological materials were well represented in HD and nearby groundwater sources, which suggests active water interactions. Water type evolution and surface hydrology assessments clearly showed that SG in the salty-floodplain was influenced by evaporation (ET) and was periodically carried to the HD. Clearly; HD water had high chemical similarity with the nearby SG. This agrees with previous studies that HD is partly fed by the local aquifer. However, this is the first attempt at mapping its physical origin. The origin of HD salinity was further supported by the spatial distribution of electrical conductivity (EC), where very high EC (up to 21,230 lScm ) was recorded in SG within the NaCl-rich lithological unit while water sources far away from the NaClrich materials had much lower EC values. Thus, the study disagrees with previous conclusions that HD salinity was sorely due to high dam surface ET but is primarily due to geological reasons. Comparisons of HD with a nearby Matumbulu dam (MD), another earthen dam in climatologically similar settings, reveals that MD water was less saline/ mineralised. This further shows that HD high salinity is most likely a geologic phenomenon, but local climatic factors, namely high ET, decreasing rainfall and warming trends are likely to have concentrated the salts further. Although HD is widely/ideally used for grape vine irrigation, it was clearly revealed that its prolonged usage would potentially affect the soil and grape productivity due to high salinity.

No‐tillage with reduced water and nitrogen supply improves water use efficiency of wheat in arid regions

et al. 2020

No‐tillage, plastic mulching, optimal irrigation, nutrient management, and crop rotation are valuable strategies for improving water use efficiency (WUE) in arid regions, but the effect of no‐tillage combined with plastic mulching on WUE has not been tested. In 2016 and 2017, a field experiment was conducted after plastic mulched maize (Zea mays L.) in northwestern China to assess how tillage, irrigation, and nitrogen levels affect soil evaporation (E), evapotranspiration (ET), grain yield (GY), and WUE of wheat (Triticum aestivum L.). This study evaluated all combinations of two tillage practices (NT, no‐tillage with previous plastic mulching; CT, conventional tillage), two irrigation levels (high: local conventional irrigation amount, 240 mm; and low: local conventional irrigation amount reduced by 20%, 192 mm), and three nitrogen levels (high: local conventional nitrogen amount, 225 kg ha−1; medium: local conventional nitrogen amount reduced by 20%, 180 kg ha−1; and low: local conventional nitrogen amount reduced by 40%, 135 kg ha−1). Across the study years, NT reduced E and E/ET and increased GY and WUE at all irrigation and nitrogen levels compared with CT. No‐tillage with low irrigation and medium nitrogen reduced E, ET, and E/ET by 29%, 4%, and 26%, respectively, and improved GY and WUE by 19% and 24%, respectively, compared with CT with high supplies of irrigation and nitrogen. We concluded that NT into plastic mulched maize with a reduction in irrigation and a moderate level of nitrogen can improve WUE of wheat in arid regions, thereby enhancing the sustainability of cereal production.
