Because this plant is a summer crop, irrigation is critical to its production, and an absence of moisture is a significant constraint on its development. This study aimed to investigate the impacts of hydrophilic polymer (HP) and fulvic acid (Fu-A) as amendatory materials on yield, yield component, and photosynthetic parameters of corn plants under the deficit irrigation (DI) situation. The treatments were performed by mixing two water provision groups, including complete irrigation (CI) and DI, two soil improvements, including the application of without HP or with HP, and two foliar amendments, including spraying without Fu-A or with Fu-A, with four replications. According to the results, under DI and CI situations, the co-treatment of two amendatory materials, Fu-A and HP, enhanced corn yield significantly. These enhancements were higher than enhancements attained by using them alone. Besides, the moisture and leaf proline available for the plant during DI circumstances were increased by utilizing both amendatory materials. Under DI treatment, using Fu-A and HP amendatory materials together may thus be more significant and beneficial for increasing production and boosting photosynthetic mechanisms.","PeriodicalId":23573,"journal":{"name":"Water Science & Technology: Water Supply","volume":"12 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135042848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study set out to investigate the effect of different levels of water and nitrogen on yield, soil nitrogen, as well as water productivity indices of winter wheat and barley. The experimental treatments were of three nitrogen levels: no nitrogen fertilizer (N0), 50 kg N ha−1 (N1), and 150 kg N ha−1 (N2), as well as two irrigation levels containing deficit irrigation (I1) and full irrigation (I2). Each treatment was repeated three times. Wheat yield for I2 was 5,640 kg ha−1 and for I1 was 3,720 kg ha−1. The yield for barley was 5,620 and 3,850 kg ha−1 for I1 and I2, respectively. The irrigation water productivity (WPi) was increased by 55% for wheat and 83% for barley under deficit irrigation level. We recommend the use of 50 kg ha−1 (instead of 150 kg ha−1), knowing that it reduces the yield and water productivity for wheat by 11.7 and 10.9%, and by 14.5 and 12.6% for barley, respectively. In contrast, the soil nitrogen residual for wheat and barley was reduced by 56.6 and 66.1%, respectively, thus greatly reducing the risk of contamination of groundwater resources.","PeriodicalId":23573,"journal":{"name":"Water Science & Technology: Water Supply","volume":"102 51","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135137998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the Sanhekou Reservoir is still under construction, the periodic wetting-drying events may result in the release of inorganic phosphorus from the soil into the water once it is completed. Therefore, this study aimed to investigate the background soil values and estimate the phosphorus release fluxes of the Puhe River, Wenshuihe River, and Jiaoxihe River of the reservoir. We would like to provide a theoretical basis for the subsequent management and ecological protection of the reservoir based on this study. The Chang–Jackson chemical continuous extraction method was used to determine the forms of inorganic phosphorus in the soil, and fluorescence data were obtained by excitation–emission matrix combined with parallel factor (EEM-PARAFAC). The results showed that there were four types of phosphorus in the soil of the reservoir, including calcium-bound phosphate, aluminium-bound phosphate, iron-bound phosphate, and occluded phosphate. The total quantities of these phosphorus types were measured to be 6.71 × 104, 1.14 × 104, 0.91 × 104, and 0.49 × 104t, respectively. Additionally, it was observed that there was 2.12 × 104 t of bioavailable phosphorus present in the soil.","PeriodicalId":23573,"journal":{"name":"Water Science & Technology: Water Supply","volume":" 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135242248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings of the study revealed that only Huaibei achieved efficiency according to the DEA model, while the other cities in the northern Anhui region did not exhibit the same level of efficiency. The overall water resource utilization efficiency in the region was low, with significant variations among the cities (p ≤ 0.05; ANOVA test). The order of water resource utilization efficiency from high to low was Huaibei, Huainan, Bengbu, Bozhou, Suzhou, and Fuyang. An analysis of investment redundancy revealed that a large number of employees and an unreasonable water use structure were key factors that restricted the efficiency of water resource utilization in the region. The overall TFP index of water resource utilization efficiency in the region showed an upward trend, with a value of 1.02.

This study evaluated the capability of the AquaCrop model in simulating wheat yields, crop water use, and water footprints in the Middle-Manyame sub-Catchment, Zimbabwe. The model was calibrated and validated using experimental data collected from field experiments. Simulation experiments were conducted to assess the impact of early and late planting, drip and sprinkler irrigation techniques, and no mulch, organic mulch, and synthetic mulch options on the water footprint (WF). The AquaCrop model accurately simulated soil water content, crop water use, crop biomass, and grain yield. Simulation runs showed that early planting reduced WFblue and WFgreen by 25 and 4%, respectively. The lowest consumptive WF was observed with drip irrigation and synthetic mulching. The greatest decline in WFblue and WFgreen (52 and 11%) was simulated under early planting, using drip irrigation and synthetic mulching. Overall, the study highlights the importance of efficient crop and irrigation management practices to reduce water footprints in agroecosystems.","PeriodicalId":23573,"journal":{"name":"Water Science & Technology: Water Supply","volume":"43 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135432749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional mathematical and statistical methods and Piper trilinear diagrams show that the cations in the groundwater samples of the mine area are mainly K+ + Na+ (92.4%), while the anions in the Cenozoic and Carboniferous aquifers are mainly Cl−, reaching 57.2 and 55.2%, respectively, and the anions in the Permian aquifer are mainly HCO3- (52.6%). Most of the water chemistry types are Cl-Na, HCO3-Na, and HCO3-Cl-Na. Analysis on the basis of Gibbs plot showed that the aquifer system in the mine area is primarily controlled by the water–rock interaction.

The method uses seven parameters, namely, depth to groundwater table, net recharge, aquifer media, soil media, topography, land use and land cover, and hydraulic conductivity to obtain vulnerability index values. These index values are validated with one or a few elements of water characteristics as pollution indicators. In most of the reported studies, the correlation coefficient between the DRASTIC index and the concentration of individual element(s) was low. The present study uses the water quality index (WQI) to correlate with the DRASTIC index value. In this paper, 11 physical and chemical water characteristics data of 31 well locations within the Faridabad District of Haryana, India are utilized to estimate the WQI. The correlation coefficients for single element concentration with DRASTIC index vary between the range of 0.104 to 0.304. The correlation coefficients for the concentration of NO3- and WQI are found to be 0.104 and 0.533, respectively. Thus, the DRASTIC index demonstrates a stronger correlation with the WQI when compared to single element concentration.","PeriodicalId":23573,"journal":{"name":"Water Science & Technology: Water Supply","volume":"33 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135819478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
