Maize is extensively cultivated in northwestern Liaoning, China, where is semi-arid area. It has been a challenge to improve the water use efficiency and income of maize planting in this area. This study conducted field experiments on the maize-<em>Cyperus esculentus</em> intercropping system using drip irrigation over three years in Jianping County of northwestern Liaoning. Yield, water use efficiency (WUE), land equivalent ratio (LER), interspecific competitive ability and net return were measured to compare the advantages of maize-<em>Cyperus esculentus</em> intercropping system with monocropping. Three treatments of irrigation regimes, rain-fed(T1), heavy control (T2), light control (T3), were applied to explore the optimal irrigation regime under the intercropping system. In 2020, the optimal yield of maize in the maize-<em>Cyperus esculentus</em> intercropping system was 7.1 % higher than that in the monocropping system. In 2021, the optimal yield of <em>Cyperus esculentus</em> in the intercropping system was 29.9 % less than that in the monocropping system. The WUE of intercropping system was 12.7 %-49.8 % higher than that of maize monocropping system. LER of three irrigation treatments under maize-<em>Cyperus esculentus</em> intercropping system ranged from 1.78 to 2.42. Interspecific competitive ability of three irrigation treatments under maize-<em>Cyperus esculentus</em> intercropping system was all greater than 0, demonstrating that maize had a higher competitive capability for light, water, and nutrients compared to <em>Cyperus esculentus</em>. The net income of the intercropping system in 2020 is 56,398.5 CNY·hm⁻², 182 % higher than the net income of maize monocropping (19,980 CNY·hm⁻²). The net income of the intercropping system in 2021 was 55,738.5 CNY·hm⁻², 14.5 % higher than the net income of <em>Cyperus esculentus</em> monocropping (48,687 CNY·hm⁻²). T3 water treatment showed the highest yield and net return. The Maize-Cyperus esculentus intercropping system could improve maize yield, improve water use efficiency and increase farmers' income, comparing with monocropping and other intercropping systems. The light control (T3) in the maize-Cyperus esculentus intercropping system is recommended for promotion in northwestern Liaoning.</div></div>","PeriodicalId":7634,"journal":{"name":"Agricultural Water Management","volume":"316 ","pages":"Article 109558"},"PeriodicalIF":5.9,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144124165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These blooms have become more severe, with record events occurring in 2011 and 2015, and have compromised public safety, leading to do-not-drink advisories and negatively impacting the economy of the Western Lake Erie basin. To determine the potential benefits of avoiding nutrient application during high rainfall events compared to dry periods, we analyzed scenarios using three Soil and Water Assessment Tool (SWAT) hydrological models developed for the Maumee River Watershed. These SWAT models were developed by three different institutes and calibrated for flow and nutrient loadings at the watershed outlet. The scenarios varied the timing of nutrient (fertilizer as well as manure) applications at the hydrological response unit (HRU; smallest unit of a model) level based on the risk of rainfall events and included a (1) worst-condition scenario, in which nutrients were applied just before rain events having a high-risk of runoff and a (2) best-condition scenario, in which nutrients were applied during periods carrying a low-risk of runoff. The results demonstrate that applying nutrients during low-risk rainfall events reduced nitrate runoff by 10.9 %, total phosphorus by 1.2 %, and dissolved reactive phosphorus by 3.8 % during the spring season compared to high-risk rainfall events. While, the nitrate, total phosphorus and dissolved reactive phosphorus reductions were 6 % 0.7 % and 2.6 %, respectively on the annual scale. Additionally, nutrient application during high-risk rainfall events led to a reduction in crop yields, with soybean yields decreasing by 4.4 %, corn and rye by 3 %, and winter wheat by up to 5.5 %. These findings underscore the importance of optimizing nutrient application timing to minimize nutrient runoff and enhance crop productivity, contributing to improved water quality in the Great Lakes region.</div></div>","PeriodicalId":7634,"journal":{"name":"Agricultural Water Management","volume":"316 ","pages":"Article 109555"},"PeriodicalIF":5.9,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144124164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we extracted the current rice cropping structure in the Zishui River Basin (ZRB), Hunan Province, leveraging high-resolution Remote Sensing (RS) data. A planting suitability evaluation system for double cropping rice was developed by integrating climatic, soil, and site conditions through an Analytic Hierarchy Process (AHP) and GIS overlay. Based on these inputs, alternative rice cropping scenarios were simulated using the Soil and Water Assessment Tool (SWAT) to evaluate changes in hydrology and yield. The current rice planting scenario (S0) included 27.4 % single and 72.6 % double cropping areas, while 81.5 % of paddy fields were suitable for double cropping. The SWAT model, parameterized with RS-derived structures, achieved excellent streamflow simulation, with a Nash–Sutcliffe efficiency (<em>NSE</em>) of 0.86 and 0.88 during calibration and validation periods, and percent bias (<em>PBIAS</em>) of 4.5 % and 3.1 %, respectively. Simulation results indicated that the optimized rice planting structure (S3) enhanced rice yield with minimal hydrological impacts. Compared to S0, S3 increased irrigation, evapotranspiration, percolation, and rice yield by 4.8 %, 1.4 %, 5.5 %, and 4.0 %, respectively, while full double cropping scenario (S2) achieved an 11.0 % yield increase but raised irrigation demand by 11.2 %.

To support border irrigation management, we previously developed a low-cost sensor for surface irrigation management, which remotely informs the farmer of water arrival downstream of his field and therefore of the moment to stop irrigation. The objectives of this article were: (i) to determine the optimal position of this sensor lengthwise in the field throughout the season, and (ii) to compare the influence of management scenarios (current farmer’s practices, sensor-based and time-based cutoff) on irrigation performance. To this end, an integrated agro-hydraulic model was developed to simulate surface water flow dynamics throughout the season including variations in infiltration and roughness. The model was run using monitoring data from the border irrigation of a hay field during a whole season in Southern France. The results showed that the optimal sensor position can change significantly over the course of the season, depending on inflow rates, initial soil moisture and Manning’s roughness. Sensor-based irrigation control was found to be more efficient than current farming practices, with an estimated water-saving potential of 33%, and more effective than an optimised fixed cutoff time in limiting water losses induced by variability or uncertainty in the initial conditions. For some irrigation events, water savings could reach 50%.

However, despite the recognized potential of satellite remote sensing, Change Detection (CD) techniques have not been widely applied for SM monitoring within more challenging hillside grapevine vineyard environments. To address this gap, this study developed and validated two CD methods for retrieving SM at 20 m resolution using Google Earth Engine. The first method (CD_S2) used S2 optical bands (Red, NIR, SWIR), while the second (CD_S1S2) combined S1’s C-band radar (VV polarization) with S2 optical data. The methods were tested in two hillside vineyards (northern/southern Italy) and validated using independent reference data from flat bushlands (TxSON, Texas). Comparisons with in-situ measurements showed both methods effectively captured SM dynamics. However, combining S1 and S2 data (CD_S1S2) provided significantly more accurate estimates than using S2 alone (CD_S2), achieving higher R² (0.23–0.41 vs. 0.16–0.21) and lower RMSE (3.6–5.7 % vs. 3.8–7.1 % [m³/m³]). This improvement is attributed to S1's ability to penetrate vegetation and operate under various atmospheric conditions.
