This research offers a comprehensive spatio-temporal analysis of irrigation development in Rajasthan, examining the dynamic shifts in irrigation patterns, sources and their compound annual exponential growth rates (CAEGRs), and assessing the impact of various sources of irrigation on the net sown area (NSA). Currently, almost three-fourths of irrigated areas use groundwater sources. Over the last decade, tubewell irrigation has expanded most rapidly (CAEGR: 2.5%), followed by canal irrigation (2.2%), whereas tank irrigation has sharply declined (−2.6%). Furthermore, tubewell irrigation utilization significantly impacts the NSA, especially during the Rabi season in western Rajasthan. However, this increase in groundwater irrigation has an environmental cost in terms of a significant decline in the groundwater level, particularly in districts with relatively high levels of tube-well irrigation. Business, as usual, is not sustainable, as depleting groundwater resources will adversely affect food security in the region. The Rajasthan experience emphasizes exploring the balance between short-term agricultural gains and the protection of critical ecosystems. It also offers vital lessons for dry and semiarid regions around the world that are facing similar challenges.\u0000 </div>","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"75 1","pages":"228-249"},"PeriodicalIF":1.7,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146162700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study undertook a field experiment to examine drip irrigation of maize utilizing lysimeters. The impacts of four distinct nitrogen fertilization treatments, with application rates of 105 (CK), 153 (T1), 204 (T2) and 255 kg ha−1 (T3), on crop growth, development and the efficiency of water and fertilizer utilization were investigated separately. During the experimental period (2021–2022), the yield reached its maximum under the T2 treatment, which were 20% and 32% greater than that of the CK treatment. The water use efficiency (WUE) increased with increasing fertilizer application. Conversely, the partial factor productivity of nitrogen (PFPN) decreased with increasing fertilizer application. Using the calibrated HYDRUS-2D model, we analysed the impacts of irrigation volume and water–nitrogen interactions on water and fertilizer utilization. The simulations revealed an irrigation quota of 1855 m3 ha−1; the maximum root nitrogen uptake was 196 kg ha−1, whereas the nitrogen leaching loss from deep soil was only 12 kg ha−1.

The model innovatively incorporates channel water transmission time parameters to precisely control irrigation sequences and adopts a ‘rotation irrigation between groups—continuous irrigation within groups’ operational mode (based on an improved 0–1 model framework). Setting the optimization goal of synchronized water distribution completion among rotation groups enhances management efficiency. In the empirical study of the Bojili Irrigation District, the model optimized the lateral channel system by dividing it into two rotation groups, achieving the following: (i) The time difference in water distribution completion among channels within each group was significantly reduced (achieving synchronized completion); (ii) a substantial decrease in the flow adjustment frequency of branch channels.
