This study provides insights into the influences of different irrigation water applications on soil water status and its potential effects on grape yields, water use efficiency (WUE) and the cost of irrigation to help improve irrigation practices in the region and other similar Mediterranean regions. The field experiment compared three levels of irrigation water applied: current irrigation of the vineyard (T₀) and two deficit irrigation treatments with reductions to 75% (T₁) and 50% of the irrigated water (T₂). The measurements included volumetric soil water content, shallow groundwater table, canopy cover and grape yield at harvest during the entire growing season (October 2017 to April 2018). We found a potential reduction of 25% or 50% in the current irrigation system while maintaining the grape yield, increasing the WUE and reducing the cost of irrigation. Consideration of the water stored in the soil by the accumulation of rainfall in the winter season and the potential for capillary rise of shallow groundwaters is crucial for adjusting irrigation to vine water requirements.</p>","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"74 1","pages":"316-331"},"PeriodicalIF":1.6,"publicationDate":"2024-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ird.2980","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a randomized split block design, no tillage (NT) with alternate wetting and drying (AWD) and a furrow-irrigated narrow bed (NB) emerged as being consistently competitive, showing potential for sustainable rice cultivation. Key findings indicate that AWD significantly enhances water productivity (11–35%) and increases yield (2–10%) compared to conventional practices. Drip-irrigated wide beds (WBs) conserve substantial amounts of water (73%) but may compromise rice yield (4–47%). This study provides valuable insights into the dynamic outcomes and distinct performance trends of different rice varieties. The results suggest a potential maximum yield increase of 2–22% through optimized practices, and replacing rice may increase yield by 25–231%. Conversely, the selection of improper irrigation schedules and sowing methods for the given soil and crop conditions may lead to a yield reduction of up to 47% in high-yielding rice varieties. These findings may help to establish a foundation for further research investigating informed decision making for sowing and irrigation methods. The potential scalability of the identified technologies and further in-depth simulation strategies across diverse agroecological zones in Pakistan holds promise for widespread adoption, enhancing the sustainability of rice farming in the region.</p>","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"74 1","pages":"332-341"},"PeriodicalIF":1.6,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141120785","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}

The general management performance index revealed that the most successful WUOs in the Konya closed basin were WUAs. Therefore, proposals have been put forward to begin institutionalization processes in other institutions to attain the successful institutionalization in WUAs.

This phenomenon prompts the question: has there been a corresponding impact on potential evaporation? To explore changes in potential evaporation resulting from irrigation advances, we conducted a comprehensive analysis spanning the years 1978–2017 in Xinjiang. Our investigation focused on a pairwise examination of agricultural stations with substantial irrigation effects, enveloped by a substantial proportion of cultivated land, and reference stations with negligible irrigation effects, surrounded by a comparatively smaller proportion of cultivated land. The findings unveiled a noteworthy reduction in potential evaporation at agricultural stations during the period 1978–1997. However, a contrasting trend emerged in the subsequent period of 1998–2017, wherein there was a significant increase in potential evaporation. In contrast, reference stations did not exhibit statistically significant reversals in potential evaporation. The observed changes in potential evaporation at agricultural stations were primarily attributed to shifts in aerodynamic components. These changes were closely associated with the reversed changes in irrigation intensity, a consequence of the widespread adoption of water-saving irrigation practices since 1998.</p>","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 5","pages":"1913-1923"},"PeriodicalIF":1.6,"publicationDate":"2024-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140986794","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}
