“…The economic benefits of SDI systems should be evaluated based on specific circumstances and considerations. SDI is recognized for its water-saving effects; however, it may not deliver superior economic benefits when compared to other conventional irrigation methods [78]. As revealed by keyword mapping, relatively few studies have assessed the economic benefits of SDI.…”

“…Moreover, SDI systems rely on electricity to drive water pumps and valves, among other devices, which increases running costs. Since subsurface drip irrigation systems are susceptible to damage from plowing equipment, they are more suitable for low-tillage or no-tillage cropping models [78]. Crop rotation may not be suitable for SDI because the fixed burial depth and spacing of drip heads may be inconsistent with crop row spacing and planting depth, thus reducing irrigation efficiency.…”

Analysis of Hotspots in Subsurface Drip Irrigation Research Using CiteSpace

To investigate the research hotspots and development trends of subsurface drip irrigation (SDI) over the past 20 years, this study analyzed relevant literature from the Web of Science Core Collection spanning from 2002 to 2022. The data were visualized using CiteSpace, showcasing the publication volume trends, countries, keywords, cited references, authors, and affiliated institutions. Based on 1079 articles, the annual publication volume showed an overall upward trend. The United States had the most extensive research coverage and highest publication volume, whereas China had the fastest growing publication rate in recent years. However, relatively little cooperation occurred among research teams and institutions. Over time, research topics became increasingly diverse, with water conservation and yield increases being the primary research objectives. In addition to improving irrigation and fertilizer use efficiency, SDI has also been applied in research on the safe utilization of unconventional water resources (wastewater and salt water) and the optimization of soil conditions. Among these, aerated irrigation technology—aimed at improving root growth in the rhizosphere—may become a new branch of SDI research. Currently, the main research focus in the field of SDI is the diffusion and distribution of water in the crop root zone, for which Hydrus model simulation is a particularly important method.

“…For this reason, the pressure on irrigated agriculture for efficient water use is increasing year on year. This issue is a major challenge for developing countries with large populations (Yadaw et al, 2022).…”

“…Thus, pressurized irrigation has rapidly expanded, reaching approximately 10.7 Mha in the last decade—48% of Mediterranean irrigated lands (Sanchis‐Ibor et al, 2021). For instance, drip irrigation provided water and electricity savings in the ranges of 30–54 and 26–47%, respectively, compared with surface irrigation methods (Çetin & Bilgel, 2002; Yadaw et al, 2022). The economic viability of an irrigation project depends on many factors, such as the cost of the total irrigation equipment installation, operation and maintenance, water savings, energy savings and revenue earned from crop yield (Yadaw et al, 2022).…”

In this study, two different irrigation schemes in Turkey were evaluated. One is Devegeçidi irrigation, which was put into operation in 1972. The command area is 5800 ha, and farmers used surface irrigation. Ergani irrigation, a modern irrigation scheme using drip and/or sprinkler irrigation systems with an irrigation area of 1866 ha, was put into operation in 2021. The average total water use (TWU), irrigation efficiency (IE), water economic productivity (WEP) and net income (NI) were 11,728 m3 ha−1, 45%, $0.21 m−3 and $2354 ha−1 in the Devegecidi irrigation, respectively, and all the same criteria results were 6189 m3 ha−1, 81%, $0.78 m−3 and $4789 ha−1 in the Ergani irrigation, respectively. In addition, irrigation water productivities (IWPs) in wheat, cotton and corn for the Devegeçidi irrigation were 0.78, 0.47 and 1.21 kg m−3, while those values were 0.89, 0.89 and 2.26 kg m−3 in the Ergani irrigation scheme, respectively. The study results show that the modernization of irrigation systems is significantly important in saving irrigation water and increasing the income of farmers and water productivity. These indicators can guide decision makers in the modernization of irrigation systems.
