“…The underestimation of this stage is the main reason for the low accuracy of T simulation in the whole growth period. Similar results were also found in greenhouse tomatoes (Gong et al, 2019) and cucumbers (Yan et al, 2018), which may be related to the type of convection in greenhouses (Zheng et al, 2021), and the diffusion of water vapor in the greenhouse is greatly affected by man-made disturbances. When the vent is closed or the opening is small, the aerodynamic resistance is relatively high (Yan et al, 2019).…”

“…Greenhouse agriculture can provide a relatively stable growing environment for crops, which is conducive to crop quality, stable yield and improving water and fertilizer utilization efficiency (Chang et al, 2013;Fu et al, 2022). By 2021, the scale of solar greenhouse in Northeast China reached 30×10 4 hm 2 (Zheng et al, 2021).…”

“…When the models generated were compared to traditional methodologies, such as FAO Penman-Monteith (PM) and Hargreaves (HG) equations, it was found that even with limited data, ANN models predicted ET c better than classic equations, requiring only temperature and humidity sensors. This is because, in certain climatic conditions, PM and HG equations can overestimate or underestimate ET c , as has been evidenced by several authors [224][225][226][227][228][229][230][231][232][233].

This review article conducts an in-depth analysis of the role of next-generation technologies in soilless vegetable production, highlighting their groundbreaking potential to revolutionize yield, efficiency, and sustainability. These technologies, such as AI-driven monitoring systems and precision farming methods, offer unparalleled accuracy in monitoring critical variables such as nutrient concentrations and pH levels. However, the paper also addresses the multifaceted challenges that hinder the widespread adoption of these technologies. The high initial investment costs pose a significant barrier, particularly for small- and medium-scale farmers, thereby risking the creation of a technological divide in the industry. Additionally, the technical complexity of these systems demands specialized expertise, potentially exacerbating knowledge gaps among farmers. Other considerations are scrutinized, including data privacy concerns and potential job displacement due to automation. Regulatory challenges, such as international trade regulations and policy frameworks, are discussed, as they may need revision to accommodate these new technologies. The paper concludes by emphasizing that while these sustainable technologies offer transformative benefits, their potential for broad adoption is constrained by a complex interplay of financial, technical, regulatory, and social factors.

Misconceptions and misunderstandings in agricultural water management: Time for revisiting, reflection and rethinking

Over the past years, several concepts in water management have emerged and were further developed. They included approaches for saving water and improving water use efficiency and productivity, sustainable water management strategies, salinity control, remote sensing applications to estimate crop evapotranspiration (ETc), soil moisture, crop yield and land cover, using models as water management tools and for designing reservoirs and dams. The intention was great, but the application of the concepts did not always match the intention. Examples of misunderstandings and misconceptions include incorrect application of deficit irrigation, using water use efficiency instead of water productivity, misunderstanding the water accounting system elements, misuse of the term sustainability, leaching with every irrigation, using the term upscaling instead of aggregation, incorrect use of long‐term average flow for designing dams and reservoirs, believing that remote sensing data are direct measurements for ETc or soil moisture and believing that well‐calibrated/validated models do not have inaccuracy and uncertainty in their results. This paper highlights these concepts and their misuse and misunderstandings as well as explains the true meaning and application of each concept. The paper also explains why concepts were misunderstood and suggests approaches to improve the understanding and accurate application of the concepts.
