Special Issue Information

Dear Colleagues,

Following the tremendous success of the first edition of the “Irrigation and Water Management Strategies for Horticultural Systems” Special Issue, a second edition is being launched.

Water is an essential element for plant growth and one of the main limited resources for agricultural development, especially in arid and semi-arid regions. During the past few decades, water use and water management have received more and more attention, considering the increase in water demand and the limited water supply, especially for the agricultural sector, which is the largest water consumer. Irrigation and water management are also important for salt regulation in saline soil area. Moreover, alternative irrigation resources and unconventional water sources, such as brackish water and reclaimed water irrigation, are also receiving increasing attention.

This Special Issue provides a platform for the discussion of irrigation and the water utilization of plants, including how a well-planned irrigation schedule or management promotes plant growth, leaf photosynthetic capacity, grain and forage yield, quality, and water use efficiency, as well as production benefits.

This Special Issue invites original research, modelling approaches and methods, and reviews on water management strategies for horticultural systems. Topics include, but are not limited to, the following: (1) examinations of how plants efficiently perceive and take up water in the soil; (2) diagnosis of water deficiencies; (3) the effects of different water management practices on plant growth, dry matter accumulation and translocation, nutrient uptake, forage quality, yield, and water and fertilizer use efficiencies; (4) optimized irrigation practices, cropping systems, and agronomic strategies for improving water use efficiency; (5) the plant response to water and salt stress; (6) unconventional water resource utilization in horticultural systems; (7) and research on secondary salinization and its prevention and control in facility horticultural soil.

The increasing frequency and intensity of droughts, a direct consequence of climate change, represent one of the main threats to agriculture, especially for crops with a high water demand such as the processing tomato. The objective of this study is to evaluate the potential of the IrriDesK digital twin (DT) as a tool for automated irrigation management and the implementation of regulated deficit irrigation (RDI) strategies tailored to the crop’s water status and phenological stage. The trial was conducted in an experimental plot over two consecutive growing seasons (2023–2024), comparing three irrigation treatments: full irrigation based on lysimeter measurements (T1) and two RDI strategies programmed through IrriDesK (T2 and T3). The results showed water consumption reductions of 30–45% in treatments T2 and T3 compared to treatment T1, with applied volumes of 277–400 mm versus approximately 570 mm in treatment T1, thus remaining within the sustainability threshold (<500 mm, equivalent to 5000 m3 ha−1). This threshold corresponds to the maximum seasonal allocation typically available for processing tomato under drought conditions in the region and was used to configure the DT’s seasonal irrigation plan. The monitoring of leaf water potential (Ψleaf) and the normalized difference vegetation index (NDVI) confirmed the DT’s ability to dynamically adjust irrigation and maintain an adequate water status during critical crop phases. In terms of productivity, treatment T1 achieved the highest yields (≈135 t ha−1), while RDI strategies reduced production to 90–108 t ha−1, but improved fruit quality, with increases in total soluble solids content of up to 10–15% (°Brix). These results demonstrate that IrriDesK is an effective tool for the optimization of water use while maintaining crop profitability and enhancing the resilience of processing tomatoes to drought scenarios.
