Special Issue Information

Dear Colleagues,

The growing global demand for food, coupled with increasing water scarcity and the impacts of climate change, places unprecedented pressure on irrigated agriculture. Traditional irrigation methods are often insufficient to meet these challenges, necessitating a paradigm shift towards more intelligent, efficient, and sustainable water management systems. True advancement lies not only in developing new technologies but also in their integration with deep ecological and physiological understanding.

This Special Issue, "Advances in Crop Irrigation System and Management", aims to showcase research at the forefront of this transformation. We invite contributions that connect cutting-edge engineering and data science with fundamental plant biology and soil science. We are particularly interested in studies that explore precision irrigation through AI and IoT, innovative strategies like controlled deficit irrigation, the safe use of non-conventional water resources, and the physiological and molecular responses of plants to different irrigation regimes. Our goal is to assemble a collection of high-impact works that provide actionable solutions and chart a course toward a future of resilient and resource-efficient agriculture.

The Special Issue should also include research involving the use of Artificial Intelligence as an essential tool for promoting sustainability in the rural production sector, such as the use of machine learning algorithms that can predict optimal water and nutrient intake and monitor irrigation systems, enabling the greater efficiency/optimization of water resource use. It is important to highlight the applicability of Artificial Intelligence in the use of sensors to collect field data of various types, from crop water needs to pest attacks, assisting producers in decision-making.

In arid and semiarid regions of the world, irregular and low-intensity rainfall prevails throughout the year, in addition to high evapotranspiration demands, which directly impact water bodies with high salt content. The use of this water in irrigated agriculture results in saline and water stress for crops. Therefore, to enable irrigated agriculture to fulfill its important role as a food and fiber supplier to the global population, this Special Issue hopes to contribute to the dissemination of ongoing research aimed at developing advanced technologies to mitigate saline and water stress in irrigated crop cultivation.

Finally, it should be noted that in addition to scientific articles, this Special Issue welcomes the submissions of literature reviews, considering these to be of paramount importance for supporting the development of future research, while also providing significant benefits to authors in terms of the potential for increased citations of their scientific work.

This study aimed to evaluate the effect of selenium concentrations in mitigating salt stress on the physiology, growth, and yield of okra plants irrigated with brackish water. Treatments consisted of four irrigation water salinity levels (ECw: 0.4, 1.3, 2.2, and 3.1 dS m−1) combined with four selenium concentrations (0, 5, 10, and 15 mg L−1), arranged in a randomized block design in a 4 × 4 factorial scheme, with three replicates and one plant per plot. Increasing irrigation water salinity from 0.4 dS m−1 reduced relative water content, gas exchange, initial chlorophyll a fluorescence, plant growth, and production of okra, while increasing the percentage of electrolyte leakage. Irrigation Water salinity levels above 0.4 dS m−1 impaired plant water status, gas exchange, growth, chlorophyll a fluorescence, yield, and water-use efficiency, while increasing electrolyte leakage. Salinity above 1.0 dS m−1 also inhibited photosynthetic pigment synthesis. Selenium did not mitigate salinity-induced reductions in chlorophyll and carotenoids. However, foliar Se at 8.6–15 mg L−1 enhanced gas exchange, chlorophyll a fluorescence, growth, and fruit yield under salinity up to 3.1 dS m−1. These results support Se induced attenuation of salinity stress, warranting further mechanistic studies. Full article
