“…These factors likely helped sustain net photosynthesis, leading to an increase in NPP ( Figure 10A ) and ultimately boosting the yield of the cultivar, even in conditions of water scarcity. Recent studies on wheat ( El-Sanatawy and Zedan, 2020 ) and pea ( Soni et al., 2021 ) plants have also demonstrated enhanced productivity in plants treated with SA under water stress.…”

“…It promotes an increase in relative water content ( Carvalho et al., 2020 ), the concentration of organic solutes, and the activity of antioxidant enzymes ( Shemi et al., 2021 ; Jales Filho et al., 2023 ). Silicon also regulates mechanisms that counteract oxidative stress ( Arif et al., 2023 ) and increases the productivity of plants grown under water deficit ( El-Sanatawy and Zedan, 2020 ).…”

IntroductionSalicylic acid has shown promise in alleviating water stress in cultivated plants. However, there is a lack of studies confirming its effectiveness in cowpea plants grown in field conditions. Therefore, this research aimed to evaluate the use of salicylic acid as a water stress mitigator in cowpea cultivars under different irrigation depths in field conditions.MethodsFour cowpea cultivars (BRS Novaera, BRS Tapaihum, BRS Pujante, and BRS Pajeú) were subjected to different treatments: control (W100: 100% replacement of crop evapotranspiration – ETc), W50 (50% of ETc), W50+SA2 (50% of ETc + 276 mg L-1 of SA), and W50+SA4 (50% of ETc + 552 mg L-1 of SA). The treatments were combined in a 4×4 factorial scheme with three replications, arranged in a randomized block design.ResultsWater restriction had a negative impact on the water status, growth, gas exchange, and production of the cultivars while also leading to changes in the antioxidant metabolism and osmolyte concentration. The application of SA enhanced antioxidant activity and the synthesis of osmotic adjusters under stress conditions. The most effective concentration was 276 mg L-1 in stage R2 and 552 mg L-1 in stage V7, respectively. The BRS Pujante cultivar showed increased productivity under water restriction with SA application, while the BRS Tapaihum was the most tolerant among the cultivars studied.DiscussionIn summary, our findings underscore the importance of using SA to mitigate the effects of water restriction on cowpea cultivation. These discoveries are crucial for the sustainability of cowpea production in regions susceptible to drought, which can contribute to food security. We further add that the adoption of new agricultural practices can enhance the resilience and productivity of cowpea as an essential and sustainable food source for vulnerable populations in various parts of the world.

Some food crops such as wheat (El-Sanatawy and Zedan 2020 ; Ma et al 2019 ; Zhang et al 2021 ), maize (Ma et al 2016 ; Salem et al 2021 ) and horticultural flowers such as marigold flower (Yasheshwar et al 2017 ) also had related studies on the application of RDI. With the deepening of the study, the physiological basis of the effects of RDI on plants and the response of plants had become increasingly clear.…”

The deficient agricultural water caused by water shortage is a crucial limiting factor of horticultural production. Among many agricultural water-saving technologies, regulated deficit irrigation (RDI) has been proven to be one of the effective technologies to improve water use efficiency and reduce water waste on the premise of maintaining the quality of agricultural products. RDI was first reported more than 40 years ago, although it has been applied in some areas, little is known about understanding of the implementation method, scope of application and detailed mechanism of RDI, resulting in the failure to achieve the effect that RDI should have. This review refers to the research on RDI in different crops published in recent years, summarizes the definition, equipment condition, function, theory illumination, plant response and application in different crops of RDI, and looks forward to its prospect. We expect that this review will provide valuable guidance for researchers and producers concerned, and support the promotion of RDI in more horticultural crops.
