“…Furthermore, it was suggested that mycorrhizal date palm seedlings could display alterations in cell wall elasticity and water redistribution between apoplastic and symplastic compartments. On this basis, date palm inoculated with AMF can exhibit a better ability to overcome drought stress, thanks to positive effects on physiological attributes, such as stomatal conductance, electrolyte loss/leakage (EL), and RWC [30,90,97,98].…”

“…It was demonstrated that AMF's input leads to the enhancement of sugar and protein content under drought stress. Moreover, mycorrhizal date palm plants exhibit high antioxidant enzyme activities, PPO and POX, for instance [30,90]. PPO catalyzes the formation of quinones involved in cell wall stiffness and resilience to abiotic stresses.…”

“…Drought Organic amendments' application can promote date palm plants' performance under drought stress. In response to water limitations, the organic amendments can improve physiological attributes, such as chlorophyll and carotenoid concentrations, relative water content, leaf water potential, and stomatal conductance in date palm [30,90]. Probably, the organic amendments provide minerals such as N, P, K, and Mg, which are crucial for chlorophyll production [122][123][124].…”

“…Probably, date palm plants can grow better despite water limitations, if an improved nutritional status is provided [118]. In a study carried out by [30], autochthonous PGPR strains contributed to improving date palm seedlings' growth of the "Boufggous" variety, thanks to the uptake enhancement of low-mobility nutrients, such as P and N. Growth traits, such as shoot height, leaf surface, shoot dry weight (SDW), and SFW, were also substantially improved within date palm vitroplants of the "Boufggous" variety, grown under field conditions, thanks to the application of a local PGPR consortium [90]. Moreover, physiological and biochemical properties, such as chlorophyll fluorescence, stomatal conductance, photosynthetic pigments, and osmolytes, were all bacteria-enhanced.…”

Date palm (Phoenix dactylifera L.) is constantly subjected to abiotic stresses. Hence, the application of biostimulants, such as the arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR), and organic amendments hold tremendous potential to significantly improve the growth and yield of date palm. The strengthening of biostimulants’ main common modes of action is exerted through five main functions: biostimulation (essentially), biofertilization, bioprotection, biological control, and the role of bio-effector. Moreover, synergistic and complementary effects manifest through biochemical and nutritional benefits, in addition to molecular modulation. In this regard, the present concise review focuses on highlighting the beneficial impact of AMF and PGPR, as well as the organic amendments, in boosting the health status and productivity of date palm plants subjected to abiotic stresses. Furthermore, mechanisms reinforcing date palm plants’ resilience to abiotic stresses, powered by biostimulants, are particularly emphasized. Based on this review, we could conclude that the overall findings corroborate the beneficial effects of AMF–PGPR and/or compost and manure application in terms of boosting date palm’s growth traits, development, yielding, as well as soil properties under extreme environmental factors, such as those of drought, salinity, and excessive heavy metal(oid)s. Thus, biostimulants can confer resilience to date palm plants against abiotic stresses.

Climate change is a global threat to food security as it causes various biotic and abiotic stresses that adversely disturb agriculture production. With an increase in the worldwide population, the demand for food has also arisen. It is an immediate challenge for the scientific community to introduce an innovative tool to achieve food security with quality plant production and develop tolerance against abiotic stresses, specifically drought. Genetically modifications are effective and time-consuming, while biostimulants are in/organic substances with the potential to support plant development under stress conditions. This chapter focuses on the impacts of climate change on agriculture, challenges for agriculture sustainability and food security, the interrelationship between drought, climate change and food security, the potential role of biostimulants against drought, future aspects and challenges due to climate change specifically drought, and food security challenges. Various studies reported that the application of biostimulants results in enhancement of crop productivity and mitigates the harmful effects due to climate change. To ensure the quality of chapter, we collected references from well-reputed international journals using keywords ““biostimulants,” “drought,” “food security,” “agriculture sustainability,” and “climate change.” In conclusion, biostimulants has a potential to address adverse environmental conditions without affecting crop quality and yield loss.
