Global food production depends on agricultural yields, yet crops face various environmental stresses that cause significant harvest losses. While individual and combined biotic and abiotic stresses have received attention, the effects of multiple concurrent stresses remain poorly studied. Nanofertilizers offer a promising approach for agricultural sustainability, serving as alternatives that mitigate the health and environmental risks linked to conventional fertilizers. These nanonutrients can assist cultivated plants experiencing different stresses, helping to enhance crop yields both qualitatively and quantitatively. Despite their potential, substantial questions remain regarding the readiness of nanofertilizers to become the primary nutrient source in modern farming, the specific efficacy of biologically synthesised variants, and the full extent of crop damage caused by multiple environmental stresses.
Modern agriculture must feed a growing global population while coping with climate and biological stresses that undermine crop yields. Nanofertilizers could provide a cleaner, more targeted way to supply essential nutrients without the negative side effects of conventional agrochemicals, potentially safeguarding food security under challenging environmental conditions.
The potential application centres on developing nanofertilizers, including biologically synthesised formulations, for crop growers facing environmental stresses. Based entirely on the abstract, this concept is at an early research stage, as fundamental questions remain regarding their dominance in modern farming, practical efficacy under multiple stresses, and general readiness for broad commercial adoption.

The global food production for the worldwide population mainly depends on the huge contributions of the agricultural sector. The cultivated crops of foods need various elements or nutrients to complete their growth, and these are indirectly consumed by humans. During this production, several environmental constraints or stresses may cause losses in the global agricultural production. These obstacles may include abiotic and biotic stresses, which have already been studied in both individual and combined cases. However, there are very few studies on multiple stresses. On the basis of the myriad benefits of nanotechnology in agriculture, nanofertilizers (or nanonutrients) have become promising tools for agricultural sustainability. Nanofertilizers are also the proper solution to overcoming the environmental and health problems that can result from conventional fertilizers. The role of nanofertilizers has increased, especially under different environmental stresses, which can include individual, combined, and multiple stresses. The stresses are most commonly the result of nature; however, studies are still needed on the different stress levels. Nanofertilizers can play a crucial role in supporting cultivated plants under stress and in improving the plant yield, both quantitatively and qualitatively. Similar to other biological issues, many open-ended questions still require further investigation: Is the right time and era for nanofertilizers in agriculture? Will the nanofertilizers be the dominant source of nutrients in modern agriculture? Are nanofertilizers, and particularly biological synthesized ones, the magic solution for sustainable agriculture? What are the expected damages of multiple stresses on plants?
