Abstract

Increasing population pressure and growing constraints on cultivable land and water resources necessitate improving resource use efficiency through the adoption of advanced and efficient agricultural technologies. With finite resources and a growing global population, agriculture has become increasingly essential as a source of food, fiber, and livestock. Due to their eco-friendly nature, the integration of crop improvement strategies with nanotechnology and plant biostimulants (PB) plays an important role in the development of smart and sustainable agriculture. Improved agricultural techniques have the potential to transform agricultural systems, and as a result, could be a viable option to increase crop yields. The use of advanced technologies such as nanosensors and nanofertilizers derived from nanotechnology has offered promising ways to modernize the farming sector. The usage of nano products might be a reliable answer to increase crop yield to ensure food security. Due to its advantages over conventional agriculture in terms of being safer and healthier for humans, organic farming has attracted a great deal of interest from both consumers and experts. In addition, PB can boost plant resilience and optimize nutrient uptake efficiency, helping to reduce the yield gap between conventional and organic farming. This study investigates the role of nanotechnology and biostimulants in promoting sustainable agriculture and improving crop management practices at the field level. Researchers can use these to grasp the importance of nanotechnology and PB analyse future conditions, and develop strategies to maintain food and nutritional security. This review uniquely integrates nanotechnology and biostimulants within a unified mechanistic framework. We propose a conceptual framework describing how nanocarriers enhance biostimulant stability, signaling, nutrient uptake, and stress resilience, offering a new direction for nano-bioformulation design.
