Summary

Improving grain yield is a critical challenge for ensuring food security and sustainable agricultural practices, especially in the face of pressing global challenges. The world’s population is projected to reach nearly 10 billion by 2050, increasing the demand for food while arable land is declining due to urbanization, land degradation, and climate change. Moreover, the food security is threatened by various abiotic stresses i.e. water scarcity, extreme temperatures, light intensity, salinity and nutrient deficiencies. Traditional agricultural methods alone are insufficient to meet these challenges; thus, this special issue focuses on multidisciplinary advances that span from molecular mechanisms to sustainable agricultural practices, aiming to explore how genetic improvement, crop physiology, and agronomic management can contribute to enhancing crop yields under changing climatic conditions. Recent advancements in molecular biology, particularly gene editing technologies like CRISPR/Cas9, provide powerful tools for precise genetic improvements. Understanding plant stress physiology and biochemical pathways is crucial for developing crops that can thrive in suboptimal conditions. Furthermore, the integration of digital technologies and precision agriculture can optimize resource use and enhance crop management strategies.

The significance of this research area is underscored by its vital contribution to global food security. As the world’s population continues to rise, innovative approaches are imperative for sustainably enhancing crop yields. The development of resilient crops capable of withstanding abiotic stresses is essential for adapting agricultural practices to fluctuating climate conditions, thereby securing stable food supplies in the face of environmental adversities. By integrating molecular techniques with sustainable agricultural methodologies, this field advocates for resource-efficient farming practices that mitigate environmental impacts. Furthermore, the convergence of diverse scientific disciplines encourages interdisciplinary collaboration, fostering innovation and expediting the formulation of novel strategies for crop improvement. Insights derived from this research can profoundly influence agricultural policies, directing investments and practices that bolster sustainable agriculture and food security. Additionally, improvements in crop yields are critical for the economic sustainability of farming, empowering farmers to thrive in an increasingly competitive market landscape. In essence, by deepening our understanding of molecular mechanisms and their agricultural applications, this research area plays a transformative role in shaping the future of global food systems and promoting sustainable agricultural practices.
