Agricultural biotechnology, or genetic engineering, involves modifying organisms’ genetic makeup to improve environmental impact, yield, insect resistance, and nutritional value. Techniques include transgenic approaches, RNA interference, qualitative trait loci mapping, genome-wide association studies, nanotechnology, nanofertilizers, nanopesticides, and nanosensors. These technologies contribute to global food security, sustainability, and economic development. Transgenic approaches introduce foreign genetic material into plant species, while RNA interference controls gene expression, enhancing pest resistance and nutritional value. Nanotechnology also addresses plant diseases and pests, reducing the need for expensive chemical pesticides. Nanoscience focuses on cost-effective nanotechnology applications for seed germination, plant growth, and environmental acclimation. Multi Walled Carbon Nanotubes (MWCNTs) and Iron Oxide nanoparticles have a beneficial effect on the germination and development of seeds. Crop bio-fortification and nutritional content can be improved by genetic engineering. But there are obstacles, such as health hazards and environmental issues. Benefiting marginal areas, advances in genomics may enhance plant breeding for complex features. Nutritional and biological security regulations should consider international agreements, industry standards, and societal risk categories. National, regional, and international standards for risk evaluation and administration form the basis for regulatory regimes. Ethical concerns, such as genetic engineering and life patents, are crucial for understanding the challenges and handling biotechnology. Studies on economic, social, health, and ethical concerns are essential for effective implementation and informed decision-making.
