Nanotechnology showing a promise in current agriculture, for providing new methods to promote plant growth and development. These materials help with efficient nutrient uptake, improve resistance to environmental stress, and speed up growth processes. Because of their tiny size, they have unique qualities that allow precise delivery of nutrients, agrochemicals, and genetic material directly to plant cells. This precision reduces waste and lessens environmental harm. For example, nanofertilizers release nutrients slowly and in a controlled way, ensuring plants get what they need over time and minimizing loss through leaching. This results in better root growth, improved nutrient absorption, and stronger overall plant health. Additionally, nanotechnology has led to smart delivery approaches that react to environmental signals like pH and moisture, making sure plants receive inputs exactly when they are needed. This targeted approach not only boosts plant growth but also cuts unnecessary use of chemical fertilizers, which can harm the environment. Furthermore, nanoparticles can improve plant resistance to both biotic and abiotic stresses. They can carry growth-promoting substances or directly interact with plant cells to kickstart defence mechanisms. The combination of nanotechnology and plant biotechnology creates new possibilities for genetic manipulation, leading to more efficient gene transfer methods. This could result in crops with better traits.
