Plant Stress: Challenges and Management in the New Decade

Abstract

Agriculture is one of the important sources to fulfill the demand of human food requirements. The conventional methods of increasing crop production presently depend upon chemical substances, which are harmful to the environment as a major proportion of the applied chemicals get accumulated in the environment. Therefore, a sustainable and environment-friendly method to produce food from comparatively diminishing agricultural fields to feed the rapidly growing world population is the need of the hour. To address the present scenario, nanotechnology has emerged as a potential tool for the development of sustainable and productive agricultural systems. Nanoparticles owing to their tiny size and surface chemistry are relatively easier to be absorbed by plants and most importantly impart negligible toxic effects on the agricultural system. The other advantages of using nanoparticles lie within their flexibility in shape, size, solubility, and other features, which make them a suitable carrier for beneficial agrochemicals. Therefore, this chapter will focus on the different types of nanoparticles available, their mechanism of uptake, and their potential to stimulate crop improvement either by directly boosting the plant growth or by indirectly managing the losses incurred due to the effects of abiotic or biotic stresses.
