Abstract

Soil salinity is one of the major causes of abiotic stress that limits crop productivity. It also affects nearly one-fifth of the worldwide cultivated lands. The negative effects of soil salinity in plants are related to the specific toxicity of ions, such as Na and Cl, as well as to the low osmotic potential of soil solution, which results in water deficiency in plant cells. These conditions make it difficult for a plant to absorb water from saline soils and/or lead to ionic effect resulting from accumulation of toxic salt ions which leads to the reduced growth rates and productivity. Recently, nanotechnology has gained the attentions of scientists in various disciplines of science and plays a vital role in medicine, industries, agriculture, electronics, energy, and environment. In agriculture, using nanoparticles is expected to improve the crop productivity by enhancing plant nutrition, precision farming, water use efficiency, crop protection against pest and diseases by molecular tools and techniques, and environmental protection. Thus, the aim of the chapter is to provide an update on the use of various types of nanoparticles for alleviating the salt stress and also to understand the mechanism behind it.
