ABSTRACT
Water scarcity is now one of the major problem all over the world and it will be more challenging in nearby future. This water scarcity is going more and more threatened as the human population is increasing and food requirement is also growing along with the issues of climatic changes. Drought stress is taken as one of the major problem to food security, as it reduces the plant growth, its production and also the quality of major agricultural crops. It hinders the cell division and reduces photosynthates and reduces plant growth, crop productivity, decreases CO2 assimilation, minimizes the leaf water potential, closes stomata and reduces chlorophyll synthesis. In addition to this, it also affects the nutrient metabolism, translocation, respiration and carbohydrate metabolism. Silicon shows a major performance in increasing the drought tolerance in plant and improves its productivity. The physiological importance of silicon includes maximum water uptake by roots, maintenance of nutrient stability, minimized transpiration and increased photosynthesis rate. The increased activity of photosynthetic enzymes, regulation of endogenous plant hormones and osmotic adjustment also occurs by silicon. So, keeping in view the importance of silicon, the present review aims to explain the important aspects of silicon on crops and how it will work in alleviating drought stress.
