Abiotic Stress Moderation and Crop Production in Changing Climate: Beneficialtrace Elements: Review

Concerns around food security have emerged in recent years, with rising food demand and the options to meet. The FAO projections indicate that global food demand may increase by 70 percent by 2050, with much of the projected increase in demand for major food crops expectedly coming from soaring population and their dietary changes.Moreover, various abiotic stresses accentuated with changing climate has jeopardized the crop production scenario. Ensuring secured food production in the face of climate change is a formidable challenge. Furthermore, in the post-green revolution period, practice of intensive cultivationand extravagant usage of high analysis fertilizers to over-responsive high yielding cultivars have caused havoc micronutrient mining from the soil itself and thus backfired on sustainable food production. In addition to micronutrients, certain beneficial elements are found to be very useful withbetter plant physiology led crop production and nutritive value of the consumables. These elements are collectively referred to as beneficial-trace elements and play a stellar role in moderating various abiotic stresses. Therefore, the application of beneficial-trace elementsas soil and foliar application is needed to be focusedon toassure quality food production through ensuring their effects on crop physiology
