At the current rate of population growth, the global population\udis expected to touch at least 9 billion in 2050 (Godfray et al.\ud2010), putting an excessive pressure on the food, feed and fuel\udsupply. To meet this challenge, food supply will need to grow\udannually by 2–3% (Hawkesford et al. 2013). In the past, global\udfood production has largely been driven by the development of\uddwarf varieties that are responsive to high inputs (both water\udand fertilizers), which had negative impact on the environment\udleading to decline in crop yields and widening the gap between\udpotential and realized yields. This has been further exacerbated\udby the yield losses of up to 40% due to the diseases and pests\ud(Oerke 2006). Abiotic stresses such as drought (due to uncertain\udand irregular rains), heat (due to rise in temperature), salinity,\udmineral toxicities and nutrient deficiencies contribute to either\uddecline in productivity or complete failure of crops
