The study profiles 11 agricultural innovations: crop protection, drip irrigation, drought tolerance, heat tolerance, integrated soil fertility management, no-till farming, nutrient use efficiency, organic agriculture, precision agriculture, sprinkler irrigation, and water harvesting.Findings from the book indicate:No-till farming alone could increase maize yields by 20 per cent, but also irrigating the same no-till fields could increase maize yields by 67 percent in 2050.Nitrogen-use efficiency could increase rice crop yields by 22 per cent, but irrigation increased the yields by another 21 per cent.Heat-tolerant varieties of wheat could increase crop yields from a 17 per cent increase to a 23 percent increase with irrigation.
