In arid fields where water is already a gamble, a two-year study offers farmers something rarer than rain: a different way of thinking about resilience. Researchers in drought-prone regions found that growing barley and chickpea together, nourished by organic nitrogen rather than synthetic fertilizers, significantly cushioned the blow of water stress — losses that otherwise reached 64 percent of a harvest. The finding is less about a single crop or a single input and more about the wisdom of designing agricultural systems that cooperate with natural processes rather than override them.
