Farmers in Semiarid China Boost Wheat Yields, Profits with Rainwater Harvesting
In the study, researchers wanted to improve wheat growth using less water in dry areas. They tested different irrigation methods from 2015 to 2017 in China. By combining rainwater harvesting with reduced watering, they found a method (R75) that saved water and boosted wheat yield. This method used less water but produced more wheat compared to traditional ways. The R75 method led to higher soil water levels, lower water evaporation, and increased crop productivity. It also showed better plant growth and more profit for farmers. Overall, this strategy can help farmers save water, increase crop yield, and make more money in dry regions.
