In a study on optimizing water use for maize in northwest China, researchers found that adjusting irrigation intervals can increase grain yield and water use efficiency. By testing different irrigation schedules, they discovered that irrigating every 6 days led to the highest yield and efficiency. This interval helped maintain ideal soil moisture levels, reducing water loss and maximizing crop production. This approach could benefit similar arid regions by improving maize yield and water efficiency with mulching and drip irrigation.
