Rational irrigation and chemical nitrogen fertilizer increase crop yield, water productivity (WP), and nitrogen-use efficiency (NUE), but excessive amounts of water and nitrogen increase nitrogen loss and negatively affect the soil and environment. Controlled-release fertilizers and organic fertiliz...
