Optimization of deficit irrigation and nitrogen fertilizer management for peanut production in an arid region

Abstract Deficit irrigation (DI) has been emerging as an important technique for enhancing crop water productivity (WP). However, advantage of DI under varying nitrogen (N) application rates remains unclear. Field experiments were conducted during 2012–2014 to investigate the impacts of six irrigati...
