Effects of nitrogen application rate and irrigation regime on growth, yield, and water-nitrogen use efficiency of drip-irrigated winter wheat in the North China Plain

Agricultural Water Management, 2020
Drip irrigation has been gradually adopted for winter wheat production in the North China Plain (NCP) due to significant saving from using irrigation water and improving water and nitrogen use efficiencies.

Response of winter wheat to spring frost from a remote sensing perspective: Damage estimation and influential factors

ISPRS Journal of Photogrammetry and Remote Sensing, 2020
Spring frost is one of the major weather-related threats to winter wheat. The damage to winter wheat caused by spring frost is aggravated by the increase in extreme weather events and the advance of spring phenology driven by a warming climate.
