Effect of conservation tillage on crop productivity and nitrogen use efficiency
Soil and Tillage Research（2019）
Abstract
•Nitrogen use efficiency (NUE) decreased in general with increasing N level.•Yield increased from N1 to N2 and changed inconsistently from N2 to N3.•Medium N level (N2) is most suitable from the NUE and yield viewpoints.•Soil type and tillage systems have significant influence on soil physical properties.•Maize and winter wheat yields respond positively to a conservation tillage system.
