 Soil water dynamics and water use efficiency in spring maize (Zea mays L.) fields subjected to different water management practices on the Loess Plateau, ChinaYi Liu, Shiqing Li, Fang Chen, Shenjiao Yang and Xinping Chen Agricultural Water Management, 2010, vol. 97, issue 5, 769-775 Abstract: Soil water supply is the main limiting factor to crop production across the Loess Plateau, China. A 2-year field experiment was conducted at the Changwu agro-ecosystem research station to evaluate various water management practices for achieving favorable grain yield (GY) with high water use efficiency (WUE) of spring maize (Zea mays L.). Four practices were examined: a rain-fed (RF) system as the control; supplementary irrigation (SI); film mulching (FM); and straw mulching (SM) (in 2008 only). The soil profile water storage (W) and the crop evapotranspiration (ET) levels were studied during the maize growing season, and the GY as well as the WUE were also compared. The results showed that mean soil water storage in the top 200cm of the profile was significantly (P Keywords: Loess; plateau; Water; management; practice; Spring; maize; Soil; water; storage; Evapotranspiration; Water; use; efficiency (search for similar items in EconPapers) Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:eee:agiwat:v:97:y:2010:i:5:p:769-775 Access Statistics for this article Agricultural Water Management is currently edited by B.E.
