Effects of Irrigation and Nitrogen Supply on Grain Yield,Water Use Efficiency and Apparent Nitrogen Recovery Fraction of Spring Wheat on No-tillage Farmland with Standing Stubble
|
Abstract:
A controlled experiment was conducted in oases of the Shiyanghe river basin to investigate the effects of different irrigation and nitrogen supply levels on grain yield,straw yield,harvest index(HI),water use efficiency(WUE) and apparent nitrogen recovery fraction(NF) of spring wheat on no-tillage farmland with standing stubble.A complete randomized block split-plot design was employed with different irrigation regimes,namely conventional irrigation of 327 mm,20% water-saving irrigation of 261 mm,40% water-...
