Alternate partial root-zone drip irrigation improves water– and nitrogen– use efficiencies of sweet-waxy maize with nitrogen fertigation

Abstract Alternate partial root–zone drip irrigation (ADI) or fertigation has favorable effect on crop water- and nitrogen- use efficiencies (WUE and NUE). However, the advantage of combined application of ADI and nitrogen fertigation on crop WUE and NUE remains unclear. A pot experiment was conduct...
