Effect of planning methods and deficit irrigation on plant height (cm), shelling percentage and harvest index of maize.
Note: RM: Ridge planting method; FM: Flat planting method; BM: Broadcast planting method and D0: Full irrigation (10 irrigation); D1: Deficit irrigation (one irrigation missing at six leaves stages); D2: Deficit irrigation (one irrigation missing at twelve stage); D3: Deficit irrigation (one irrigation missing at flowering stage); D4: Deficit irrigation (one irrigation missing at grain filling stage). The vertical bars represents the mean ± the standard error of the mean (n=3).
