The effect of MCEW on seed cotton yield under different drip irrigation amounts (Han et al. 2017). MCEW represents a 25% mepiquat chloride emulsion in water; MT, MC1, MC2 and MC3 represent manual topping as control, 450, 750 and 1 050 mL·hm−2 MCEW, respectively. For each year, bars with different letters are significantly different at P < 0.05
