Treatments based on the percentage of daily evapotranspiration (ET) imposed at 41 d after planting, average soil moisture, mean temperature, chamber CO2 concentration, vapor pressure deficits (VPD), and evapotranspiration (ET) during the experimental period for each treatment.
† Soil moisture values are averaged for each treatment from 41 to 126 days after planting. Values within a column with the different letter are significantly different at P<0.05.
