Environmental conditions for the study site, covering the periods of data collection. a Daily vapor pressure deficit (VPD) in kPa is shown as a red dashed line and sunlight, represented by photosynthetically active radiation (PAR), is displayed as a black solid line. b Average values of volumetric soil moisture (m3 m−3) are displayed as solid points with one standard deviation shown as an error bar. Gray line represents 70% of the field capacity of the soil at our site. Blue and red shaded regions show collection period in the wet and dry seasons, respectively
