DW, dry weight; Values followed by the different letters within a column are significantly different at 0.05 probability level; CVS was calculated from the data of three shading treatments in normal planting date of 25 April; CVP was calculated from the data of three planting dates and CVP×S was calculated from the data of all treatments; * and ** mean significant difference at 0.05 and 0.01 probability levels, respectively; NS means non-significant differences.
