^aWD, Water-deficit treatment harvested at FTSW of 0.08; WD fb RW, water deficit followed by rewatering harvested at FTSW = 0.6; WW, well watered harvested at FTSW = 0.6.

^bRelative ARA indicates ARA for the different soil-water treatments as a fraction of rate for the well-watered control.

^cUreide concentration of uppermost fully expanded trifoliate as determined from leaf discs taken at harvest.
