The water use was highest under field capacity conditions, lower
under mild water stress and lowest under severe drought stress
(Table 3.). The range in values of water use under well water was
60.06e65.07 L pot1. Under mild water stress, the amount of water
use ranged from 30.00 to 32.10 L pot1. Under severe water stress,
the amount of water use ranged from 17.00 to 19.00 L pot1. In three
water conditions, differences among Jerusalem artichoke genotypes
were significant for water use. JA 125 showed the highest water use across the three water levels.
