Figure 8. Cumulative biomass production of Wytana saltbush, Big saltbush, and Maritime barley grown in columns with water table positions at 114, 76, and 38 cm below the sand surface. Columns planted to the same species and identified by the same letter are not significantly different at alpha = 0.05. Wytana saltbush and Big saltbush biomass production did not differ significantly from one another, but both were significantly different than Maritime barley at p=0.10.
