Root dry weight (g per plant) of potted single tomato plants (n = 3) measured at 57, 85, and 99 days after sowing (DAS) for the 6 post-infiltration aeration treatments (i.e. none or 2.5 liter aeration applied during 5 different periods) at the low and high irrigation levels (i.e. subsurface drip-irrigation to maintain soil at 60 to 70% and 70 to 80% of volumetric field capacity).

Notes: Irrigation and interaction effects were not significant (p>0.05) in ANOVA. Aeration treatment means at each irrigation level not followed by the same letter are significantly different at the 5% level
