| Popis: | The vigor of ‘Washington’ navel orange and ‘Balady’ mandarin trees was inversely associated with the depth of the water table. The tree height varied from 302 to 93 cm for ‘Washington’ navel orange and from 222 to 103 cm for ‘Balady’ mandarin at water table depths of 171 to 53 cm in the former and 158 to 89 cm in the latter case. The total amount of feeder roots ranged from 521 to 54 g dry weight per tree in the ‘Washington’ naval orange and from 558 to 89 g per tree in the ‘Balady’ mandarin. The total new leaf area produced per tree per year decreased sharply in both varieties with increased shallowness of the water table. For both varieties, not much differences in per cent Na, K, Ca, Mg, Cl, P and N in spring leaves or roots were found with respect to the varying depth of water table. Yield decreased sharply as the water table became closer to the soil surface in both varieties. |
