The research aim was to evaluate the survival of Eucalyptus urograndis clone H13 selected for water deficit, under two water management for nursery, with and without the addition of hydro absorbent polymers (hydrogel), planted in two soils. The plantation was done in vases kept in greenhouse with two different soil textures: sandy and clay. Each vase received 2.5 L of soil, one liter of water and 0.4 g (120 mL of polymer) of hydro absorbent polymers. The experimental delineation was totally randomized, with three repetitions. The water deficit symptoms at different levels always appeared first in plants of vases with clay soil, starting in those that were kept without water stress in the nursery phase. Assuring the plants survival in a period without water varying from 14 to 20 days (with and without hydrogel, respectively), while for sandy soil, plants survived from 29 to 34 days (with and without hydrogel, respectively). Despite no statistically significant results with the hydrogel, it allows great operational flexibility for intervention with new irrigation in both soils.
