Hydrogel in the seedling growth of Eucalyptus dunnii Maiden under different irrigation management
This study evaluated the effect of using hydrogel in the planting of Eucalyptus dunnii seedlings in pots, under different water-management regimens. Seedlings of approximately 25 cm height were planted in pots filled with 4.5 L of soil. The experiment was of Completely Randomized Design, in a 2x3 fa...
