- Abstract
Establishing relationships between water consumption by the eucalyptus crop and the availability of water on the substrate of seedling cultivation or post-planting soil, contributes to the prediction of the productive potential of the forest plantations. The objective of this study was to evaluate the initial development of eucalyptus seedlings in the growth and rustification phases, using irrigation water slides and soil tension. The experiment was conducted in a completely randomized design with six treatments, four slides based on reference evapotranspiration - ETo (50, 100, 200, 300% of ETo) and two treatments based on water tension in the substrate (3 and 6 kPa) with four replicates. There were no significant differences between the treatments 100, 200, 300% of the ETo and the soil water tension of 6 kPa for height of the seedlings. The seedlings had a similar behavior in relation to stem diameter growth in the growing phase, while in the rustification phase the 300% ETo depth provided higher growth, a similar result for shoot and root dry matter and number of leaves. It was concluded that the larger irrigation slides (300% of ETo) provided the greatest development of the seedlings, reaching defined standards for their expedition and subsequent planting. Irrigation management via soil water stress (3 and 6 kPa) and 50% of ETo limit the development of eucalyptus seedlings E. grandis. E. urophylla - 6064 for commercial and transplanting purposes.
