Euterpe edulis

Description

  • This article is in Portuguese.
  • This study examines the effect of different doses of phosphorous on the growth of Euterpe edulis, a native palm of the Atlantic Forest.  As for many native species, information on nutritional requirements for E. edulis is lacking.
  • Many native species used in reforestation are grown in low-fertility soils, resulting in unhealthy trees.  Degraded lands in need of reforestation are also low in nutrients, further contributing to the poor growth of trees.
  • The authors experimented with eight different doses of phosphorous: control (no added phosphorous), 90, 180, 270, 360, 450, 540, and 630 mg/dm3.  Twelve months later, the authors measured height and biomass of shoots, collar diameter, belowground biomass, and total root length.
  • The authors found that doses of up to 540 mg/dm3 of phosphorous increase height growth, aboveground biomass, and total biomass; doses of up to 450 mg/dm3 result in a linear increase in belowground biomass; and doses of 270 mg/dm3 result in the greatest increase in stem diameter.  Maximum efficiency of phosphorous use was achieved at a dose of 494.4 mg/dm3 and a height of 28 cm.  The response of root length to additions of phosphorous was not significant.
  • Levels of phosphorous did not affect levels of other macro and micronutrients in the plants.  Macronutrients were found to be present in the following order in aboveground biomass: N> Ca> K> Mg> P>S; in belowground biomass: N> Ca> Mg> S> K> P.  Micronutrients in above and belowground biomass was present in the following order: Fe> Mn> Zn> B> Cu.
