Abstract

CARNEVALI, Thiago de Oliveira et al. Nutritional study of Schinus terebinthifolius (Raddi) in response to potassium fertilization. Ciênc. Florest. [online]. 2019, vol.29, n.2, pp.824-833.  Epub Sep 30, 2019. ISSN 0103-9954.  http://dx.doi.org/10.5902/198050988312.

The objective of this work was to evaluate the effect of K doses on the initial development and nutritional efficiency of Brazilian pepper tree. For this purpose it was developed under greenhouse conditions in pot experiment with five level of K2O (66.67, 133.33, 200, 266.67 and 333.33 mg kg-1) a randomized complete block design with five replicates. At 180 days after transplant, all plants were harvested and evaluated for height, diameter, leaf area, root and shoot dry mass, root and shoot contents, and efficiency of uptake, use and translocation of nutrients. Potassium fertilization increased the development of Brazilian pepper tree, the highest plant height and stem diameter were obtained when the plants were grown with 210 mg kg-1 K2O and the highest dry shoot mass, leaf area and nutrient content cultivating with the dose of 66,67 mg kg-1 de K2O.

Keywords : Brazilian pepper tree; Nutritional efficiency; Initial growth.
