Abstract

VARGAS, Giovanno de  and  MARQUES, Renato. Growth and Nutrition of Angico and Canafístula under Liming and Gypsum. Floresta Ambient. [online]. 2017, vol.24, e20160102.  Epub Apr 27, 2017. ISSN 1415-0980.  http://dx.doi.org/10.1590/2179-8087.010216.

This study aimed to evaluate the effect of lime and gypsum application on the growth and nutrition of two leguminous trees. Treatments consisted of five rates of limestone, gypsum and a control treatment, with five replicates. Angico species (Anadanthera colubrina) and canafístula (Senna multijuga) were tested in a greenhouse experiment. Height and diameter were evaluated for a period of seven months. We evaluated the plants biomass, chemical composition, and number and dry weight of nodules on the roots. Lime increased pH, Ca2+ and Mg2+ content in soils, besides the neutralization of the Al3+. For Angico, basis saturation promoted the highest growth for canafístula it was 20%. Foliar nutritional content in the species, both, followed the order N> Ca> Mg> K> P. There were no correlations between plant growth and leaf content of nutrients.

Keywords : Anadanthera colubrina; Senna multijuga; native forest species; soil fertility.
