Germination and Development of Enterolobium contortisiliquum (Vell.) Morong Seedlings Produced in Commercial Substrate and Rice Bark in Natura

Abstract

Enterolobium contortisiliquum (Vell.) Morong, (Mimosoideae, Fabaceae) occurs throughout Brazil, is used in the recovery of degraded areas. The objective was to evaluate the influence of raw rice in natura to produce E. contortisiliquum seedlings. It consisted of four treatments, it was used the randomized block design. The characteristics evaluated were: height (H) and stem diameter (SD), number of leaves and stem dry matter (SDM) and root dry matter (RDM). From these data were calculated quality indicators of the seedlings and growth curves. It was conclude that to produce seedlings of E. contortisiliquum with a suitable quality standard recommends the use of at most 50% of raw rice in natura + 50% commercial substrate.
