ABSTRACT:      Studies on the early development of forest species usually only analyze their nursery growth, not taking the post planting into account. Therefore, this study aimed to evaluate the survival and growth under nursery and field conditions of Enterolobium contortisiliquum seedlings produced with different container volumes and controlled-release fertilizer (CRF) doses. The treatments were composed of two containers volumes (110 and 180 cm3) with five CRF doses (0; 3; 5; 7; and 9 g L-1). At the nursery, at 150 days after sowing, the following attributes were evaluated: height (H); stem diameter (SD); shoot (SDM), root (RDM) and total dry matter (TDM); and Dickson quality index (DQI). At 360 days after the field planting, the survival, H and SD were measured. It was found interaction between factors for SD and significant effects of container volume for SDM, RDM, TDM and DQI. The maximum technical efficiency dose (MTED) of CRF in the nursery ranged from 6.50 to 9.74 g L-1. This allowed recommending the CRF dose for the fast seedling outplanting. The negative effects from base fertilization absence were identified on the seedlings field survival, yet there was no influence of the tested treatments on their growth 360 days after planting. For producing Enterolobium contortisiliquum seedlings, it is recommended using 110 cm3 containers with a CRF dose of 3 g L-1, which provides suitable performance on the outplanting and after it. However, doses above 7 g L-1 can reduce the seedlings nursery time in about six months after sowing.

RESUMO:   Estudos abordando o desenvolvimento de espécies florestais na fase inicial de estabelecimento, via de regra, analisa apenas seu crescimento em viveiro, não considerando a fase de pós-plantio. Desse modo, este estudo objetivou avaliar a sobrevivência e o crescimento, em viveiro e a campo, de mudas de Enterolobium contortisiliquum produzidas com diferentes volumes de recipientes e doses de fertilizante de liberação controlada (FLC). Os tratamentos constituíram-se de dois volumes de  recipientes  (110  e  180  cm3) combinados com cinco doses de FLC (0, 3, 5, 7 e 9 g L-1).  No  viveiro,  aos  150  dias  após  o  semeio, avaliaram-se a altura (H), o diâmetro do coleto (DC), as matérias secas da parte aérea (MSPA), radicular (MSR) e total (MST), e o índice de qualidade de Dickson (IQD). Aos 360 dias após o plantio no campo, avaliaram-se a sobrevivência, H e DC. Constatou-se a interação para DC, assim como o efeito do volume do recipiente na MSPA, MSR, MST e IQD. A dose de máxima eficiência técnica (DMET) de FLC em viveiro variou entre 6,50 e e 9,74 g L-1. Isso permitiu inferir sobre a dose necessária para rápida expedição das mudas ao campo. Observou-se os efeitos negativos da ausência de adubação de base na sobrevivência das plantas no campo, porém não houve influência dos tratamentos testados sobre o crescimento das mudas após 360 dias do plantio. Na produção de mudas de Enterolobium contortisiliquum, a utilização do tubete de 110 cm3 conjuntamente com a dose de 3 g L-1de FLC, proporcionam desempenho adequado das mudas no pós-plantio. Entretanto, doses superiores a 7 g L-1podem acelerar a expedição das mudas do viveiro para cerca de seis meses após semeadura.
