“…Positive results for the variable stem diameter, from using controlled-release fertilizer, were also found in studies with Anadenanthera peregrina and Schinus terebinthifolia Raddi (Rossa et al 2015), Mimosa scabrella (Stüpp et al 2015), Peltophorum dubium (Dutra et al 2016) and Albizia lebbeck (Aguilar et al 2020).…”

Agonandra brasiliensis is a tree from tropical forests, with a wide occurrence in the Brazilian Savannah region. Despite its potential as wood and for reforestarion, efficient protocols for its seedling production are still lacking. This study aimed to assess morphological characteristics for the seedling quality of A. brasiliensis, under nursery conditions, as a function of container volume and controlled-release fertilizer dose. The experiment was carried out in a 2 x 5 factorial scheme, testing two container volumes (1.8 L and 2.2 L) and five doses (0 g L-1, 1 g L-1, 2 g L-1, 4 g L-1 and 8 g L-1) of the encapsulated fertilizer Forth Cote™ (formulation NPK 15-09-12). The plots consisted of five homogeneous seedlings transplanted in polyethylene bags (15 cm x 35 cm) with washed medium sand substrate. The following characteristics were measured: shoot length; stem diameter; increases in length and diameter; total dry matter; shoot and root dry matters and the ratio between them. The Dickson Quality Index was also obtained. The seedling quality for morphological traits, such as shoot length, stem diameter and total dry matter, was especially favoured by treatments combining the controlled-release fertilizer at a dose around 5.0 g L-1 and container volume of 2.2 L.

“…Plants with larger diameters have better survival conditions due to better capacity to growth new roots (Elli et al, 2013). Positive results in the use of CRF for stem collar diameter were also evidenced in studies with Anadenanthera peregrina and Schinus terebinthifolia (Rossa et al, 2015), Mimosa scabrella (Stüpp et al, 2015), Peltophorum dubium (Dutra et al, 2016), and Albizia lebbeck (Aguilar et al, 2020).…”

“…An increasing demand on natural forests for multiuse production requires high quality tree seedlings (Aguilar et al, 2020), which is essential for profitable forest production (Dionisio et al, 2019a). Besides natural forests, reforestation and restoration projects depend mainly on high quality seedlings produced in forest nurseries (Reyes et al, 2014) and, with maximum survivorship rates and rapid initial growth in the field (Marques et al, 2018).…”

The objective of this work was to evaluate seedlings quality of the tree species Agonandra brasiliensis under different doses of the controlled release fertilizer (CRF) Osmocote® and recipient volumes. The experiment was set up in a factorial design for two recipient volumes (1.8 L and 2.2 L) and five CRF doses (0.0; 0.5; 1.0; 2.0; and 3.0 g L-1 of substrate). Four repetitions of one plant each were used. After transplanting seedlings, stem height, stem collar diameter, and the robustness index (RI) were measured in a monthly basis during eight months. The highest seedlings growth was observed with the CRF Osmocote® dose of 2.0 g L-1 and recipients of 2.2 L. The treatment with CRF dose of 2.0 g L-1 in 240 days presented higher initial accumulated growth in height of A. brasiliensis seedlings (mean = 31.38 cm). Seedlings under the dose of 2.0 g L-1 presented 85.90% increase of stem height in relation to the control (substrate without CRF). CRF Osmocote® had positive effect on growth of A. brasiliensis seedlings. Growth was influenced by the different CRF doses and recipient volumes, both for the variables stem height and stem collar diameter and for the RI. The dose 2.0 g L-1 allowed greater accumulated growth in height and diameter in 240 days.

“…of interest needs to exercise greater competition for light (AGUILAR et al, 2020). The result given in the different evaluation periods, such as the 140 DAT period for variable H with gain, was approximately 18%, which fact can be attributed to the addition of the nutrient solution to provide regular supply of nutrients.…”

O objetivo neste trabalho foi determinar aspectos sobre variáveis de crescimento e partição de massa seca das mudas de Khaya senegalensis, bem como a marcha de absorção de nutrientes, em função das épocas e adubação mineral. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 2 x 6. Dois níveis do fator solução nutritiva (sem e com adição) e seis níveis para o fator período (0; 60; 80; 100; 120 e 140 dias). Foram utilizadas 4 repetições, sendo cada uma delas composta de 10 mudas. Para avaliação da qualidade das mudas, consideraram-se os parâmetros morfológicos, relações e índices de qualidade: altura da parte aérea (H; cm); diâmetro do coleto (DC; mm); massa seca da parte aérea (MSPA; g planta-1); massa seca da raiz (MSR; g planta-1); massa seca total (MST = MSPA + MSR; g planta-1); relação massa seca da parte aérea e massa seca da raiz (MSPA/MSR); índice de robustez (IR= H/DC; cm mm-1); e índice de qualidade de Dickson (IQD) e o acúmulo de macronutrientes na parte aérea e sistemaradicular. A adição de solução é recomendada para mudas de Khaya senegalensis a partir da época 100 dias após o transplantio em viveiro de telado na Amazônia setentrional. A manutenção das mudas de Khaya senegalensis com uso de solução nutritiva proporciona as melhores condições para o aproveitamento dos macronutrientes e permite obter mudas aptas para campo em 140 dias após o transplantio em viveiro de telado em Roraima.
