“…The use of SS as a substrate also implies a reduction in expenses with CS and chemical fertilizers, as verified by Ribeiro et al (2009) 16 , Uesugi et al (2019) 47 , Cabreira et al (2021) 7 , and the present study. Furthermore, CRF and peat are imported to Brazil and other underdeveloped countries.…”

Schinus terebinthifolia Raddi is a species with several potential uses; selecting the proper substrate and fertilizer rate can be vital for seedling production in a nursery environment. This study aims to evaluate two substrates, namely: (i) sewage sludge (SS) from Ilha WWTP; (ii) a commercial substrate (CS) made of organic materials (mainly sphagnum peat). Increasing rates of controlled-release fertilizer – CRF (0, 3, 6, and 12 kg m−3) were applied. The experiment was completely randomized with a factorial 2 × 4 scheme (substrates × rates). The seedlings’ growth, biomass, and quality were evaluated. The treatments were compared by Tukey test and regression analysis, where linear, quadratic, and cubic models were considered. Principal components analysis (PCA) and cluster analysis were performed. The CRF rates showed non-significant effects for most of the investigated variables in the SS substrate. In the CS, a 7.8 kg m−3 rate of CRF showed the best growth performance. The multivariate analysis of the morphological parameters proved suitable as a complementary approach to evaluate the seedlings’ quality. Seedlings reached recommended values for height, diameter, and quality in the 100% SS substrate without chemical fertilizers; thus, Schinus terebinthifolia production in the SS from Ilha is recommended. Besides the growth advantage, the SS can promote nursery cost savings with commercial substrates and chemical fertilizers.

“…In this analysis, was considered a gross revenue of 20% over TPC, independently of the applied irrigation depth, since it is a commonly used margin within the forestry market. Was considered the Simplified National Tax (4.0% of revenues) due the production capacity considered for the nursery, i.e., 300 thousand seedlings per year (UESUGI et al, 2019).…”

ResumoAvaliação econômica da produção de Eucalyptus urograndis em dois tipos de recipientes. O tratamento sistemático das incertezas associadas aos processos produtivos florestais, permite o estabelecimento de estratégias técnicas-gerenciais para a mitigação do risco inerente à aplicação de capital demando para a produção de mudas. Assim, nosso objetivo foi a análise do risco unitário para a produção de mudas de Eucalyptus usando o método de simulação de Monte Carlo. Pautado na estimativa do cálculo do custo da produção das mudas de Eucalyptus e, nas receitas esperadas de seis sistemas produtivos, caracterizados como projetos de investimento florestal, foi possível a construção dos fluxos de caixa, conseguinte, a adoção de métricas empregadas para a decisão de projetos de investimento mutuamente excludentes. A incorporação da análise de risco teve como proposições as incertezas associadas aos fatores produtivos, aos quais foram atribuídas distribuições de probabilidades. Em seguida, foram gerados números pseudoaleatórios mediante à simulação pelo método de Monte Carlo, com o propósito de mensurar os valores econômicos estocásticos e as probabilidades de ocorrências para as métricas dos projetos. Os resultados estocásticos demonstraram que a probabilidade de viabilidade econômico para as condições analisadas é nula; as variáveis estocásticas mais críticas dos projetos florestais são os investimentos e o ciclo de produção de mudas. Palavras-chave: Risco, custo de produção, Monte Carlo, viveiro, valor presente líquido.

“…Previous research has addressed sexual (Scalon et al 2012;Ghio et al 2021) and asexual propagation (Biganzoli et al 2021) generating replicable protocols on a commercial scale. Other studies have evaluated the effect of light intensity (Alvarenga et al 2003), nutritional deficiencies (Sorreano et al 2008(Sorreano et al , 2011, and production costs for seedlings of C. urucurana in different types of substrates and fertilizers in container-grown plants (Uesugi et al 2019). The survival rate of C. urucurana seedlings has also been evaluated in the restoration of natural forests under different environmental conditions (de Oliveira et al 2012;Lima et al 2016;Fragoso et al 2016).…”

“Sangre de Drago” (Croton urucurana Baill.) is a native tree of South America with high value for urban afforestation or the restoration of riparian forests. This study aimed to evaluate the effect of container size and fertilization on the quality of seedlings produced in a plug+1 system. In the establishment phase, the impact of container size (110 mL or 250 mL) and fertilization (with or without) on seedling quality were evaluated before transplanting into bigger containers. In the rapid growth phase, the effect of container size (1 L, 1.5 L, and 3.5 L) on survival and seedling quality was evaluated. At the end of each phase, seedling quality was evaluated through morphological and physiological attributes. Data were analyzed through linear models, generalized linear models, and nonlinear regressions. In the establishment phase, seedlings grown in 250 mL containers with fertilization showed the best performance in morphological and physiological variables and the Dickson quality index. In the rapid growth phase, seedlings grown in 3.5 L containers showed the highest values in total height, stem diameter, total dry weight, Dickson quality index, and the lowest mortality at the end of the experiment. We recommended 250 mL containers with fertilization in the establishment phase until the seedling can be lifted with its intact root ball. We then transplant it into 3.5 L containers for the rapid growth and hardening phases until out-planting.
