“…The linear regression, with increment of 30.6% in the stem diameter compared to the control, also showed a good response to nitrogen by K. senegalensis A. Juss in the initial development phase. Stem diameter is one of the most important parameters to estimate survival, after planting of seedlings of different forest species (Afonso et al, 2017). However, as reported in several studies, gains from N supply are much more modest or in some cases are absent in initial seedling growth.…”

African mahogany is an exotic specie and its cultivation has increased in Brazil due to the high value of its timber on the international market. Nutrition with nitrogen is an important factor for species with high biomass production and specific studies on this species are essential. The present study aimed to assess the initial growth of African mahogany plants submitted to nitrogen fertilization. The experiment was set up and carried out in a greenhouse, with 7 dm3 plastic pots using a oxisoil sampled from the surface layer. A completely randomized experimental design was used with five treatments and six replications. The treatments consisted of five N levels: 0, 40, 80, 120 and 160 mg dm-3, using urea as the source. The following were assessed at 180 days: height, stem diameter, leaf, stem, root and total dry matter, N content in the leaves in the African mahogany leaves. The African mahogany seedlings had high N demand and responded positively to the N used and the growth variables was positive with increase in N level. However, as it presented increasing linear effect, the N level can not be estimated, that would provide the maximum initial development for this plant species.

“…Os valores de clorofila A e B, entre os tratamentos testados não houve diferença estatística (Tabela 3). A clorofila, além dos pigmentos acessórios, é fundamental à planta na captação de energia solar, eficiência, crescimento e adaptabilidade das plantas (Afonso et al, 2017). Corroboram com estes resultados o estudo de Cruz (2018), que ao trabalhar com as espécies Schizolobium parahyba var.…”

O Cerrado é um bioma do tipo biócoro, que ocupa cerca de 25% do território brasileiro, localizado principalmente na região central. O Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby é uma espécie da família Fabaceae, de ocorrência em mata primária e secundária de terra firme da região amazônica. Esse trabalho tem como objetivo avaliar o desenvolvimento da espécie Schizolobium parahyba var. amazonicum diante de diferentes proporções de substrato alternativo. Foram utilizados 4 tratamentos, distribuídos da seguinte maneira, T1- Substrato Preparado (SP) 100% (Terra preta, esterco bovino e palha de arroz), testemunha, T2- 80% SP + 20% Pó de Rocha (PR), T3- 65% SP + 35% PR, T4-50% SP + 50% PR. O delineamento utilizado foi em blocos casualizados, com 5 repetições e os parâmetros utilizados foram: altura, diâmetro, teor de clorofila, massa seca da raiz (MSR), massa seca da parte aérea (MSPA), massa seca total (MST), razão massa seca da raiz e massa seca da parte aérea (MSR/MSPA), e índice de qualidade de Dickson. A análise de variância e as médias foram comparadas pelo teste de Tukey a 5% de probabilidade através do programa Sisvar. Em todas as variáveis analisadas não houve diferença significativa para todos os tratamentos testados. O uso do pó de rocha como fertilizante não apresentou efeitos significativos no desenvolvimento da espécie estudada.

“…Although it has a lower quantity of nutrients, the Latossolo Vermelho-Amarelo used in the present study presents a higher quantity of clay thus better retaining the nutrients and preventing them from leaching, which may explain the better result for QCB (Table 2). High concentrations of chlorophyll result in high rates of photosynthesis, enabling a greater adaptive capacity after planting (Afonso et al, 2017). Chlorophyll b is considered an accessory pigment that helps the chlorophyll a (Taiz and Zieger, 2013).…”
