“…The biometric parameters evaluated for the SRF2 fertilizer showed a quadratic behavior in relation to the doses of applied fertilizers, as observed for Cordia trichotoma (Berghetti et al 2016), Aspidosperma parvifolium (Menegatti et al,201) and Dipteryx alata (Aguilar et al 2020). However, the use of SRF1 had a positive linear effect, as found by Gonçalves et al ( 2013) and Goulart et al (2007) studying the application of doses of readily soluble nitrogen fertilizers, on height, in seedlings of Mimosa caesalpiniaefolia and Tabebuia serratifolia.…”

“…Thus evincing a relation between these two factors in the production of Handroanthus impetiginosus. The lowest growth observed was found for the treatment without fertilization, which proves the need for nutritional complementation for the formation of seedlings with quality, regardless of the substrate composition, as verified by Aguilar et al (2020).…”

A espécie Handroanthus impetiginosus possui grande interesse econômico devido a qualidade da sua madeira. Visando entender e ampliar os conhecimentos sobre a sua formação de mudas com qualidade da espécie, foi estudado a eficiência e as doses adequadas de dois adubos de liberação lenta na produção de mudas de Handroanthus impetiginosus. O experimento foi conduzido em delineamento em blocos casualizados, em fatorial (2x5). Foram avaliados dois adubos (SRF1 e o SRF2) em cinco doses (0, 3, 6, 9, 12 kg dm-³). Foram mensurados a altura, diâmetro de coleto, H/SD, massa seca da parte aérea, do sistema radicular e total, e o Índice de Qualidade de Dickson. Para cada variável foi calculado a dose máxima de eficiência técnica (MDTE). Realizou-se a análise de variância e a comparação de médias pelo teste Tukey para os dois adubos utilizados e análise de regressão das médias para as doses utilizadas. Todas as análises foram realizadas utilizando o software R. Todas as variáveis apresentaram crescimento quadrático positivo. Os resultados deste estudo indicam que ambos os adubos são adequados para produção de mudas de Handroanthus impetiginosus, nas MDTE de 11,65 kg dm-3 para SRF1 e 9,19 kg dm-3 para SRF2.

“…Other authors also reported that adopting containers with this volume benefits plant growth (Butzke et al 2018;Freitas et al 2021;Gasparin et al 2015). The results suggest that the smaller volume of the container limits the space for root expansion, in addition to reducing the availability of water, nutrients, and organic matter for seedling development, compromising their growth, both in the root axis and the aerial axis (Aguilar et al 2020;Cruz et al 2016;Dias et al 2016). The lower biomass accumulation, both in the shoot and the roots, evidence this fact.…”

“…The Dickson quality index is an efficient indicator of seedlings' quality since it includes multiple morphophysiological variables. It is emphasized that the higher the index value, the more vigorous the seedling is (Aguilar et al 2020). Some authors mention that the minimum value for this index would be 0.2.…”

Production of Nephelium lappaceum Seedlings using Different Volumes of Tubes and Cultivation Densities

et al. 2023

Rambutan (Nephelium lappaceum) fruit is a potential non-timber forest in tropical countries such as Indonesia due to its high economic potential. However, it is necessary to know the silvicultural aspects of the species in order to produce high-quality seedlings. The volume of the tube used and the spacing between seedlings can influence the quality of the seedlings. Thus, this work aimed to evaluate the production of seedlings of N. lappaceum through different densities of seedlings per tray and volumes of tubes. The experiment was installed in the nursery of the Technology Foundation of the state of Acre in Rio Branco. A completely randomized design with two factors (2 × 3) was adopted, considering two volumes of tubes, 110 cm³ and 180 cm³, and three seedling densities per tray, 1/3, 2/3, and 3/3. After 120 days, it was observed that the seedlings produced in tubes with a volume of 180 cm3 had greater aerial length and stem diameter in relation to the density of seedlings per tray, seedlings produced in less dense trays (1/3) had a higher Dickson quality index. Therefore, it is inferred that seedlings of N. lappaceum are favored when tubes with a volume of 180 cm³ and a density per tray of 1/3 are used.
