“…For root length (RL), it was verified that SB1, SB2, and SB3 did not differ statistically, but were numerically superior to SB4 (Figure 7). According to Lima et al (2013), this effect may result from the reduction of soil volume according to the volume of biochar, which decreases the amount of nutrients available, since biochar results from the pyrolysis of wood of different tree species and can act on the retention and not on the availability of nutrients. Figure 8 shows that in SB3 and SB4 the number of leaves was statistically higher in the environment under 50% shade compared to that under full sun.…”

ABSTRACT The objective of this study was to evaluate the production of watermelon seedlings irrigated with saline waters and cultivated in different types of environments and substrates. The experimental design was completely randomized with split-split plots, in which the plot corresponded to two growing environments (EN1 = full sun and EN2 = 50% shade black net), the subplot to two types of irrigation water (IW1 = 0.8 and IW2 = 2.5 dS m-1) and the sub-subplot to four types of substrates (SB1 = vermiculite + coconut fiber, SB2 = manure + soil, SB3 = carbonized rice husk + soil, SB4 = biochar + soil), with four replicates of twenty-five seeds. The variables analyzed were: emergence percentage (EP), emergence speed index (ESI), mean time of emergence (MTE), number of leaves (NL), stem diameter (SD), seedling height (SH) and root length (RL), shoot dry mass (SDM), root dry mass (RDM) and total dry mass (TDM). The EN2 treatment provided better conditions for emergence and initial growth, and EN1 was also favorable to the emergence and initial growth of watermelon seedlings, when the substrates SB1 and SB2 were used.

“…Estudos mostram o potencial de uso do biocarvão como condicionador de solo (Gómez-Luna et al, 2012;Drake et al, 2015;Fernández-Ugalde et al, 2017;Gao et al, 2017;Lin et al, 2017;Zhang et al, 2017;Ramlow et al, 2018;Zhang et al, 2019;Maia et al, 2021) e de substrato (Cavalcante et al, 2012;Marimon et al, 2012;Petter et al, 2012a;Petter et al, 2012b;Lima et al, 2013a;Lima et al, 2013b;Rezende et al, 2016;Basílio et al, 2020).

A prática de misturar ou combinar substratos de diferentes origens é comum nos viveiros, sendo o uso de biocarvões um meio para melhorar a composição do substrato, atender as particularidades de cada planta, reduzir custos de produção, e ressignificar materiais que antes seriam descartados no ambiente. Nesse sentido, este trabalho objetivou verificar a influência do uso de biocarvão na produção de mudas de espécies lenhosas, de forma a elucidar doses e composições de substratos que melhor se ajustam à produção de mudas de qualidade. Por meio de uma revisão de literatura dos últimos dez anos, buscou-se verificar as doses recomendadas e os efeitos do biocarvão na composição de substratos. Na literatura, verificou-se o potencial de uso do biocarvão como componente de substrato, principalmente por apresentar estrutura porosa e reativa, capaz de aumentar a disponibilidade de água e outros nutrientes para a planta e abrigar diversos microrganismos benéficos. A dose adequada de biocarvão no substrato pode variar de acordo com a espécie de interesse, sistema de manejo, fonte e proporções de insumos. Dessa forma, conclui-se que diferentes fontes de insumos, combinações e proporções entre eles afetam de forma variada a produção de mudas, sendo a melhor dose de biocarvão no substrato um assunto complexo e de notária importância quando o objetivo é produzir mudas com qualidade.

“…In fact, its capacity of being highly stable in soil contribute to improvements in chemical, physical and biological soil properties (Trazzi et al, 2016;Petter & Madari, 2012). As a result, biochar can improve soil commercial substrates and contribute to reduction of chemical fertilizers uses, being a sustainable and low-cost alternative to increase seedlings quality (Lima et al, 2013).…”

Moringa oleifera is an allogamous plant that is propagated by seeds and cuttings, rich in vitamin A and C, phosphorus, calcium and proteins. However, its best propagation form for the large-scale production is still unknown, as well the most suitable substrate for seedling production. Production of forest species seedlings with a high quality is directly related to physical and chemical substrates properties. Using biochar as substrate for seedlings production is an economical and sustainable solution for this proposal. The aim of this study was to evaluate the influence of three biochar types, in two concentrations, for production of Moringa oleifera seedlings. Three types of substrates were formulated using residues of dry coconut shells, sewage sludge and orange bagasse. The experiment was carried out in a greenhouse, installed in a completely randomized design, consisting of seven treatments (substrates formulated with biochar in two doses, 1 and 2%) and the control, with four replicates, totalizing 28 seedlings. One month after sowing, the seedlings were evaluated biweekly for 60 days in relation to stem base diameter, shoot heigh, leaves number, shoot dry matter, root dry matter, total seedling dry matter and Dickson Quality Index. The substrate formulated using sewage sludge biochar at 2% provided a greater increasing in shoot dry matter. This concentration improved seedling height and stem base diameter in 10.5 and 0.83 mm, respectively, compared to the control. In general, biochar improved physical and chemical soil quality, promoting a better M. oleifera seedlings development.
