“…Com isso, constatou-se que os melhores resultados foram obtidos com as maiores proporções do caule decomposto de babaçu até 80% da composição do substrato. Segundo Cordeiro et al (2018), o CDB é rico em macronutrientes como nitrogênio, fósforo, potássio e cálcio, possibilitando uma maior nutrição da planta em substratos com maior concentração desse material, exceto para concentrações puras (100% CDB).

A propagação vegetativa de floríferas por estaquia é uma alternativa viável para a produção em larga escala, e quando associado a substratos regionais, essa alternativa possibilita obter mudas que atendam às exigências do mercado consumidor, além de reduzir o custo de produção. Buscou-se avaliar com a pesquisa, proporções crescentes de caule decomposto de babaçu (CDB), acrescida de casca de arroz carbonizada (CAC) na propagação vegetativa de Polyscias guilfoylei. O experimento foi conduzido em casa de vegetação com 70 % de interceptação luminosa entre os meses de agosto a outubro de 2019. Foi utilizado o delineamento inteiramente casualizado, com seis tratamentos nas seguintes proporções: 100% de CAC; 20% de CDB + 80% de CAC; 40% de CDB + 60% de CAC; 60% de CDB + 40% de CAC; 80 % de CDB + 20 % de CAC; 100 % de CDB. As variáveis foram: número de folhas; área foliar; número de brotações; altura da brotação; diâmetro da brotação; comprimento da raiz; volume da raiz; massa fresca da parte aérea; massa fresca da raiz; massa seca da parte aérea; massa seca da raiz; diâmetro das estacas; percentual de sobrevivência e índice de qualidade de Dickson. Após 60 dias verificou-se que não é interessante produzir mudas de P. guilfoylei nas proporções de 100% de CAC e 100% de CDB. No entanto, as estaquias de Polyscias guilfoylei responderam positivamente quando utilizado as proporções de 60% de CDB + 40% de CAC e 80% de CDB + 20% de CAC, sendo estas proporções recomendadas.

“…The use of commercial substrates that are based on expanded vermiculite and organic materials [13] is costly [7,14], however, decomposed organic residues and fractions from Brazilian pre-Amazonian palms, such as babassu (Attalea speciosa Mart. ), buriti (Mauritia vinifera Mart.…”

“…), and carnauba (Copernicia prunifera Mill. ), can reduce production costs without compromising seedling quality [14,15,16,17,18]. The aim of this study was to investigate three dormancy breaking methods (namely, mechanical scarification, immersion in water, and chemical scarification) and different substrates for S. tubulosa seedling production.…”

“…One of the main aspects related to quality and profitability in the cultivation of vegetables resides in the type of substrate used (Cordeiro et al, 2018), as it may interfere with the germination, formation and development of the crops (Pelizza et al, 2016). Therefore, due to the importance of the lettuce culture and the influence that the substrate provides in the final results, the objective of this research was to determine the efficiency of different substratum formulations for the commercial development of butter-head cultivar, through sensory analysis.…”

Regional residues of agricultural, livestock and forestry activities can be used in the formulation of substrates that allow the adequate supply of nutrients in family agricultural production. The objective of this research was to determine the efficiency of different formulations of substrates enriched with babassu biochar for the commercial development of lettuce through sensorial analysis. The experiment was conducted in the period from November 2016 to February 2017. The design was completely randomized, with nine treatments and 15 replicates. Dystrophic Yellow Latosol (dYL), increasing doses of biochar (B); organic fertilizer (OF) and mineral fertilizer (MF) were used in the substrate preparation. The treatments evaluated were: S1 = dYL, S2 = dYL +10 t ha-1B, S3 = dYL +20 t ha-1B, S4 = dYL 30 t ha-1 B, S5 = dYL + 2 t ha-1 OF, S6 = dYL + 5 t ha-1 OF, S7 = dYL +8 t ha-1 OF, S8 = dYL +10 t ha-1 B + 2 t ha-1 OF, S9 = dYL + MF. At 80 days after sowing, sensory analyzes were carried out in order to judge the visual characteristics of the lettuce per treatment. Based on the multicriteria analysis the S4 substrate, the one that contain 30 t ha-1 of biochar proved to be the most successful substrate to comply with the study variables. Thus, the use of biochar can be considered as a viable alternative to mineral fertilizer in terms of sensory analysis.
