“…Guajarina and Iaçará the quality of the root system. Use of plant waste or organic compounds on the substrate porosity increases, allowing rapid flow of water, preventing low oxygenation to the roots (Arruda et al, 2007). Possibly the poor drainage in the substrates (c) (27% de AR 100 cm) and (h) (32% de AR 100 cm) coupled with reduced space aeration 6 e 3% (Table 2A), respectively, have contributed to the poor quality of the root system in these substrates (Table 4).…”

The quality of the root system in stem cuttings of Piper nigrum is highly associated with the induction of adventitious roots by means of auxins and type of substrates. The objective of this study was to evaluate the rooting of P. nigrum cv. Bragantina cuttings treated or not with indole-3-butyric acid (IBA) in different substrates. The experiment was conducted in a randomized block design following a factorial 2 x 11 scheme (IBA -0 and 4000 mg kg -1 in talc and 11 substrates), with four repetitions of 16 cuttings each. The auxin increased rooting and improved the quality of the root system. The substrates evaluated presented diverse physical, chemical and microbiological characteristics, interfering significantly in the rooting responses. Substrates (d) -soil + limestone + single superphosphate + potassium chloride + chicken manure and (i) -soil + coffee straw + limestone + single superphosphate are the ones recommended for rooting of pepper cv. Bragantina.

“…Uma alternativa que vem gerando bons resultados, como apresentada no presente estudo é a mistura com outros substratos, condicionando e viabilizando sua utilização (GOMES et al, 2015). Arruda et al (2007) estudando o enraizamento de estacas herbáceas de guaranazeiro em diferentes substratos, concluíram que a mistura de substratos é essencial para o sucesso do enraizamento, sendo que para esse estudo o substrato comercial e o esterco de galinha + carvão proporcionaram maior porcentagem de enraizamento, com 55,9% e 49,3%, respectivamente.…”

Dombeya wallichii, conhecida como astrapéia, é uma planta exótica originária do Madagascar, com características ornamentais e de grande importância para os apicultores, uma vez que sua inflorescência atrai muitas abelhas e seu florescimento se dá no outono e inverno, período crítico de alimento para as mesmas. O presente trabalho teve por objetivo avaliar o uso de substratos na propagação vegetativa de astrapéia por estaquia. A partir de brotações coletadas da base de uma planta matriz localizada no centro de Dois Vizinhos–PR, foram confeccionadas estacas de 10 cm, sem folhas e com corte bisel nas extremidades. O delineamento experimental implantado foi o DIC (Delineamento Inteiramente Casualizado), com três tratamentos, sendo eles substrato orgânico comercial, terra e a mistura entre ambos os substratos na proporção (1:1) (V/V), e quatro repetições de dez estacas por parcela. O plantio foi realizado em tubetes de polipropileno de 120 cm³, contendo os diferentes substratos, que foram acondicionados em bandejas mantidas na casa de sombra do Viveiro Florestal da Universidade Tecnológica Federal do Paraná - Campus Dois Vizinhos. Aos 74 dias, foram avaliadas as variáveis porcentagem de estacas enraizadas, com calos, mortas, vivas, com brotações, número e comprimento médio de raízes. Os dados foram submetidos à análise de variância (P?0,05), utilizando o programa SISVAR 5.6. Para a propagação vegetativa de astrapéia são eficazes, o substrato orgânico comercial e a mistura substrato orgânico e terra caracterizaram-se como os melhores substratos.

“…The mixture of substrates with biochar, aiming to improve soil physicochemical properties, has been studied as a valuable resource that can improve crop yield in tropical infertile and acid soils, and can be used by farmers to increase the productivity of crops of agricultural importance and promote the carbon stock in the soil (Arruda et al, 2007;Maia et al, 2011).…”

Biochar has attracted the attention of the scientific community due to its promising applicability and contribution to the elevation of soil chemical and biological aspects, directly influencing the microbiota, fertility levels and yield of agricultural crops. The objective of this study is to determine the chemical and biological attributes of an acrisol cultivated with beans and submitted to the application of ouricuri biochar. The design was completely randomized in a 4 × 4 factorial scheme, with 4 replications. The factors were the combination of four granulometric bands: G1 (0.42 mm), G2 (0.84 mm), G3 (1.19 mm), G4 (1.68 mm) and four biochar doses (8, 16, 24 and 32 Mg ha -1 ). Then, a control treatment without biochar was added. Morphophysiological aspects of bean culture, and chemical and biological soil indicators were evaluated. Ouricuri biochar promoted improvements in some soil quality indicators. The dose of 32 Mg ha -1 of biochar positively influenced the vegetative development of the plants. The results of this study showed that there is a direct relationship between the particle size and the amount of biochar in the soil. This had a direct effect on the carbon stock of the soil and the microbial population.
