Influência De Diferentes Fontes De Matéria Orgânica Na Propagação Da Schinus Terebinthifolius Raddi

Abstract

Resumo -A recuperação de ecossistemas degradados pode não ocorrer da maneira desejada se houver carência nutricional ou suprimento insuficiente de nutrientes durante o estádio inicial de desenvolvimento. Portanto, o uso da matéria orgânica se torna essencial nesta etapa inicial de desenvolvimento. O objetivo desse trabalho foi avaliar o desenvolvimento e a qualidade de mudas de aroeira-vermelha em função de substratos contendo diferentes fontes de matéria orgânica. O experimento foi realizado em casa de vegetação utilizando sete fontes de matéria orgânica para a composição do substrato: lodo de curtume, resíduo de torrefação de café, esterco bovino curtido, resíduo de laticínio e composto de lixo urbano, além dos tratamentos sem uso de matéria orgânica (solo com e sem adubação) As fontes de matéria orgânica foram adicionadas ao solo, para a composição do substrato, na proporção de 20%. Foram avaliadas características de desenvolvimento e de qualidade das mudas, observando-se que todas as fontes de matéria orgânica utilizadas favoreceram o desenvolvimento das mudas de aroeira-vermelha em relação às mudas que não receberam matéria orgânica. A mistura solo com composto urbano e esterco bovino mostrou-se superior na maioria das características avaliadas produzindo mudas de melhor qualidade.Palavras-chave -aroeira-vermelha, substrato alternativo, sustentabilidade, reflorestamento.Abstract -Recovery of degraded ecosystems may not occur in the desired way if there is nutritional deficiency or insufficient nutrient supply during the early stage of development. Therefore, the use of organic matter becomes essential at this early stage of development. The objective of this work was to evaluate the development and the quality of seedlings of aroeira-red as a function of substrates containing different sources of organic matter. The experiment was carried out in a greenhouse using sevensources of organic matter for the substrate composition: tannery sludge, coffee roasting residue, tanned bovine manure, dairy residue and urban waste compost, as well as treatments without the use of matter Organic matter (soil with and without fertilization) The sources of organic matter were added to the soil, for the composition of the substrate, in the proportion of 20%. Developmental and quality characteristics of the seedlings were evaluated, observing that all the sources of organic matter favored the development of the red-apple seedlings in relation to the seedlings that did not receive organic matter. The mixture with urban compost and bovine manure showed to be superior in the majority of evaluated characteristics producing seedlings of better quality.

Tannery Sludge Added in Commercial Substrate for Capsicum baccatum Pepper Seedlings Production

“…In relation to the leaf area ( Figure 1A), the estimated value obtained with the addition of 80% of tannery sludge in the substrate was 2.5 cm². The leaf area is a fundamental component for plants, since the larger is the leaf area, the greater the light uptake by the plant and the greater the production of metabolic energy, which will be responsible for the maintenance of plant metabolism and growth, as well as in determining the productivity of the plant (Koester et al, 2014;Sales et al, 2017). Sales et al (2018c) studying chlorophyll content in Schinus terebinthifolius Raddi seedlings cultivated in different substrates, showed that the addition of tannery sludge in the substrate positively favors chlorophyll content, as well as other organic materials added in other compounds.…”

“…Sales et al (2018c) studying chlorophyll content in Schinus terebinthifolius Raddi seedlings cultivated in different substrates, showed that the addition of tannery sludge in the substrate positively favors chlorophyll content, as well as other organic materials added in other compounds. The higher organic matter content and nutrients of these substrates may result in higher chlorophyll production and cellular structures, resulting in a larger leaf area (Sales et al, 2017).…”

Rooting of Schinus terebinthifolia Raddi Cuttings as a Function of the Preparation Method and Indolebutyric Acid Concentrations

“…2 established the minimum value for the IQD was 0.20 which is a good indicator of cutting quali general, therefore, in this study, results were found to be higher than the minimum index established by Hunt. Sales et al [25] studied the…”

“…Hunt [24] established the minimum value for the IQD was 0.20 which is a good indicator of cutting quality in general, therefore, in this study, results were found to be higher than the minimum index . [25] studied the effect of different sources of organic matter in the propagation of Schinus terebentifolia where they found IQD values that varied from 0.01 to 0.32 in plants after 121 days.…”
