RESUMOO objetivo do estudo foi avaliar o efeito da vermicompostagem de resíduos de carne e esterco bovino no desenvolvimento de mudas de eucalipto e pinus. O experimento foi conduzido em delineamento inteiramente casualizado com oito tratamentos, sendo quatro elaborados a partir da adição de 0%, 20%, 40% e 60% de esterco bovino ao resíduo de carne, ambos vermicompostados, e quatro constituídos pela adição de 0%, 20%, 40% e 60% de vermicomposto ao substrato comercial, com sete repetições. Foram avaliados a altura das mudas, o diâmetro do colo, a massa seca da parte aérea e radicular, a área superficial específica, o índice de qualidade de Dickson e a relação entre a altura da muda e o diâmetro do colo. A adição ao substrato comercial de 20% e 40% de vermicomposto proporciona desenvolvimento e qualidade de mudas de eucalipto equivalentes ao alcançado com a utilização de 100% de substrato comercial. As mudas de pinus não são favorecidas pelas proporções de vermicomposto testadas.Palavras-chave: esterco bovino, resíduo orgânico, espécies florestais, Eucalyptus grandis, Pinus elliottii. Influence of Different Concentrations of Vermicompost in the Development of Eucalyptus and Pine Seedlings ABSTRACTThe objective of this study was to evaluate the effect of meat waste and cattle manure vermicomposting in the development of eucalyptus and Pinus seedlings. The experiment was conducted in a completely randomized design with eight treatments with seven repetitions. The treatments were: 0%, 20%, 40% and 60% of cattle manure added to meat waste, both vermicomposted, and 0%, 20%, 40% and 60% of the vermicompost added to commercial substrate. Stem height and diameter, shoot and root dry mass, specific surface area, Dickson quality index and the ratio between stem height and diameter were assessed. Addition of 20% and 40% of vermicompost in eucalyptus seedling cultivation promotes similar development and quality obtained with addition of 100% of commercial substrate. Pinus seedlings are not influenced by the proportions of vermicompost tested.

“…Potassium is a nutrient that does not participate in organic combinations and participates instead in the structural function, which causes it to be readily released when organic fertilizers are used (Kiehl, 2010;Magro et al, 2010). Antunes et al (2016) evaluated the height of the seedlings in black acacia (Acacia mearnsii) and observed that the best value in this variable was obtained in the substrate with the application of vermicompost with the mixture of bovine manure and food residues, whose value was 22.6% superior to the control treatment. The superiority of the values observed in the stem diameter for the pitomba seedlings in the substrate with the fruit and vegetable residue compound can be explained by the high phosphorus, potassium, calcium, and magnesium contents present in this substrate in relation to the other substrates evaluated, as shown in Table 1.…”

“…The values observed for the nitrogen contents are higher than those of the other plant species studied, as described by Barros et al (2013), who worked with different organic substrates in yellow passion fruit seedlings (Passiflora edulis Sims f. Flavicarpa Degene) and showed that the nitrogen accumulation was better in the substrate composed of soil and tanned bovine manure. Reis et al (2015) obtained a value of 16.79 g kg -1 working with Dilodendron bipinnatum Radkl (Sapindaceae); whereas Antunes et al (2016) found values varying between 9.73 and 12.44 g kg -1 using vermicompostos of different agroindustrial residues in black acacia (Acacia mearnsii Wild). The same authors have reported that the concentration of nutrients may be an indication of nutrition because of the different types of nutrient source applied.…”

“…Aside from being an important enzymatic activator, it exerts a fundamental physiological function on plants, which is the regulation of stomatal closure and opening (Prado, 2008). Antunes et al (2016) used different agroindustrial residues as substrate in the initial growth of Acacia mearnsii, the accumulated potassium contents in the dry matter of the leaves of the seedlings ranging from 6.41 to 13.79 g kg -1…”

“…With the increase in the production of seedlings throughout the national territory, it is necessary to use these residues as a substrate for initial plant growth, avoiding contamination of soil and groundwater when discarded in the environment. According to Antunes et al (2016), although the addition of conventional fertilizers contribute to soil fertility and rapid availability to plants, the use of organic fertilization improves soil biotic conditions, thereby promoting plant growth.…”

The pitombeira (Tasilia esculenta Radlk.) is a fruit native to Brazil, which is being exploited in an extractive way. To get agronomic information, such as the formation of mudase to be used in future commercial plantations, therefore, the objective was to evaluate the initial development and accumulation of nutrients in pitombeira seedlings submitted to different organic substrates and biofertilizer application in the soil. The experimental design was in randomized blocks, with a factorial arrangement of 4 × 2 and five replications. The treatments corresponded to four substrates (W, control; CS, commercial substrate; RFV, composite of fruit and vegetable remnants of a university restaurant; SIP, residues of industrialized products) in the substrate without and with Supermagro biofertilizer. Ninety days after sowing, the plant height, stem diameter, total dry mass, Dickson Quality Index, and leaf content in macronutrients were evaluated. The use of residues of fruits and vegetables (RFV) and residues of industrialized products (SIP) is recommended for the composition of submetry of pitombeira because these contribute to the greater growth of pitombeira seedlings. The addition of organic residues increases the quality of pitombeira seedlings having higher quality as biofertilizer treatments. Commercial substrate (CS) increases nitrogen and potassium terrors for substrates with fruit and vegetable residues (RFV), and the residues of industrialized products (RPI) used for the propagation of pitombeira seedlings can be recommended for the production of seedlings, because they increase the leaf content of phosphorus, calcium, magnesium, and sulfur.

This work aimed to evaluate the development of seedlings by cuttings Brazilian peppertree cuttings submitted to different treatments and substrates. For that we used a randomized experimental design in a 2x4 factorial scheme, consisting of the use (3.000 mg.L-1)) or not of IBA associated with different types of substrate: vermiculite (V); carbonized rice husk with vermicompost (CV); carbonized rice husk with vermicompost and sand (CVS); Turfa Fértil® commercial substrate (CS), in four replicates per treatment, each consisting of 10 cuttings. After 90 days, the following variables were evaluated: percentage of rooted cuttings, length of the largest root, number of leaves over 1 cm in length, and dry root weight. The Generalized Linear Model (GLM) was used with p ‹ 0.05 of significance in the data analysis. The use of IBA in rooting Brazilian peppertree cuttings is recommended. CVS is the substrate with the best interactions, and substrates like CS should be avoided.
