Coffee waste reused as an alternative substrate for the production of Joannesia...
Almeida, Rodolfo Soares de; Nieri, Erick Martins; Monteiro, Eduardo Costa Silva; Silva, Oclízio Medeiros das Chagas; Melo, Lucas Amaral deThe use of agricultural residues as an alternative in the formulation of substrates is a relevant possibility in the production of forest species seedlings, reducing simultaneously the costs and the accumulation of these products in the environment. The objective of this work was to evaluate the potential of substrates composed of coffee production residues for Joannesia princeps Vell. seedlings development. We...
Use of slow-release fertilizers in the forest sector
Cunha, Fernanda Leite; Nieri, Erick Martins; Santos, Juscelina Arcanjo dos; Almeida, Rodolfo Soares de; Melo, Lucas Amaral de; Venturin, NelsonSlow-release fertilizers (SRF) are under development worldwide, and are characterized as intelligent fertilizers, with a high degree of technology employed, capable of releasing nutrients over time to the plant. It reduces the loss of fertilizer by leaching and volatization, increasing the absorption efficiency of the plant. Its use in agriculture has shown satisfactory gains in productivity, with the possibili...
Genetic characterization in the initial growth of progenies of Eremanthus eryth...
Avelar, Maria Lopes Martins; Silva Júnior, Vitor Passos da; Rosado, Lucas Rodrigues; Gonçalves, Flávia Maria Avelar; Pavan, Adriano JoséMacLeish in Aiuruoca, Minas Gerais State, Brazil). Eremanthus erythropappus (DC.) MacLeish is a native species, economically appreciated due to its wood and the extraction of essential oil, whose active ingredient is alphabisabolol, but studies on genetic improvement of this species are still scarce. The aim of this study was to evaluate survival, genetic variability and estimate genetic parameters in E. erythr...
Growth and seedlings quality of Handroanthus heptaphyllus with cattle manure in...
Lisboa, Alysson Canabrava; Melo Júnior, Cícero José Azevedo Homem de; Alves Tavares, Fernanda Paula; Almeida, Rodrigo Braga de; Melo, Lucas Amaral deThe objective of this work was to verify the influence of different proportions of bovine manure on substrate composition for Handroanthus heptaphyllus growth and seedlings quality. Five different ratios of bovine manure in the substrate composition were evaluatedin the following proportions: 0, 15, 30, 45 and 60%. We verified that H. heptaphyllus seedlings responded positively to bovine manure inproportions of...
Otimização do tempo necessário para o enraizamento de miniestacas de clones híb...
Melo, Lucas Amaral de; Xavier, Aloísio; Paiva, Haroldo Nogueira de; Borges, Silvano RodriguesCada uma das fases do processo de miniestaquia é essencial para o sucesso da produção de mudas. O presente estudo teve como objetivo avaliar o tempo para o enraizamento em miniestacas de cinco clones híbridos de Eucalyptus grandis e ajustar modelos que melhor expressem o comportamento dos materiais genéticos durante o processo rizogênico. O processo de enraizamento das miniestacas foi conduzido em casa de veget...
Richness of native forest species seedlings potentially produced in Rio Grande ...
Oliveira, Carlos Delano Cardoso de; Gonzaga, Luciana de Moura; Carvalho, Josina Aparecida de; Melo, Lucas Amaral de; Davide, Antônio ClaudioEcological restoration plays a fundamental role in ecosystem integrity recovery from restoration of species richness and structure of plant communities. Thus, if the decision is for planting, the production of forest seedlings with high species richness subsidizes the success of this practice. The aim of this study was to analyze the richness of native tree species potentially produced in nurseries in Rio Grand...
Vegetative propagation of Bambusa vulgaris
Braga, Rafael Malfitano; Santos, Karina Rodrigues; Molina, Raul Alberto Rico; Nieri, Erick Martins; Melo, Lucas Amaral deBamboo is an important source of raw material of multiple uses. The development of simple techniques for its propagation is a practical way to enable its implementation in ownership of low technology. The present work had the objective of evaluating artisanal propagation methods for Bambusa vulgaris. Two types of propagules were tested, with buds budded or not, and three relative positions to the removal of veg...
Enraizamento de miniestacas de clones híbridos de Eucalyptus globulus
Borges, Silvano Rodrigues; Xavier, Aloisio; Oliveira, Leandro Silva de; Melo, Lucas Amaral de; Rosado, Antônio MarcosEste estudo teve como objetivo avaliar o efeito do regulador de crescimento ácido indolbutírico (AIB) no enraizamento de miniestacas apicais e intermediárias de clones de Eucalyptus urophylla x E. globulus e Eucalyptus grandis x E. globulus. O enraizamento das miniestacas foi conduzido durante 30 dias em casa de vegetação climatizada e, em seguida, as mudas foram transferidas para casa de sombra, permanecendo p...
EFFECT OF THE DISPOSITION OF CATTLE REARING RFFLUENTS IN THE SOIL AND PLANT BIO...
Teixeira, Francisco Osvaldo Prado; Botelho, Soraya Alvarenga; Melo, Lucas Amaral de; Fia, Ronaldo; Teixeira, Gabriel Arcocha PradoThe objective of this study was to determine the characteristics of percolate in different soil depths derived from the application of livestock wastewater (LWW), and assess the growth of Brachiaria pasture by analysis of forage plant mass. The pH values of percolate ranged from 5.2 to 7.0, without showing any tendency of increasing or decreasing in function of depth. The result of the chemical oxygen demand (C...
Armazenamento, aplicação de antioxidantes e otimização do tempo em casa de vege...
Melo, Lucas Amaral deConselho Nacional de Desenvolvimento Científico e Tecnológico; The present study aimed to determine the time for the rooting of minicuttings in a climatized greenhouse; to assess the influence of the time interval between collection/preparation and plantation, and; to evaluate the use of antioxidants in minicutting rooting of Eucalyptus clones. Minicuttings of five Eucalyptus spp. clones (C1, C2, C3 and C4 = Eu...
