Perspectives for Biochar as a vehicle for inoculation of phosphate solubilizing...
França, Rafaela Felix da; Medeiros, Erika Valente de; Silva, Renata Oliveira; Fausto, Ronaldo Anderson da Silva; Souza, Carlos Alberto Fragoso dePhosphorus (P) plays a vital role in many aspects of plant growth and development. The low amount of available P in agricultural soils reduces crop productivity and phosphate fertilizers are often applied. However, due to the high affinity of P for the soil constituents, the availability of this element becomes limited to plants. Thus, alternative, ecological, and low-cost techniques have been studied to improv...
Adolescents knowledge about contraceptives in a public school in the interior o...
Cavalcante, Jéssica Maria Fragoso; Cavalcante, José Luis Guilherme Fragoso; Soares, Jullyana Maria Martins da Silva; Souza, Carlos Alberto Fragoso deContraceptive methods or contraceptives are all resources used by men and women to prevent pregnancy and sexually transmitted diseases. One of the main contraceptive methods of worldwide diffusion are the oral hormonal contraceptives, known as birth control pills, these have been widely used by the female population. In addition to the contraceptive action, this class of drugs has other therapeutic purposes suc...
Plant extract as a strategy for the management of seed pathogens: a critical re...
Almeida, Abraão Rodrigues de; Silva , Isabel Correia da; Souza, Carlos Alberto Fragoso de; Avelino, João Raphael LimaAbstract Seeds associated to fungal pathogens are efficient vehicles for disease dissemination in the field. Such pathogens affect the seed quality and longevity, causing a decrease or loss of germination, discoloration, necrosis, and decay, in addition to leading to the production of mycotoxins in some pathosystems. To control them several synthetic chemicals are used. Nevertheless, the use of synthetic chemic...
Biochar and Trichoderma spp. in management of plant diseases caused by soilborn...
Medeiros, Erika Valente de; Silva , Lucas Figueira da; Silva, Jenifer Sthephanie Araújo da; Costa , Diogo Paes da; Souza, Carlos Alberto Fragoso deA better understanding of the use of biochar with Trichoderma spp. (TRI), considered the most studied tool for biological control, would increase our ability to set priorities. However, no studies exist using the two inputs on plant disease management. Here, we hypothesized that biochar and TRI would be used for the management of soilborne plant pathogens, mainly due to changes in soil properties and its intera...
Microbial biomass and enzymatic activities in sandy soil cultivated with lettuc...
Martins Filho, Argemiro Pereira; Santos, Ivonaldo Carlos da Silva; Lima, Leandro Dias de; Andrade, Dayane da Silva de; Medeiros, Erika Valente deOs micro-organismos promotores do crescimento de plantas vêm sendo estudados como uma importante ferramenta para o aumento da produção agrícola. Lactuca sativa (alface) é a hortaliça folhosa mais consumida em todo mundo. Inúmeros micro-organismos podem atuar de forma benéfica no crescimento desta cultura. O objetivo do presente trabalho foi avaliar a eficácia de isolados de Trichoderma e Pseudomonas sp. na biom...
Soil microbiological activity and productivity of maize fodder with legumes and...
Martins Filho, Argemiro Pereira; Moura, Mácio Farias de; Araújo, Maysa Bezerra de; Santana, Marthony Dornelas; Medeiros, Erika Valente deO milho é um importante cereal muito utilizado no mundo, tanto como alimentação para humanos como para animais. O nitrogênio (N) é um nutriente requerido em grande quantidade pelo milho, e os solos são limitantes em atender essa necessidade. As leguminosas nodulantes podem ser utilizadas como fonte de Nitrogênio, por formarem associações simbióticas com bactérias capazes de fixar N atmosférico, outra importante...
Extracellular serine proteases by Acremonium sp. L1-4B isolated from Antarctica...
Evaristo da Silva Nascimento, Talita Camila; Sena, Amanda Reges de; Galindo Gomes, Jose Erick [UNESP]; Santos, Wellington Leal dosMade available in DSpace on 2018-11-27T08:16:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-10-01; Acremonium sp. L1-4B isolated from lichen in Antarctica was used to produce extracellular proteases through submerged fermentation using cactus pear extract (Opuntia ficus-indica Mill.). A 2(3) factorial design was applied to optimize the protease production using three independent variables, namely tem...
TRIPLE SUPERPHOSPHATE IN THE INITIAL GROWTH OF SUGAR APPLE ROOTSTOCKS (Annona s...
Dantas, Django Jesus; Mendonça, Vander; Medeiros, Erika Valente de; Góes, Glêidson Bezerra de; Dantas, Débora Jesus- O objetivo deste trabalho foi avaliar o efeito de doses de superfosfato triplo no desenvolvimento de portaenxerto de pinheira. O delineamento experimental utilizado foi em blocos casualizados com cinco doses de superfosfato triplo (0; 2,5; 5,0; 7,5 e 10,0 kg m-3 de substrato), quatro repetições e seis plantas por parcela. As variáveis analisadas foram: altura da muda (cm), comprimento da raiz (cm), número de ...
Morphological diversity of rhizobia from cowpea cultivated in Rio Grande do Nor...
Medeiros, Erika Valente de; Martins, Claudia Miranda; Lima, José Arcanjo Melo; Fernandes, Ykesaky Terson Dantas; Oliveira, Vianney Reinaldo deAs a result of it nutritional and rustic characteristics, cowpea has become an important source protein in the Northeast region of Brazil. Cowpea may benefit from biological nitrogen fixation and can receive part of the nitrogen needed for culture from symbiosis, which reduces the cost of production. An experiment in greenhouse conditions was carried out in order to assess the diversity of rhizobia isolates of ...
