Evolution of nutrient availability in maturation phase of composting using proportions of different residues inoculated with Beijerinckia indica Agronomy
Sousa, Lusiene Barbosa; Stamford, Newton Pereira; Oliveira, Wagner Silva; Silva, Emmanuella Vila Nova; Martins, Marllon dos Santos; Santos, Carolina Etienne Rosália e Silva.
Organic matter has low N content; however, organic matter may be enriched by inoculation with selected diazotrophic bacteria. The aim of the paper was to evaluate the effects of biofertilizer produced by mixing different types and proportions of organic matter inoculated with the diazotrophic bacteria Beijerinckia indica. The experiment consisted of plastic trays (6 L) containing 5 kg of three different types of organic matter (filter mud cake, earthworm compost, and crop residue) applied in the following proportions (v:v:v): 1-(5:0:0), 2-(4:1:0), 3-(4:0:1), 4-(3:2:0), 5-(3:1:1), 6-(3:0:2), 7-(2:3:0), 8-(2:2:1), 9-(2:1:2), 10-(2:0:3), 11-(1:4:0), 12-(1:3:1), 13-(1:2:2), 14-(1:1:3), 15-(1:0:4), 16-(0:5:0), 17-(0:4:1), 18-(0:1:4), 19-(0:3:2), 20-(0:2:3), and...

Symbiosis of rhizobia with Gliricidia sepium and Clitoria fairchildiana in an Oxisol in the pre-Amazon region of Maranhão State Agronomy
Coelho, Katia Pereira; Ribeiro, Paula Rose de Almeida; Moura, Emanoel Gomes de; Aguiar, Alana das Chagas Ferreira; Rodrigues, Tainara Louzada; Moreira, Fatima Maria de Souza.
 Gliricidia (Gliricidia sepium) and sombreiro (Clitoria fairchildiana) have been recommended for agroforestry systems and reforestation of degraded areas due to their fast growth and symbiosis with rhizobia. However, little is known about native populations that nodulate these species. The objective of this study was to evaluate the phenotypic and genetic diversity of nitrogen-fixing bacteria isolated from nodules of gliricidia and sombreiro in alley cropping systems located in the pre-Amazon region of Maranhão State and to confirm their nodulation ability. Nodules were field collected from 20 plants of each species. The isolated strains were characterized morphologically, their 16S rRNA gene was partially sequenced, and their symbiotic ability was...

Compatibility among fungicide treatments on soybean seeds through film coating and inoculation with Bradyrhizobium strains - doi: 10.4025/actasciagron.v32i4.5756 Agronomy
Pereira, Carlos Eduardo; Universidade Estadual de Santa Cruz; Moreira, Fátima Maria de Souza; Universidade Federal de Lavras; Oliveira, João Almir; Universidade Federal de Lavras; Caldeira, Carla Massimo; Universidade Federal de Lavras.
This research evaluated the development of soybean plants grown in a greenhouse, from seeds that were treated with fungicide, film coated and inoculated with Bradyrhizobium. Seeds from the soybean cultivar ‘Vencedora’ were submitted to treatments disposed in a factorial 5 x 3 x 2 design. The seeds were treated with Derosal Plus® with polymer; Tegran® with polymer; Derosal Plus® without polymer, Tegran® without polymer; and without fungicide and without polymer. After the chemical treatment, the seeds were inoculated with peat or liquid inoculants, and without inoculant. The chemical treatments were used either previous to or after the six months of storage. Seed inoculation was performed with CPAC15 and BR29 strains,...
