Nitrogen and molybdenum fertilization and inoculation of common bean with Rhizobium spp. in two oxisols 1
Figueiredo, Marislaine Alves de; Oliveira, Dâmiany Pádua; Soares, Bruno Lima; Morais, Augusto Ramalho de; Moreira, Fatima Maria de Souza; Andrade, Messias José Bastos de.
The aim of this study was to evaluate the effects of foliar application of molybdenum and small dose of nitrogen at planting on common bean production when using seed inoculation with rhizobia. Two field experiments were conducted, applying a randomized block design and a factorial arrangement (3x2x2) + 1, with three replicates. Treatments consisted of inoculation with Rhizobium spp. (strain CIAT 899T, strain UFLA 02–100, and uninoculated), foliar application of molybdenum (0 and 80 g ha-1), and fertilization with N-urea at planting (0 and 20 kg ha-1), with an additional N treatment of 40 applied at planting and 40 kg ha-1 applied as topdressing. The foliar application of molybdenum did not favor the nodulation, but its effect on yield was dependent on the...

Symbiosis of rhizobia with Gliricidia sepium and Clitoria fairchildiana in an Oxisol in the pre-Amazon region of Maranhão State 1
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...
