1. Sugarcane inoculated with endophytic diazotrophic bacteria: effects on yield, biological nitrogen fixation and industrial characteristics
Abstract: The growing need for the use of clean energy has led society to seek alternatives to fossil fuels in order to less pollute the environment. Sugarcane has been known to produce enough biomass and to have associative microorganisms, such as plant growth-promoting bacteria (PGPB), which have the potential to improve the yield of crops. The objective

2. Physiological and N2-fixation-related traits for tolerance to drought in soybean progenies
Resumo: O objetivo deste trabalho foi avaliar seis genótipos de soja (Glycine max) quanto aos parâmetros fisiológicos e à fixação biológica de nitrogênio, em condições de restrição hídrica, e sua capacidade de recuperação após reidratação, com base em componentes de produção. Os genótipos avaliados em casa de vegetação foram os seguint

3. Genetic linkage map and mapping of the locus of biological nitrogen fixation inefficiency in cowpea
ABSTRACT. The objectives of the present study were to construct a cowpea genetic map using the F2 population resulting from the cross IC-1 x BRS Marataoã, based on single nucleotide polymorphism (SNP) markers, and to map the cpi gene, with additional reference to introgression with the consensus map of species, aiming to identify markers for assisted select

4. Forage production and quality of tropical forage legumes submitted to shading
RESUMO: Encontrar espécies tolerantes ao sombreamento é essencial para o sucesso dos sistemas silvipastoris, cada vez mais frequentes nos últimos anos. Em se tratando de leguminosas, que possuem potencial de fixação biológica de nitrogênio, há uma grande carência de conhecimento em ambientes sombreados. Objetivou-se avaliar o cultivo de quatro legu

5. Enrichment, quality, and productivity of soybean seeds with cobalt and molybdenum applications
Resumo: Cobalto (Co) e molibdênio (Mo) são nutrientes indispensáveis para a fixação biológica e assimilação de nitrogênio pela soja. Neste trabalho teve-se como objetivo avaliar o aumento do Co e Mo nas sementes de soja pela aplicação via foliar desses nutrientes na planta mãe. O experimento foi realizado em lavoura de produção de sementes, em

6. Role of Rhizobia in Suppressing the Root Diseases of Soybean Under Soil Amendment
RESUMO: Os rizóbios são bactérias que vivem no solo, caracterizadas pela capacidade única de colonizar as raízes das culturas de leguminosas, onde formam nódulos de fixação de nitrogênio. Foram acumuladas diversas evidências com o objetivo de identificar os benefícios associados ao uso de rizóbios como agentes de controle biológico contra patóg

7. New rhizobia strains isolated from the Amazon region fix atmospheric nitrogen in symbiosis with cowpea and increase its yield
ABSTRACT Studies in the Amazon indicate a wide diversity of rhizobia with the ability for biological nitrogen fixation (BNF), which could expand the number of strains approved for cowpea. Thus, the aim of this field study was to evaluate the agronomic performance in cowpea of the several strains isolated from the soils of the Brazilian states Acre and Rondô

8. Inoculation with Azospirillum brasilense on corn yield and yield components in an integrated crop-livestock system
ABSTRACT. Inoculation of corn with diazotrophic bacteria reduces the need for nitrogen fertilization and mitigates environmental contamination risks due to the bacteria’s biological nitrogen-fixation capacity. The aim of the present study was to evaluate the effect of corn seed inoculation with Azospirillum brasilense under different nitrogen levels and p

9. Forage sorghum-legumes intercropping: effect on growth, yields, nutritional quality and economic returns
ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip int

10. Antioxidant response of cowpea co-inoculated with plant growth-promoting bacteria under salt stress
Abstract Soil salinity is an important abiotic stress worldwide, and salt-induced oxidative stress can have detrimental effects on the biological nitrogen fixation. We hypothesized that co-inoculation of cowpea plants with Bradyrhizobium and plant growth-promoting bacteria would minimize the deleterious effects of salt stress via the induction of enzymatic a

11. Water restriction and physiological traits in soybean genotypes contrasting for nitrogen fixation drought tolerance
ABSTRACT Biological nitrogen fixation (BNF) is essential to the economic viability of the soybean [Glycine max (L.) Merrill] crop in Brazil, but drought may impair the BNF processes. We evaluated physiological traits of nitrogen fixation drought-tolerant (NFDT) (R01-581F, R01-416F and R02-1325) and drought-susceptible (CD 215 and BRS 317) genotypes of soybea

12. New Native Rhizobia Strains for Inoculation of Common Bean in the Brazilian Savanna
ABSTRACT Maximization of biological nitrogen fixation in the common bean (Phaseolus vulgaris L.) crop depends on the genetic characteristics related to the plant, the symbiotic efficiency of rhizobia, and environmental factors. The objective of this study was to evaluate the performance of rhizobia selected beforehand from Cerrado (Brazilian tropical savanna
