“…There was no significant variation in nodulation and shoot dry matter production of the inoculated and non-inoculated treatments, which did not differ from the controls that were fertilized or not fertilized with mineral N (Table 3), which has also been observed in other studies (Fonseca et al 2013;Figueiredo et al 2016;Oliveira et al 2016). Fertilization with 40 kg ha -1 of N-urea at planting did not affect nodulation because the low application rate was insufficient to suppress nodulation, as also indicated by Figueiredo et al (2016).…”

“…Fertilization with 40 kg ha -1 of N-urea at planting did not affect nodulation because the low application rate was insufficient to suppress nodulation, as also indicated by Figueiredo et al (2016). Another possible explanation for this occurrence is that high rainfall, in the order of 300 mm, leached part of the mineral N and stimulated nodulation of the plant in response to the nutritional deficiency induced (Moreira and Siqueira 2006;Figueiredo et al 2016).…”

“…PALAVRAS CHAVE: Phaseolus vulgaris L., rizóbio, fixação biológica de nitrogênio, inoculação na semente Agronomic efficiency of Rhizobium strains from the Amazon region in common bean ACTA AMAZONICA Common bean is a legume capable of biological nitrogen fixation (BNF) through symbiosis with bacteria that fix atmospheric N2, which are able to supply at least part of the nitrogen (N) required by the plant for its development, leading to significant savings in the use of nitrogen fertilizers Oliveira et al 2016;Soares et al 2016). In spite of this ability, factors such as competition among the bacteria introduced and others already established in the soil, along with exposure to adverse environmental conditions such as high temperatures and soil acidity, can compromise the efficiency of inoculation, with reflections on the BNF of the crop (Rufini et al 2011;Fonseca et al 2013;Figueiredo et al 2016;Oliveira et al 2016). To maximize the contribution of BNF, above all in tropical soils where acidity conditions are more accentuated, it is necessary to use strains that are more adapted, competitive, and efficient in the infection process (Ferreira et al 2009;2012;Rufini et al 2011;Fonseca et al 2013).…”

To maximize the contribution of biological nitrogen fixation in common bean, it is necessary to use bacterial strains that are more adapted, competitive, and efficient in the symbiotic process. In this regard, the aim of this study was to evaluate the agronomic efficiency (AE) of three bacterial strains isolated from acid soils with high Al content from the Amazon region in an Argissolo Vermelho Distrófico típico soil (Typic Rhodustults -USDA Classification) from the municipality of Formiga, MG, Brazil. We compared their AE to that of the reference strain CIAT 899 T and of two controls without inoculation (one without and another with 80 kg ha -1 of N-urea). The results indicated that inoculation with the strains UFLA 02-100 and UFLA 02-127 provides grain yield equivalent to inoculation with the reference strain and to the control with mineral N. Thus, both have potential for recommendation as inoculants for common bean.

Nesse sentido, objetivou-se avaliar, em um Argissolo Vermelho Distrófico típico do município de Formiga-MG, a eficiência agronômica (EA) de três estirpes isoladas de solos ácidos e com alto teor de Al da Amazônia e comparar suas EA à da estirpe referência CIAT 899 T e à de dois controles sem inoculação (um sem e outro com 80 kg ha -1 of N-ureia). Os resultados indicaram que a inoculação com as estirpes UFLA 02-100 e UFLA 02-127 propicia rendimento de grãos equivalente ao da estirpe referência e ao do controle com N mineral e que por isso, ambas têm potencial para ser recomendadas como inoculantes para o feijoeiro-comum.

Liquid Inoculation with Rhizobia in the Planting Furrow of Common Bean under No‐Till Is Feasible under Different Soil and Climatic Conditions

Common bean (Phaseolus vulgaris L.) producers that have adopted a high level of technology have shown interest in the use of liquid inoculant in the planting furrow, especially because of the practicality of this operation in large‐scale planting operations. However, consistent information on this practice is lacking for common bean, which requires studies to assist the producer in the choice of the inoculation method to be adopted and in determination of the application rates adequate for good performance of biological N2 fixation. To that end, two field experiments were conducted under the no‐till system under different soil and climatic conditions, both of them in irrigated areas. A randomized block experimental design was used, with four replications and seven treatments (three rates of liquid inoculation in the planting furrow; peat‐based or liquid inoculation on the seed; and two control treatments without inoculation, without and with N‐urea). The cultivar used was BRSMG Madrepérola and the rhizobial strain was CIAT 899 (±109 cells of Rhizobium tropici per milliliter or gram). Inoculation on the seed was performed shortly before sowing. Inoculation in the planting furrow at the rate of 3.5 L ha−1 not only leads to higher yields than inoculations on the seed but also ensures bean seed yields equivalent to those of the treatment with mineral N. Therefore, due to operational practicality, inoculation in the planting furrow is the most advantageous of the inoculations tested, regardless of the soil and climatic conditions in this study.

“…and genotype and to the density and activity of soil microorganisms (Moreira, 2008). Thus, high N concentration in the common bean plant are expected in soils with a high degree of fertility or with abundant populations of native rhizobia with high symbiotic efficiency (Ferreira et al, 2009;Figueiredo et al, 2016), conditions which were certainly not found in Patos de…”

Symbiosis of common bean with nitrogen-fixing bacteria can lead to a reduction in production costs and in environmental impacts. Considering the diversity of soils and climates, it is important to validate bacterial strains under different conditions to consolidate their recommendation as inoculants. Studies concerning the economic viability of Rhizobium inoculation in common bean are few, but they could assist in choosing the strain to be adopted. The aim of this study was to evaluate the performance of Rhizobium strains isolated from acid soils from the Amazon inoculated in seeds of the 'BRSMG Madrepérola' cultivar and to evaluate the economic viability of their use in the field. Four field experiments were conducted in the state of Minas Gerais, Brazil. A randomized block experimental design was used with four replications and seven treatments: inoculation with the strains CIAT 899 (Rhizobium tropici), UFLA 02-100 (R. etli), UFLA 02-68 (R. etli bv. mimosae), UFLA 02-127 (R. leguminosarum bv. phaseoli), and UFLA 04-173 (R. miluonense), plus two controls, one without inoculation + mineral nitrogen (N-urea) at a rate of 80 kg N ha -1 and another without inoculation and without mineral N. The strain CIAT 899 is already recommended for the manufacture of commercial inoculants, and the others, collected in the Amazon region, have proven to be highly effective in biological nitrogen fixation. Symbiosis of common bean with all the strains evaluated leads to satisfactory yields, with reduction in the application rate of mineral nitrogen and in environmental impacts and, consequently, reduction in economic costs, with higher profitability.
