“…These studies are in line with three Sustainable Development Goals (SDG) of the United Nations (UN): a) end hunger, achieve food security and improved nutrition and promote sustainable agriculture; b) take urgent actions to combat climate change; and c) conserve and sustainably use marine resources. Scientifically, this type of investigation also helps genetic improvement programs, which aim at genotypes that are efficient and responsive to nutrients (Silva et al, 2016).…”

Common beans are the main source of protein in underdeveloped countries, and nitrogen (N) is one of the nutrients the most limits the productivity of this crop. This study, under field conditions, aimed to: a) determinate through efficiency indices how N is used by 16 cultivars of common beans; and b) classify these cultivars regarding use efficiency and responsivity to N application. The experimental design was in randomized blocks in split-plot scheme, with four replicates. Main plots consisted of 16 cultivars of common beans commercially classified as ‘Carioca type’. Subplots comprised two rates of N: 20 and 120 kg ha-1 applied as top-dressing. The evaluations were number of pods per plant and grains per pod, hundred-grain weight, shoots dry matter at full flowering, straw and grains dry matter at physiological maturity and grain yield. Based on the dry matter and its nutrient contents, the N accumulations were calculated in shoots and grains. The agronomic, physiological, agro-physiological, recovery and use efficiencies of N were calculated. Cultivar BRSMG Uai stands out by agronomic, physiological, recovery and use efficiencies of N. Genotypes BRSMG Uai, BRS FC402, IPR Campos Gerais, IPR Maracanã and TAA Bola Cheia are efficient and responsive to top-dressing N application.

“…In eutrophic oxisoil, root structure of IAC Imperador did not show significant differences compared to Dor-364, showing similar values of root length and volume; in addition, despite of Dor-364 yield be slight lower than IAC Imperador, no significant differences were observed (SILVA et al, 2016).…”

“…When evaluating the phosphorus uptake efficiency of IAC Imperador and Dor-364 genotypes in previously studies (SILVA et al, 2014(SILVA et al, , 2016, only inorganic fertilizers were used. These findings might suggest that phosphorus uptake efficiency by the plants might correlate with the ability of the rhizosphere microbial to use inorganic P. It can also be proposed that Dor-364 is more efficient when using organic fertilizers; however, further studies are required to verify this statement.…”

“…This strongly suggest that Dor-364 rhizosphere has an interaction much stronger with its rhizosphere microbiome than the genotype IAC Imperador. (CHIORATO et al, 2012;SILVA et al, 2014bSILVA et al, , 2016VANCE;UHDE-STONE;ALLAN, 2003). In this sense, the absence of these traits in Dor-364 genotype, possibly leaded to a higher reliance on its rhizosphere microbiome.…”

“…Despite of IAC Imperador be classified as responsive to phosphorus addition (SILVA et al, 2014b(SILVA et al, , 2016, its rhizosphere microbial community only responded to TSP additions in L100 and L200. Amendment of the soil with L200, which largely exceeds plants nutritional requirements, promoted on IAC Imperador the enrichment of members of many phyla such as Verrucomicrobia, Planctomycetes, Actinobacteria and Proteobacteria compared to phosphorus limiting conditions.…”
