Common bean (Phaseolus vulgaris L.) represents the main source of protein for the Brazilian and other Latin-American populations. Unlike soybean, which is very efficient in fixing atmospheric N2 symbiotically, common bean does not dispense with the need for N fertilizer application, as the biologically fixed N (BNF) seems incapable to supplement the total N required by the crop. A experiment under controlled conditions was conducted in Piracicaba, Brazil, to assess N2 fixation of 25 genotypes of common bean (Phaseolus vulgaris L.). BNF was measured by 15N isotope dilution using a non-N2 fixing bean genotype as a reference crop. The common bean genotypes were grown in low (2.2 mg N kg-1 soil) or high N content soil (200 mg N kg-1 soil), through N fertilizer application, as urea-15N (31.20 and 1.4 atom % 15N, respectively). The bean seeds were inoculated with Rhizobium tropici CIAT 899 strain and the plants were harvested at grain maturity stage. The contribution of BNF was on average 75% of total plant N content, and there were differences in N fixing capacity among the bean genotypes. The most efficient genotypes were Horizonte, Roxo 90, Grafite, Aporé and Vereda, when grown in high N soil. None of the genotypes grown in low N soil was efficient in producing grains compared to those grown in high N soil, and therefore the BNF was not able to supply the total N demand of the bean crop. |

The adoption of adequate technologies for food, biomass and fiber production can increase yield and quality and also reduce environmental impact through an efficient input application. Precision agriculture is the way to decisively contribute with efficient production with environment protection in Brazil. Based on this, recently Embrapa established the Brazilian Precision Agriculture Research Network, with the objective of knowledge generation, tools and technologies development to enhance the agricultural production systems, and to increase the competitiveness and sustainability of Brazilian agribusiness. The project is composed by 214 researchers, 19 research centers, 15 experimental fields, comprising four Brazilian ecosystems and the soybean, maize, wheat, rice, cotton, pasture, eucalyptus, pines, grapes, peach, orange and sugar cane crops. All research areas are being mapped for soil fertility and electrical conductivity, elevation, remote sensing and yield and the results are stored in an online data bank. Several knowledge areas are integrated for optimization of financial resources and results. Research, development and innovation will be focused on those crops responses to PA, as well as on the development and adaptation of tools and technologies to improve of PA. Project staff is being trained in PA concepts, tools and technologies, as geostatistical treatment of data collected and GIS. Training courses and technologies transfer for technicians and producers are being organized. Academic and extension events will support partnership between private and governmental sectors to enhance PA adoption. The PA Network is also promoting the dialogue between the agribusiness, private, public and third sector. In the near future expect results are the dissemination of the AP concepts and technologies and make AP present in the daily Brazilian agricultural activities incorporating technologies and practices for sustainable management.
