8 p, 1.1 MB Estimation of phenotypic variability in symbiotic nitrogen fixation ability of common bean under drought stress using 15 N natural abundance in grain / Polania, Jose (Universitat Autònoma de Barcelona. Facultat de Biociències) ; Poschenrieder, Charlotte (Universitat Autònoma de Barcelona. Facultat de Biociències) ; Rao, Idupulapati (Centro Internacional de Agricultura Tropical (Colombia)) ; Beebe, Stephen (Centro Internacional de Agricultura Tropical (Colombia))
Common bean (Phaseolus vulgaris L. ) is the most important food legume, cultivated by small farmers and is usually exposed to unfavorable conditions with minimum use of inputs. Drought and low soil fertility, especially phosphorus and nitrogen (N) deficiencies, are major limitations to bean yield in smallholder systems. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Organic cultivation methods would be a good alternative to conventional cultivation, avoiding the use of industrial fertilizer and reducing the risk of eutrophication, but its impacts on soil elemental composition and stoichiometry warrants to be clearly stated. [...]
