- Abstract
During seed production, nutrients (nitrogen) and climatic conditions (water) can affect their physiological quality. Therefore, the influence of common bean cultivation with the use of more sustainable techniques such as co-inoculation with nitrogen-fixing bacteria and the reduction of the irrigation depth on the quality of the seed produced should be analyzed. The objective of this study was to evaluate the physiological quality of seeds coming from the common bean cultivation submitted to inoculation and co-inoculation with Rhizobium tropici and Azospirillum brasilense under two irrigation depths. The experiment conducted in the field consisted of randomized blocks with a split-plot design with two irrigation depths as plots (recommended and 75% of the recommended) and five forms of nitrogen supply as subplots (control noninoculated with 40 kg ha-1 of nitrogen in topdressing; control non-inoculated with 80 kg ha-1 of N in topdressing; A. brasilense inoculation with 40 kg ha-1 of N in topdressing; R. tropici inoculation with 40 kg ha-1 of N in topdressing; and co-inoculation of A. brasilense and R. tropici with 40 kg ha-1 of N in topdressing). Common bean cultivation with 40 kg ha-1 of N in topdressing without inoculation provides satisfactory physiological quality of seeds, and there is no need to apply higher doses of nitrogen and inoculation. Bean seeds can be produced with the recommended 75% depth, without decrease their quality.
