Co-inoculation of Rhizobium tropici and Azospirillum brasilense in common beans grown under two irrigation depths
ABSTRACT The alternative technique of co-inoculation or mixed inoculation with symbiotic and non-symbiotic bacteria has been studied in leguminous plants. However, there are few field studies with common beans and under the influence of the amount of irrigated water. Thus, the objective of this stud...
