Efficiency of Arbuscular Mycorrhizal Fungi in the Development of Cowpea

Cowpea is an important and strategic agricultural crop for Northeast of Brazil, once it combines nutritional value, climate adaptability and soil quality improvements. The objective of this study was to evaluate the efficiency of arbuscular mycorrhizal fungi (AMF) communities on the growth and mineral nutrition of cowpea. The experiment was conducted in a completely randomized design (CRD), with three replications e envolveu tratamentos com inoculação de FMA referências; Inoculação de Comunidades de FMA oriundas de diferentes sistemas de uso do solo; Ausência de inoculação de FMA. After 80 days of cowpea cultivation, were determined plant growth and nutrition parameters, mycorrhizal colonization of the roots and indentifications of AMF species. Results showed that the AMF community from coffee intercropped with grevílea had results close to the RT, with a dry mass value (DMAP+RDM) of 4.31 g and phosphorus content of 7.60 g/kg-1. High species richness of AMF from the study areas was recovered after 80 days of cowpea cultivation
