Resumen
Descripción
The inoculation of cereal crops with plant growth-promoting bacteria (PGPB) is a potential strategy to improve fertilizer-N acquisition by crops in soils with low capacity to supply N. A study was conducted to assess the impact of three inoculants on grain yield, protein content, and urea-15 N recovery in maize (Zea mays L.) under Cerrado soil and climate conditions.
