Beyond broad-spectrum fertilization: genotype-specific responses of cowpea to integrated bio-inorganic amendments in Edo State, Nigeria
This study evaluated the in vitro plant growth-promoting traits of isolated rhizobacteria and their in vivo synergistic effects when co-applied with inorganic fertilizers on the yield of three cowpea varieties (IT90K-82-2, IT89KD-391, and IT99K-593-1-1). Molecular characterization via 16S rRNA sequencing identified the...
