POTENTIAL EFFECTS OF FELDSPAR AND BIOCHAR-BASED CO-INOCULATION OF RHIZOBACTERIA IN COWPEA PLANTS
In light-textured areas, soil deterioration lowers available nutrients and biological activity, therefore endangering the yield of dryland grain legumes. This study investigates whether combining feldspar, biochar, and two Bacillus strains (B. circulans and B. amyloliquefaciens) with plant growth–promoting rhizobacteri...
