Efficiency of corncob-derived biochar and plant growth-promoting rhizobacteria as growth promoters for Coffea arabica L. seedlings
Corncob-derived biochar and plant growth-promoting rhizobacteria (PGPR) can improve soil fertility and plant performance, but their co-application in Coffea arabica L. nurseries remains poorly characterised. This study evaluated corncob-derived biochar combined with Bacillus megaterium S2-4a1 under well-watered greenho...
