Biochar amendment of soil proved to improve soil quality and retain nutrients, thereby enhancing
plant growth. A greenhouse experiment was carried out to investigate the combined effects of biochar and plant
growth promoting endophytic bacteria (PGPE) (Pseudomonas spKY6489821.1 and Klebsiella oxytoca
KY648983.1) or plant growth promoting rhizobacteria (PGPR) (Paenibacilluspolymyxa MG309677.1 and
Ochrobactrum intermediumMG309678.1) on the growth and yield of pepper plants. Compared with individual
application, the combination of biochar with PGPE exhibited significant increases in all predestined parameters
(soil enzymes, growth parameters, some macro and microelements, chlorophyll, carotenoids, sugar, free amino
acid, vitamin C, TSS and yield). Similarity, there were remarkable increases in the previous parameters in plants
treated with biochar in the presence of PGPR followed by chemical fertilizers. The present study demonstrates
that the beneficial effect of biochar not only improve the soil properties but also enhanced the performance of
biofertilizers in promoting plant growth
