Medicinal and aromatic plants are an accessible affordable culturally appropriate source of primary health care for more than 80% of world{u2019}s population. Menthe species are belong to the family lamiaceae and used for their flavoring and medicinal properties widely throughout different countries of the world. Both compost, as an organic waste, and plant growth promoting rhizobacteria (PGPR), are considered a valuable, inexpensive and source of plant nutrients as well. During his study, pot and field experiments were conducted in the greenhouse of ARC, Giza and own farm at El-Fayoum governorate to evaluate the response of two species of mint (spearmint and Peppermint) to application of two types of compost 1) plant residues and 2) plant + animal residues. PGPR used are 1) Azospirillum brasilense and Azotobacter chroococcum as bacteria N2 fixing bacteria, 2) Bacillus megaterium as phosphate dissolving bacteria, 3) Bacillus circulans as potassium releasing bacteria, 4) cyanobacteria i,e (anabaena, nostoc, spirulina ) as N2-fixing blue green algae as well as to study some growth yield and yield components as affected by application various organic and bio fertilizers. Under greenhouse experiment conditions the obtained results indicated that, application of various PGPR did support both vegetative growth and yield of mint plants
