Context: This study examined the effect of biological and organic fertilizers on the growth parameters of an herb named Salvia officinalis. Settings and Design: Its characteristics include germination, number of leaves, length, and dry weight of root and shoot. A total of 11 treatments (4 replications) including a vermicompost treatment and a cow manure treatment (both at 25% and 50% levels); four vermicompost treatments of 25% and 50% levels mixed with Azotobacter and Azospirillum and three treatments of Azotobacter, Azospirillum, and control constituted the focal point of the study. Results: The results obtained from the statistical analyses performed at P ≤ 0.05 are as follows: (1) Azospirillum and 50% cow manure treatments had the most and least significant effects on germination and root length, respectively; (2) once combined with Azospirillum, 25% vermicompost treatment affected the length of the root and shoot more significantly compared to the vermicompost and Azospirillum treatments delivered individually; (3) the number of leaves and dry weight of root and shoot were not significantly different across the treatments; and (4) 25% vermicompost and 50% cow manure and Azospirillum treatments exerted the maximum influence upon the number of leaves and the dry weight of shoot and root. Conclusion: Although treatments had different effects, they were not significantly different. The 25% vermicompost treatment had a better effect than its 50% level counterpart.
