The purpose in this research was to study the effects of Vermicompost and poultry manure on yield and yield components of the medicinal plant coriander (Coriandrum sativum L.) in the Shahr-e- Ghods region. A factorial experiment using the randomized complete block design with three replications was conducted in the Islamic Azad University of Shahr-e- Ghods. The first factor was three levels of Vermicompost: (0%), (15%), (30%), the second factor three levels of poultry manure: (0%), (10%), and (20%), and the third factor the mutual effects of these two factors. Results showed that in most studied characters there were significant differences between the applied treatments and the control. Application of Vermicompost and poultry manure increased seed yield, percentage of essential oils, etc., but the Vermicompost treatment caused the largest improvements in most characters. For example, the maximum seed yield (5.79) was achieved with the application of 30% Vermicompost, while these treatments had the least effect on the 1000-seed weight, the number of stems per plant, and the harvest index. The mutual effects of applying 30% Vermicompost and 20% poultry manure resulted in the highest percentage of essential oils content (1.73 percent) compared to the control, while these treatments did not influence the number of stems per plant, the biological yield, the number of umbels per plant, and the essential oils yield. Results of this experiment showed that application of Vermicompost and poultry manure could play an important role in increasing the efficiency of coriander production.
