Abstract:
In order to evaluate the density، population and insect fauna diversity and agronomical yield in intercropping faba bean (Vicia faba L.) andcoriander (Coriandrum sativum L.)، a field experiment was conducted based on a randomized complete block design with three replications at the farm located in Nagadeh، West Azerbaijan province، Iran during growing season in 2012-2013. Treatments included 75 percent faba bean + 25 percent coriander، 50 percent faba bean + 50 percent coriander، 25 percent faba bean + 75 percent coriander and their monoculture. Results showed that the maximum population of pest obtained under monoculture، while the maximum population of biological predators was observed under 50 percent faba bean + 50 percent coriander، respectively. The highest seed yield and biological yield of faba bean were obtained in monoculture and the lowest grain yield and biological yield were achieved in 75 percent faba bean + 25 percent coriander، respectively. The results showed that the maximum seed yield and biological yield of coriander were obtained at monoculture، and the minimum seed yield and biological yield of coriander were achieved in 75 percent faba bean + 25 percent coriander، respectively. There was no significant difference between treatments in the essential oil percentage but the highest essential oil yield was higher than other treatments. The highest (1. 58) and the lowest LER (1. 40) values was obtained from 75 percent faba bean + 25 percent coriander and 50 percent faba bean + 50 percent coriander، respectively.
