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.

A field experiment was conducted based on randomized complete block design with three replications at the Agricultural Research Station of Payamenoor University of Nagadeh, Iran during growing reason of 2009-2010. Treatments included bean and dill monoculture, row intercropping (one row of dill + one row of bean), strip intercropping (two rows of bean+ four rows of dill and four rows of bean+ two rows of dill) and intra- row intercropping (50% dill+ 50% bean). The results showed that the highest and the lowest grain yield and biological yield of bean were achieved in row intercropping and intra- row intercropping (50% dill+ 50% bean), respectively. The plants were planted as replacement method. The highest grain yield (1630 kg/ha) and biological yield (3593 kg/ha) of bean were obtained at row intercropping and the lowest grain yield (414 kg/ha) and biological yield (870 kg/ha) of bean were achieved in intra- row intercropping, respectively. The results showed that the maximum grain yield (340 kg/ha) and biological yield (1926 kg/ha) of dill were obtained at monoculture and the minimum grain yield (340 kg/ha) and biological yield (1926 kg/ha) of dill were achieved in strip intercropping (four rows of bean+ two rows of dill intercropping), respectively. The highest essential oil percentage and essential oil yield were obtained by row intercropping, compared with other treatments. The highest (1.9) and the lowest LER (0.80) values were obtained from row intercropping and intra- row intercropping patterns, respectively. The maximum population of pest obtained under monoculture, while the minimum population of biological predators was observed under intra- row intercropping, respectively.
