In order to evaluate the effect of different intercropping patterns and fertilizers on some growth characteristics and biomass of faba bean (Vicia faba L.) an experiment was conducted as factorial based on randomized complete block design with 12 treatments and three replications at the Research Farm of the Faculty of Agriculture, University of Tabriz, Iran in 2014. The first factor was four cropping systems including monoculture of faba bean; row intercropping of faba bean with cumin (Cuminum cyminum L.) at three patterns (1 row faba bean-1 row cumin; 2 rows faba bean-2 row cumin; 4 rows faba bean-4 row cumin and the second factor was three levels of fertilizers including 100% chemical fertilizer, 50% chemical fertilizer + biofertilizer (Azoto barvar + Barvar 2) and vermicompost. Results showed that the fertilizer had significant effect on plant height of faba bean. The greatest faba bean height was observed in 100% chemical fertilizer that was not significantly different with 50% chemical fertilizer +bio-fertilizer. The interaction effect of fertilizer and cropping pattern was significant on leaf number of faba bean. The highest chlorophyll content index was observed in 100% chemical fertilizer. The biomass of faba bean was significantly affected by fertilizer and cropping patterns. The highest biomass (3887.5 kg/h) was observed in 100% chemical fertilizer and the lowest was observed at vermicompost treatment. In comparison of intercropping patterns the 1-1 and 4-4 faba bean-cumin patterns could be recommended to growers for higher faba bean growth and production.
