چکیده
in order to study the impact of replacement and additive intercropping series on yield and yield components of bean and ajowan as a medicinal plant, an experiment was conducted based on a randomized complete block design with three replications at the agricultural research station, shirvan college of agriculture and natural resources during growing season of 2012-2013. nine replacement and additive intercropping series of ajowan with bean such as 0:100, 25:75, 50:50, 75:25, 100:0, 100:25, 100:50, 25:100 and 50:100 were considered as treatment. the results showed that the effect of intercropping series was significant (p 0.01) on yield components, biological yield, seed yield, harvest index and essential oil yield of ajowan and yield components, biological yield, seed yield and harvest index of bean. the maximum biological and seed yield of ajowan were observed in its monoculture with 192.82 and 113.19 g.m-2 and these minimum were in 50%bean+100%ajowan with 43.50 and 12.79 g.m-2, respectively. the highest and the lowest essential oil yield of ajowan were obtained in its monoculture and 100%bean+25% ajowan with 3.51 and 0.54 g.m-2, respectively. the highest and the lowest biological yield and seed yield of bean were observed in its monoculture (1984.87 and 893.81 g.m-2) and 25%ajowan+100%bean (552.42 and 252.50 g.m-2), respectively. range of partial land equivalent ratio (ler) for ajowan was calculated with 0.12-0.55 and it was 0.28-0.83 for bean. the highest total ler was computed in 50%bean+100%ajowan with 1.14.

Effect of Planting Patterns and Vermicompost on Yield and Yield Components in Maize and Beans Intercropping
Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...
