In order to study of use advantage in the intercropping system fennel (Foeniculum vulgare Mill) and fenugreek (Trigonella foenum-graecum L) in different ratios of intercropping and sole cropping, an experiment with use replacement and additive intercropping based on randomized complete block design with three replications was conducted at the Research Station of Faculty of Agriculture, University of Zanjan, Iran, during growing season 2012. Treatments included additive intercropping in three levels (100 percent fennel + 33, 66 and 100 percent fenugreek), replacement intercropping in six levels (1:1, 1:2, 2:1, 2:2, 1:3, 3:1), Sole fennel and Sole fenugreek. Results showed that the highest grain yield of Fenugreek was obtained in pure stand of Fenugreek and the lowest of mentioned trait was obtained in the 75 percent fennel + 25 percent fenugreek (3:1) replacement series. Also the highest and the lowest fennel grain yield were obtained in 100 percent fennel + 33 percent fenugreek additive series and 25 percent fennel + 75 percent fenugreek (1:3) replacement series respectively. yield of essential oil at 100 percent fennel + 33 percent fenugreek additive series were higher compared with sole cropping. The highest Land Equivalent and Relative Value Total obtained from 100 percent fennel + 33 percent fenugreek additive series. The highest Actual Yield Loos or gain (AYL) and intercropping advantage (IA) obtained from 25 percent fennel + 75 percent fenugreek (1:3) replacement series. Aggressively index revealed that in most sowing ratios fennel was dominant and fenugreek was defeated.

To evaluate the yield components, yield and land equivalent ratio affected by relay intercropping of sunflower (Helianthus annuus L.) with faba bean (Vicia faba L.), a field experiment was arranged based on a randomized complete block design with three replications at the Agricultural Research Station Payamenoor University of Nagadeh, Iran during growing reason of 2012-2013. The treatments included row intercropping )one row of sunflower + one row of faba bean(, strip intercropping )two rows of faba bean + four rows of sunflower, four rows of faba bean + two rows of sunflower, three rows of faba bean + three rows of sunflower( and monoculture faba bean and sunflower. The results indicated that the relay intercropping patterns had significant effect on studied traits of sunflower and faba bean (except number of seed per pod of faba bean). The highest seed yield of sunflower (4140 kg/ha) and faba bean (2567.33 kg/ha) were obtained from row intercropping and the lowest seed yield of sunflower (3136.67 kg/ha) and faba bean (1957 kg/ha) were obtained in their monoculture. The oil percentage of all intercropping treatments was higher than monoculture. The maximum land equivalent ratio (1.85) and actual yield loss (1.74) were calculated in row intercropping and the highest intercropping advantage (1.25) was achieved in four rows of faba bean + two rows of sunflower. The results showed that the use of relay intercropping results in better utilization of environmental resources and increased crop production compared to monoculture of the same species.
