| Summary: | To investigate the effects of different intercropping arrangements on barley and vetch forage yield and to find the land use advantage in the intercropping system, an experiment was carried out based on randomized complete block design with eight treatments and three replications at the Research Farm, Faculty of Agriculture, University of Tabriz in 2009. Treatments were barley and vetch monocrops, additive intercropping respectively barley: vetch in the ratio of 100:15, 100:30 and 100:45 and substitutive intercropping respectively, barley: vetch in the ratio of 2:1, 3:1 and 4:1. The results showed that, the highest amount of dry forage yield is obtained from 100:15 intercropping ratio. The highest intercropping advantage (4.41) was related to 100:15 additive intercropping ratio. Land Equivalent Ratio revealed that in 100:30 ratio, yield was %32 more than monocropping. The highest Relative Yield Total abtained from 100:30 additive intercropping was 1.14. Also, the greatest amount dry forage is 7030kg/ha in 100:15. Based on results of this experiment it can be stated that for the production of hay, additive intercropping method is superior on substitutive intercropping planting and monocroping sowing of barley and vetch. |
