The advantage of intercropping on row of oat and vetch in Ahvaz

In order to study of yield and some forage quality traits of mixcropping on rows of oat and vetch, an experiment was conducted based on randomized complete block designed with seven treatments and three replications at the research farm of Agriculture faculty of Shahid Chamran University of Ahvaz in 2014-2015 growing season. Treatments were included different sowing ratios of 100: 0, 70:30, 60:40, 50:50, 40:60, 30:70 and 0: 100, respectively, oat and vetch. mixcropping was performed as a replacement method. The evaluated characteristics were included wet and dry forage yield, crude protein yield, percent crude protein, crude fiber, ash, percent soluble carbohydrates, oat and plant height, tiller numbers. The highest forage yield (105.26 t ha-1), dry (29.47 t ha-1) and protein yield(2.27 t ha-1) were obtained from 60 percent of oat and 40 percent vetch sowing ratio. The higher percent of crude protein(17.49 percent) and the most percent of ash (7.37 percent) and the lowest percent of crude fiber was obtained in monoculture of vetch. The highest amount of soluble carbohydrates(12.66 percent) was obtained in 30 percent of oat and 70 percent vetch. The highest land equivalent ratio for wet (1.26) and dry(1.60) forage yield and protein yield(1.50) was obtained, respectively, 50percent and 50percent of oat and vetch and 60percent oat 40percent vetch. According to the results in this experiment it seems that oat and vetch mixcropping on row in terms of forage quality and quantity, can recommend as an appropriate manner compared to monocultures of the studied species.
