To assess the effects of bio-fertilizer and some of microelements on quantitative and qualitative characteristics of sorghum (var. Pegah), this experiment was conducted at the research farm of the University of Tehran (Karaj-Iran) in 2011. The experiment was arranged as split plot based on complete randomize design block with four replications. Two levels of mycorrhiza (inoculated and non-inoculated) and three levels of foliar application of iron (zero, four and eight per thousand) along with three levels of application of zinc (zero, three and six per thousand) were allocated to main and subplots respectivly. The results indicated that inoculation with mycorrhiza and application of micronutrients had positively significant effect on dry yield, plant height, shoot weight, leaf weight, crude protein, water soluble carbohydrates and ash (p<0.01) and reduced acid detergent fiber (p<0.05). However, foliar of Fe and Zn had no significant effects on root colonization. Also, investigated factors had no significant effects on number of leaves. The treatment of mycorrhiza and foliar application of the Fe and Zn in concentrations of four and three per thousand (respectively) produced the maximum of dry yield. This treatment increased yield by 40% compared with control. Based on the obtained results, treatment of myco-Fe4Z3 can be recommended for increasing yield and improving qualitative characteristics of forage sorghum (var. Pegah) in Karaj region.

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 using 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) were 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) were obtained, respectively, 50 percent and 50 percent of oat and vetch and 60 percent oat + 40 percent vetch. According to the results of the present study, 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.
