Concentration of 5 per thousand Vkvdhay fertilizer for the use of the sulfate form. Spraying was done in two stages stem and tassel emergence. The results showed that the effect of treatments on nitrogen, phosphorus, potassium, iron, zinc, manganese, seed yield, forage yield and dry matter yield were significant.Effect of treatments on yield was significant at the 1% level. The highest grain yield of 5.75 tons per ha foliar spray of iron, zinc and manganese and the lowest yield of 4.72 tons per hectare in control was obtained.The highest fresh and dry matter yield, 22/55 and 95/13 tons per ha foliar spray of iron, zinc and manganese and the lowest is 17/49 and 67/9 tons per ha and the control group.
