The effect of the application method of iron, zinc and manganese on the yield and quality of barley grain

Abstract

To evaluate the methods of uses microelements of iron, zinc and manganese on yield and quality of barley, this research was conduct at Ahar agricultural research station of East Azerbaijan. Basis of thorough randomized complete block design with their replications and 15 treatments, include: T1: no use of micro elements (as a control), T2: Fe soil application, T3: Mn soil application, T4: Zn soil application , T5: T2+T3, T6: T2+T4, T7:T3+T4, T8:T2+T3+T4, T9: foliar spraying of Fe, T10: foliar spraying of Mn, T11:foliar spraying of Zn, T12: foliar spraying of Fe+Mn, T13: foliar spraying of Fe+Zn, T14: foliar spraying of Mn+Zn, and T15: foliar spraying of Fe+Mn+Zn. Soil application of Fe, Mn and Zn from ferrous sulphate, manganese sulphate and zinc sulphat, as the rates of 100, 60 and 100 kg. ha^-1, respectively and rates of foliar spraying 0.005 from the same of soil application sources. Variance of analysis showed that the effect of treatments was significant in the respect of attributes such as amount of Mn, Iron, Zinc and protein in grain. The maximum yield of grain (3587 kg. ha-1) acquired from the soil application of Mn and Zn, while the maximum amount of protein. Fe and Mn in grain were obtained from foliar application of Fe, Mn and Zn. There was a positive and significant and Cohesiveness amount most numerous attributes. The soil application performed properly as a whole state for grain yield and biomass, but the foliar spraying has operated better than the soil application for quality that is amount of grain yield and amount of protein. Its internals that intensity of these elements namely (Fe, Mn and Zn) increased in grain in low. Consumption elements in addition to increasing amount of protein.
