| Abstract | ||
| Three field experiments were conducted to study the effct of Zn , Mn and Fe nutrients by the coating method on wheat grown on sandy calcareous and alluvial soils . Three rates of each element; 0.15, 0.30 and 0.60 g /Kg grain were used compared with the control . Obtained data of yield components and flag leaf analysis are summatized as follows : wheat yield was markedly affected by increasing the amount of coating Zn, Mn and Fe up to the rate of 0.30 g of each element . The percentage of wheat yield increase using Zn-application was found to be 13.7 % , 14 . 7 % and 15 . 6 % over the control for the sandy , calcareous and alluvial soils , respectively. Corresponding increase of Fe application was 15.2 % , 22.2 % and 11.8 % over the control . Application of Mn at the rate of 0.15 g / kg grain gave a similar effect by nearly 13 % over the contrlol for the different soils used. The response of straw yield to manurial treatments nearly followed the same trend of wheat grain. Superior protein yield of wheat grain was obtained by Mn application, followed by Fe and Zn treatments. Analysis of flag leaf taken at the booting stage indicated that N, P, K, Zn, Mn and Fe concentrations were also affected. | ||
