Abstract

In order to study the effects of application methods and added levels of iron (Fe) and manganese (Mn) on quantitative and qualitative characteristics of wheat, two field experiments in three factors, i.e. micronutrients (without, iron and manganese)  methods of application (grain soaking, soil and foliar application) and added levels (low, medium and high) in form of randomized complete design with four replications and nineteen treatments (1+2X3X3) were conducted at Sids of Agricultural Research Station , A.R.C. Beni Swif Governorate . Variance analysis and comparing the means showed that , irrespective of methods and levels application of iron and manganese surpassed the check treatment in their effect on growth, yield and its components as well as nutrient content and uptake in grains and straw, except 1000- grain weight which was not effect . However manganese concentration was significantly decreased due to iron application . Maximum dry weight , number of spikes / m2 number of grains / spike , grain and N, P, K and Fe concentration and uptake belonged to the spraying ferrous sulphate with a concentration of 0.2 %  . In general, foliar spraying surpassed the other two methods with all studied parameters. Moreover, soil application gave significant effect as soaking treatment . Also, the results indicate that using Fe and Mn at the medium level (0.2 % as iron or manganese sulphate in foliar or soaking methods and 5 kg Fe or Mn sulphate / fed in soil application) gave highest values of the studied parameters comparing with low or high added levels . Finally , as foliar application at rate of 0.2 % iron sulphate improved wheat quality and quantity of wheat plant.
