Abstract
This investigation was carried out in the Agricultural Experimental Farm at Fac. Agric., Assiut Univ., during the two winter growing seasons 2009/2010 and 2010/2011 to study the effect of grain soaking into Fe, Zn and Mn solutions on the productivity and quality of wheat. The used experimental design was a Complete Randomized Block Design in split-plot with four replications. Wheat varieties (Giza 168 and Bani-Swef 1) were allocated in the main plot, while micronutrient treatments (Fe, Zn, Mn, Fe+Mn, Zn+Mn, Fe+Zn and Fe+Mn+Zn) were distributed in the sup-plot. The plot area was 3x3.5 m2. The results could be summarized as follows:
