Faba bean (Vicia faba L.) is one of the major leguminous crops grown in the world. It is important
source of protein for humans and animals. A 2-yr field study was carried out in the Research and Experimental
Center of Faculty of Agriculture at Moshtohor, Benha University, Egypt, during 2006/2007 and 2007/2008
seasons. The aim of this study was to determine the effect of six phosphorus (P) fertilizer treatments [0, 15, 30
kg P O , phosphate dissolving bacteria (PDB), PDB + 15 kg P O and PDB+30 kg P O / fed] and four spraying 2 5 2 5 2 5
treatments with Zinc [Tap water, 0.02, 0.04 and 0.06% as Zn EDTA(14% Zn)] on yield, yield components and
chemical contents of faba bean seeds cv. Giza 843. Adding 30 kg P O mixed with PDB markedly increased plant 2 5
height, No. of branches and pods/plant, 100-seed weight, seed yield/plant, seed and straw yields/fed, protein%,
N%, P%, N and P uptake. The results indicated that there were significant differences between foliar
applications of zinc treatments in all traits studied. The maximum values of 100-seed weight, seed yield/plant
and seed yield/fed were 71.86 g, 28.10 g and 1.657 ton, respectively, when plants received 0.04% Zn EDTA. The
interaction between phosphorus and zinc treatments were significantly affected on plant height, No. of
branches/plant, seed yield/fed, P%, N and P uptake in the combined analysis. Generally, it can be concluded
that adding 30 kg P O mixed with PDB under sprayed of 0.04% Zn EDTA (14% Zn) may be the recommended 2 5
treatment for improving the productivity of faba bean crop under the conditions of the present study.
