Seyam, H.M.M., Seham, M. Abd EL- Azem Anda.E. Hassanein( 2012). Effect Of Seed Coating With Zn And Cu As Mineral Or Chelating Form On Wheat YieldEgypt . J. Of Appl. Sci.,(2012) 27 (5):301-310
Abstract: Two field experiments were conducted at El-Tahrir South on the Farm of Ali Moubark, Agric., Res. Center during the growing seasons of 2009 and 2010 to study the effect of seed coating with Zn and Cu on wheat plants (triticum aestivum,L.). Zinc and Cu were applied individually as seed coating (mineral or chelating) at rates of 0.2, 0.4 and 0.6 g/kg seed. Obtained results show that the grains, straw and biological yields were positively affected by the application of Zn and Cu as coating seed in both mineral and/or chelating from, the superior values were obtained at the second applied (0.4g/kg seed) treatment. The maximum responses were observed under Zn and Cu addition in chelating form comparing with the non-chelating ones. Macro and micronutrients content (N, P, K, Fe, Mn, Zn and Cu) in both grains and straw of coated seeds were significantly increased, chelating form being an almost similar to that of wheat plant growth.
