Effect of different sources and rates of nitrogen fertilizer on maize grain yield, macro- and micronutrients uptake at Middle Egypt region [electronic resource].

Includes reference.

A field experiment was carried out during the two successive seasons of 2007 and 2008 at EI-Badrasheen, 6 October, governorate, Egypt to study the effect of different nitrogen sources i.e., urea, ammonium sulphate and calcium nitrate at rates (0, 100, 200 kg N/Fed.) and their interaction on growth characters, nutrients content, grain yield and its components of maize plants (Zea mays L. C.v single hybrid 10).
