Abstract
The present investigation was conducted to study the differential response of recently three released hybrids to three inorganic nitrogen sources (urea and ammonium sulfate as NH4+-N forms and ammonium nitrate as NH4+NO3- form) and different times and methods of its split application in terms of their yield and yield attributes as well as some nitrogen parameters.
