Abstract
Two field experiments were conducted during 1998 and 1999 summer seasons in Biddeen Village, El-Mansoura Center, Dakahlia Governorate. The presented work aimid to investigate the productivity of rice as affected by different nutrition levels from both nitrogen and copper as well as their interactions on different physiological and morphological characters of rice.
A split plot design with four replications was used. The main plots were devoted to four levels of foliar application of copper i.e. (0, 11.5, 23.0, 34.5kg CuSO4 /fed.), the sub-blots were devoted to four levels of soil nitrogen application i.e. (0, 30, 60 and90 kg N/ fed.).
