The present investigation was carried out to study the effects of inorganic, organic nitrogen fertilizers and activators (Humic and Fulvic acid) on chemical composition and productivity of corn. This study was conducted at Shandweel Agricultural Research Stations, Sohag Governorate, Egypt, and is situated at 26.60 N latitude and 37.70 E longitude. Its altitude is about 70 m above mean sea level. Also, this study was performed during two successive summer seasons 2014 and 2015. The experiments were laid down in split-split plot design with four replications. The treatments were included mineral nitrogen application in three levels (i.e. 60, 90 and 120 kg N fed.-1), organic and bio fertilizer application (without organic and bio fertilizer, 10 m3 FYM fed.-1 and Microbeine inoculume) as well as foliar spray of humic acid (water spraying, humic and fulvic acid spraying). The obtained results revealed that the interaction effects of all factors under study were significant for all studied traits.
