In order to investigate the effect of source and rate of nitrogen fertilizer on yield and quality of sweet corn, a field study was conducted in 2011 cropping season in Agriculture Experiment Station of College of Agriculture, University of Guilan. A randomized complete block design with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 46, 92 and 138 kg N ha-1) and integrated N of chemical and biological (23 kg N ha-1 + 1 ton ha-1 Vermi-compost, 46 kg N ha-1 + 2 ton ha-1 Vermi-compost, and 69 kg N ha-1 +3 ton ha-1 Vermi-compost) and organic sources (2, 4 and 6 ton ha-1). Effect of source and rate of nitrogen fertilizer on fresh ear yield, grain yield canned, grain protein amount and dry matter digestibility percent had significant. With increscent nitrogen at treatments nitrogen fertilizer, organic ant integrated farming yield fresh ear, grain yield, grain protein amount and dry matter digestibility percent increased. Maximum yield fresh ear was obtained with 69 kg N ha-1 + 3 ton ha-1 Vermi-compost with an average 14595.9 kg ha-1. Maximum forage yield and dry forage yield obtained with an average 18619.5 and 3593 kg ha-1 at treatment with 69 kg N ha-1 + 3 ton ha-1 Vermi-compost. Results of this research showed that the best grain yield and quality, and forage yield and quality of sweet corn were obtained in integrated farming and organic methods in Rasht region conditions and same climatology conditions.
