Two field experiments were conducted during the two successive winter seasons of 2009/2010 and 2010/2011 in a private Farm in Bani-Ebeed District, Dakahlia Governorate. The aim is to study the effect of organic, bio, mineral fertilization and their interactions on yield and quality of carrot cv. shantenay. In general, it can be concluded that: 1-     Fertilizing with compost gave the highest values of yield and quality of carrot comparing with untreated plants in both studied seasons. 2-     Bio-fertilizing significantly increased yield and quality and the superiority was to the plants treated with bio-fertilizer mixture (Azotobacter, Bacillus circulans, Mycorrhiza) followed by EM. 3-     Fertilizing with 100% NPK has achieved the highest values of yield however, 75% NPK gave the highest values of carrot quality. 4-     The interaction among compost, bio-fertilizer (mixture or EM) and 100% NPK gave the highest values of yield however, compost plus bio fertilizer (Mixture or EM) and 75% NPK gave the superiority for yield and quality comparing with plants fertilizing with 100% NPK alone.
