Abstract
Two field experiments were conducted during the two successive winter seasons of 2009/2010 and 2010/2011 in a private farm at Bani-Ebad near Deckernis canter, Dakahlia Governorate to study the effect of mineral, organic, bio-fertilization and their interaction on growth characters of carrot (Daucus carota L.). cv. shantenay. In general, it can be concluded that:
The highest values of leaf length, number of leaves/plant, root length, fresh weight of leaves and dry matter % were obtained as a result of trilateral interaction (compost plus bio-fertilizer mixture and 100% NPK). Meanwhile triple interaction compost plus EM and 100% NPK occupied the second order. The lowest value in this case obtained from application of 50% NPK alone.
The highest values of shoot/ root ratio were recorded when plants treated with compost plus bio-fertilizer mixture and 75%NPK followed by plants treated with compost plus bio-fertilizer mixture and 100%NPK after 120 days from sowing date in both seasons.
