Two field experiments were conducted at the private farm in El-Mataryia region, Dakahlia Governorate during 2004/2005 and 2005/2006 seasons to study the effect of Gibberellic acid (GA₃), chemical and organic fertilization on vegetative growth, yield and its components, of garlic crop. The split plot design with three replications was used. The main obtained results could be summarized as follows: GA₃ application at 10 ppm caused significant increases on plant height, number of leaves/plant, plant leaf area, fresh weight of plant, dry weight of plant, total chlorophyll, neck diameter, bulb diameter, total yield of garlic (t/fed), bulb diameter, bulb weight, number of cloves/bulb and clove weight in both seasons as well as bulbing ratio in the second season only. All studied characters of this study were significantly increased by using 100 % chemical fertilizers (CF) and 50 % CF + 50 % FYM treatments in both seasons. Also, there were not significant differences between using 100 % CF and 50 % CF + 50 % FYM treatments in both seasons. The interaction between GA₃ application and fertilization treatments had a significant effect on total yield of garlic, bulb diameter in both seasons. The highest values of these characters were resulted from using 100 % CF with GA₃ application and 50 % CF + 50 % FYM treatments with application of GA₃ without significant differences between them in both seasons.
