Abstract: A pot experiment was performed according to a factorial randomized design at Aligarh to study the effect of 4 levels of gibberellic acid spray (0, 10-8, 10-6 and 10-4 M GA3) on the growth, leaf-NPK content, yield and quality parameters of 2 tomato cultivars (Lycopersicon esculentum Mill.), namely Hyb-SC-3 and Hyb-Himalata. Irrespective of its concentration, spray of gibberellic acid proved beneficial for most parameters, especially in the case of Hyb-SC-3.

Keywords: Tomato cultivars, GA3 spray, growth, leaf-NPK, yield and quality characteristics
