The aim of this work wasto evaluate the application of commercial products containing giberelic acid in their compositions on production of alfalfa sprouts crioulacultivar. The experimental design was completely randomized factorial 2 x 5, with 5 GA3 doses being 0, 100, 200, 300 and 400 mg L-1 and two products: PROGIB® and Stimulate®. The treatment of alfalfa seeds with commercial product Stimulate® is recommended in lower doses than 100 mg L-1. The dose of 400 mg L-1 of ProGib® showed the highest values of biometrics parameters for sprouts alfalfa tested in this work. The ProGib® commercial product showed better performance when compared to Stimulate®.
