In this experiment, investigation on paclobutrazol concentration (PBZ) to growth of pearl millet in pot plants and completely randomized design was designed and conducted into 6 treatments including control (PBZ 0), 50, 100, 150, 200 and 250 mgL^-1 with 10 replications. The results founded that high concentration of PBZ showed the inverse variation with growth of pearl millet in pot plants. For PBZ0 gave the height, leaf length, flower stalk length and flower length at week 6 are 60.78, 20.94, 23.89 and 12.64 cm, respectively. The average of flower fresh weight per plant, dry weight per plant and dry weight only flower per plant at week 6 are 80.64, 17.77, 5.58 grams, respectively.
