This research deals with the effects of plant growth regulators on groundnut growth (Arachis hypogaea L. cv. Tatu-53). Plants of groundnut with four leaves grown in pots under greenhouse conditions, were sprayed with chlormequat 2000 ppm, daminozide 4000 ppm, gibberellic acid 100 ppm, indolylacetic acid 100 ppm, mid check treatment. Daminozide 4000 ppm reduced plant height, internode number and the length of the fourth internode. Daminozide increased the number of leaves, retarded flowering, increased the number of flowers and presented a tendency to increase the dry weight of stems. Chlormequat 2000 ppm and indolylacetic acid 100 ppm reduced plant height and the lenght of the fourth internode of the groundnut plant stem.
