THE EFFECT OF DIFFERENT LEVELS OF GIBBERELLIC ACID ON THE GROWTH AND YIELD OF RADISH (Raphanus sativus.)

The pot experiment was conducted at Mindanao State University Campus General Santos City from November to December 2016. This was undertaken to evaluate the growth and yield response of radish to different levels of gibberellic acid on the radish. The experiment was carried out using a completely Randomized Design (CRD) with the four treatments replicated four times. The levels of gibberellic acid which served as the treatments were the following: T1- control; T2- 25 ppm; T3- 50 ppm; and T4-100 ppm. In this study, The GA application rates seemed to be not appropriate for radish. Lower levels of application needs to be explored. Similar studies may be evaluated also in other crops.
