PHENOLOGY OF RADISH (RAPHANUS SATIVUS L.) VAR. PUSA CHETKI AS AFFECTED BY SEED PRIMING OF PLANT GROWTH REGULATORS (GA3, NAA, IAA AND SA)Lalit Kumar, Beena Singh, D. Khokhar and Rajshree GayenAbstract The present investigation was carried out at S.G.College of Agriculture and Research Station, Jagdalpur, Bastar (C.G.) during Rabi season of 2022. The experiment was laid out in randomized block design with three replications and thirteen treatments comprising of GA3 (5,10 and 15 ppm), NAA (10, 20 and 30 ppm), IAA (20, 25 and 30 ppm), Salicylic acid (15, 30 and 45 ppm) and control (no growth regulator) to improve various growth and yield contributing parameters of radish. The result revealed highest days to 50% germination (5.33 days), plant height (35.95 cm), root length of plant (24.40 cm), root diameter (3.73 cm), fresh weight of root (133.51 g), dry weight of root (18.41 g), root yield (24.38 t ha-1), TSS (5.53 °Brix) and antioxidants (21.14 mg/100g-1) with the pre-treatment of GA3 15 ppm. |
