Effect of plant growth regulators on root yield and quality of Radish (Raphanus sativus L.) var. Kashi Ardra in Chhattisgarh plain

Abstract

The present study entitled “Effect of plant growth regulators on root, yield and quality of Radish (Raphanus sativus L.) var. Kashi Ardra in Chhattisgarh plain.” was carried out during Rabi season 2023-24 in the Pt. K.L.S. College of Horticulture and Research Station, Rajnandgaon (C.G.). The field experiment was laid out in Randomized Block Design with three replications and thirteen treatments consisting a control viz. (T0) Control (Water spray), (T1) GA3 @ 100 ppm, (T2) GA3 @ 150 ppm, (T3) GA3 @ 200 ppm, (T4) IAA @ 50 ppm, (T5) IAA @ 100 ppm, (T6) IAA @ 150 ppm, (T7) NAA @ 100 ppm, (T8) NAA @ 150 ppm, (T9) NAA @ 200 ppm, (T10) IBA @ 50 ppm, (T11) IBA @ 100 ppm, (T12) IBA @ 150 ppm. The finding of the present investigation clearly indicated that the foliar application of GA3 200 ppm gave significantly better performance in root yield and quality attributing character like maximum root length (23.96 cm), maximum root diameter (4.66 cm), fresh weight of the root (136.33 g), root yield per plot (9.81 kg), root yield per ha (30.26 t) and quality parameter like maximum TSS (5.50 °Brix) and maximum ascorbic acid (21.40 mg/100 g). Hence, the treatment T3 (GA3 200 ppm) was found to be most suitable for higher production of radish.
