Effect of plant growth regulators on vegetative growth and leaf yield of radish (Raphanus sativus L.) var. Kashi Ardra in Chhattisgarh plain

The present study entitled “Effect of plant growth regulators on vegetative growth and leaf yield 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 at vegetative character like maximum plant height (41.93 cm), number of leaves per plant (15.53), leaf length (39.27 cm), Leaf yield per plot (8.19 kg) and maximum leaf yield per ha (25.27 t). Hence, the treatment T3 (GA3 200 ppm) was found to be most suitable for higher production of radish.
