The field experiment to study the effect of plant growth
regulators on growth and yield parameters of radish (Raphanus sativus L.) was
conducted during the year 2017-2018 at Horticulture Research farm, Department
of Horticulture, CCS Univ. Campus, Meerut (U.P) India. There were nine treatments
i.e. T1 (GA3 @ 50 ppm), T2 (GA3@ 100 ppm), T3
(IAA @ 50 ppm), T4 (IAA @ 100 ppm), T5 (NAA @ 50 ppm), T6
(NAA @ 100 ppm), T7 (MH @ 100 ppm), T8 (MH @ 200 ppm) and T9 (control). The
findings of the present investigation clearly indicated that the foliar
application of GA3@100 ppm gave significant effect to improved growth and yield
parameters of radish viz., plant height (36.93 cm), number of leaves (25.79),
leaf length (33.60 cm), root diameter (5.39 cm), weight of root (250.66 g) and
yield (380.94 q/ha) as compared to other treatments. Hence, foliar application
of GA3 @ 100ppm may be suggested for getting maximum vegetative growth and
yield of radish under Western Uttar Pradesh conditions.
