Response of gibberellic acid on growth and yield of radish (Raphanus sativus L.) Cv. Japanese white

Abstract

In order to study the response of Gibberellic acid on growth and yield of radish the field experiment was conducted in the year 2010 at Experimental field of Department of Horticulture, College of Agriculture, Gwalior. Observations were recorded on ten yield and yield attributing characters viz., plant height (cm), plant spread (cm), number of leaves/plant, leaf length (cm), fresh weight of leaves/plant (g), root girth (cm),root length (cm), fresh weight of root (g), dry weight of root (g) and yield (q/ha.). Five concentrations of gibberellic acid (10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 pp) along with control were applied on radish and it was concluded that GA3 sprayed at 50 ppm resulted in significantly increased numbers of leaves/plant, leaf length, fresh weight and dry weight of leaves, and root yield.
