Pruning and Gibberellic Acid on the Growth and Yield Attributes of Onion (Allium cepa L.) var Agrifond Light Red

Abstract

A Field trial was carried out at Horticulture Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, to assess the effect of pruning, Gibberellic acid and methods of application on growth and yield components were carried out on onion. Out of 19 treatment combinations comprised of three level of pruning, six levels of GA at different concentration and its methods of application viz., pruning (leaf pruning, root pruning, leaf and root pruning), GA (50, 100, 150 ppm and method viz., root dip, foliar spray). The growth and yield attributing character were significantly differed due to different level of pruning and Gibberellic acid. The interaction effect of Leaf pruning along with GA 150 ppm as foliar spray was effective in maximum plant height, number of leaves per plant, weight of bulb, dry weight of bulb, yield (kg/plot) while the minimum plant height, number of leaves per plant, weight of bulb, dry weight of bulb, yield (kg/plot) from control i.e. without leaf and root pruning and no GA control treatment.
