Abstract

In order to ascertain the assessment of performance of foliar application of NAA and GA3 on growth and yield attributes of Onion (Allium cepa. L).  A field trial was conducted at the Horticultural Research Farm of Baba Farid Institute of Technology (BFIT), Dehradun, India, 2021–2022. Significant differences in results were observed. With nine treatments and three replications of each growth regulator—NAA and GA3—at various levels (50, 100, 150, and 200 parts per million—the research was set up in a Randomized Complete block design. The superior growth attributes like maximum plant height (47.38 cm) at 45 DAT, (51.01 cm) at 60 DAT and (54.04 cm) at 90 DAT, maximum number of leaves per plant (6.32) at 45 DAT and (8.84) at 60 DAT were recorded from the application of NAA 150 PPM (T3). The superior yield attributes like highest fresh weight of bulb per plant (60.12 gm), bulb polar distance (4.75 cm) and bulb equatorial distance (5.45 cm) were recorded from the application of GA3 100 PPM (T6).

Keywords: Onion, NAA, GA3, growth, yield
