Abstract
A field experiment was conducted during the rabi 2017-2018 at Wheat Research Station, Junagadh Agricultural University, Junagadh to study the effects of NAA (Naphthalene Acetic Acid), GA3 and ascorbic acid on growth and morpho-physiological of wheat cv. GJW-463. The investigation was carried out in RBD with three replications and foliar application of different concentration of NAA, GA3 and ascorbic acid such as NAA (25,50, 75 ppm), GA3 (150, 250, 450 ppm) at 30 & 45 DAS and ascorbic acid (200, 300, 400 ppm) at 45 & 60 DAS. The experiment results revealed that foliar application of NAA, GA3 and ascorbic acid increased the plant height and flag leaf area was more in GA3 @ 150 ppm treated plants. Among different treatments, significantly higher LAI, CGR (g m-2 day-1), LAD (m2 m-2 day-1), NAR (mg cm2 day-1) and seed yield (kg ha-1) were observed in GA3@ 150 ppm treated plants as compared to control.
