Effect of plant growth regulators on growth and development of pomegranate (Punica granatum L.)

The present study was conducted to explore the effects of different plant growth regulators on the growth and development of pomegranate plants under randomized block design (RBD) having nine treatments replicated thrice with control. The study involved the application of two PGRs i.e., Naphthalene acetic acid (NAA) and Gibberellic acid (GA₃) at different concentrations namely 40 ppm, 50 ppm, 60 ppm and 100 ppm respectively. Parameters such as vegetative growth, flowering, fruit set, fruit quality, fruits chemical composition and yield attributes were assessed. The findings provide valuable insights into the potential of PGRs to enhance pomegranate productivity and overall plant performance. Growth and yield parameters of the crop were significantly influenced by the use of plant growth regulators. The foliar application of GA₃ 60 ppm showed maximum growth, yield and showed fruit quality improvement.
