Abstract:
The research work entitled with “studies on effect of different concentrations of growth regulators on rooting of air layering in pomegranate (Punica granatum L.) Var. Super Bhagwa in Chhattisgarh plain” was conducted at experimental field PFDC (Precision Farming Development Centre), Department of Fruit Science, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (CG), during September 2021- January 2022. The experiment was laid out in a randomized block design with 9 treatments of different concentration of plant growth regulators i.e. IBA (Indole Butyric Acid) and NAA (Napthalene Acetic Acid). The pomegranate propagation significantly influenced by root parameters like days taken to start root initiation (19.87), rooting per cent (93.34%), length of roots (14.83cm), diameter of roots (1.08mm), number of roots (45.6), fresh root weight (0.77g), dry root weight (0.39g). Results revealed that growth regulator IBA concentration 2500ppm (T₄) has found better effect on rooting percentage of pomegranate followed by IBA concentration 2000ppm (T₃) and NAA concentration 2500ppm (T₈).
