Abstract: The present investigation entitled “Effect of different rooting hormone on cuttings of Pomegranate (Punica granatum) under protected condition in Prayagraj agro-climatic conditions” was conducted at shade net, Horticulture research farm, Department of horticulture, Naini agriculture college, SHUATS, Prayagraj (U.P.) during the academic year 2022-24. Plant growth hormones combination treatments include T0 (Control ), T1 (IBA @ 2000 ppm + PG @ 3000 ppm), T2 (IBA @ 2000 ppm + PG @ 4000 ppm), T3 (IBA @ 2000 ppm + PG @ 5000 ppm), T4 (IBA @ 2000 ppm + PG @ 6000 ppm), T5 (IBA @ 3000 ppm + PG @ 3000 ppm), T6 (IBA @ 3000 ppm + PG @ 4000 ppm), T7 (IBA @ 3000 ppm + PG @ 5000 ppm), T8 (IBA @ 3000 ppm + PG @ 6000 ppm) T9 (IBA @ 4000 ppm + PG @ 3000 ppm) T10(IBA @ 4000 ppm + PG @ 4000 ppm) T11 (IBA @ 4000 ppm + PG @ 5000 ppm) T12 (IBA @ 4000 ppm + PG @ 6000 ppm). The root, shoot parameters and survival percentage on transplanting of the cuttings of each treatment was done up to 90 days and all the observations were recorded at every 30 days interval. The root length (cm) and shoot length (cm) were recorded highest in the treatment T7 during research which were (15.08 cm) and (52.68 cm) respectively. Days of first shoot initiation and Days of first leaf initiation had increasing trend during research work and lowest days recorded (6.59) and (7.02) in T7 treatment respectively at 15 days. On the basis of our experimental findings, it is concluded that the T7 (IBA @ 3000 ppm + PG @ 5000 ppm) was found to be best in the terms of days to first shoot initiation, days to first leaf initiation, shoot lengths, number of leaves, number of new shoots, root lengths, fresh weight of roots, dry weight of roots. After the transplantation of the Pomegranate cuttings, T7 (IBA @ 3000 ppm + PG @ 5000 ppm) was found to be best in the terms of number of new shoots, shoot length, number of new leaves. In terms of rooting percentage and earliness of shooting, T7 (IBA @ 3000 ppm + PG @ 5000 ppm) was found to be best. The survivability or the establishment percentage found to be the highest in T7 (IBA @ 3000 ppm + PG @ 5000 ppm). It is also concluded that the best treatment of Pomegranate cuttings for Prayagraj agro-climatic conditions was found to be T7 (IBA @ 3000 ppm + PG @ 5000 ppm) for establishment.
