Abstract
The present investigation, “Effect of IBA, shoot thickness and growing media on the performance of pomegranate (Punica granatum L.) cuttings’’ were carried out in fruit nursery, Department of Fruit Science, College of Horticulture and Forestry Neri, Hamirpur (H.P.), during the year 2021- 2022. The research trial was conducted in pomegranate cv. Bhagwa and Kandhari Kabuli. The pomegranate cuttings were treated with different concentration of IBA (1500 ppm, 2000 ppm, 2500 ppm) having thickness i.e., 0.50-1.00 cm and >1.00 cm and planted in different growing media (perlite + vermiculite, cocopeat + perlite, cocopeat + vermiculite, cocopeat + vermiculite + perlite and sand + soil + FYM). Different vegetative growth parameters viz., time taken for bud sprouting (day), sprouting percentage (%), time taken for first leaf emergence (days), number of sprouts per cutting, number of shoots per cutting, length of sprouted shoots (cm), total number of leaves per cutting, plant height (cm), cutting diameter (cm) and survivability percent (%) were recorded. Similarly, root growth parameters viz., total length of root (cm), number of segments, number of forks, number of root tips, diameter of root (maximum), diameter of root (average), estimated volume of root (cm3) and rooting percent (%) of cuttings are also being recorded during this period. Among different
concentrations of rooting hormone, pomegranate cuttings treated IBA @ 2500 ppm resulted in maximum survival (86.95 and 86.32 %) and rooting per cent (80.84 and 80.03 %) whereas, cuttings having thickness >1.00 cm recorded maximum survival (85.74 and 85.11 %) and rooting percent (79.23 and 78.43 %). However, cuttings grown in mixture of perlite + vermiculite exhibited maximum survival (94.22 and 93.72 %) and rooting percent (89.72 and 88.83%), respectively in Bhagwa and Kandhari Kabuli cultivar.
