Abstract
The present investigation entitled “Propagation studies in Fig (Ficus carica L.) under Jammu Sub-Tropics” was carried out in the year 2018-19, at the Research Farm, Division of Fruit Science, FoA Chatha, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu. Hardwood cuttings of fig (Ficus carica L.) cv. Brown Turkey were made from 5year old plant. These cuttings were treated with various concentrations of Indole -3-butyric acid (IBA) viz. 500, 1000, 1500, 2500, 3500, 4500 ppm and cuttings which were not treated with IBA were taken as Control. These IBA treated hardwood cuttings of fig were planted at different intervals of time i.e 1st January, 15th January, 1st February and 15th February and data were collected at 30, 60 and 90 days after planting of cutting. Results of the present study revealed that hardwood cuttings of fig treated with IBA 3500 ppm and planted in 1st February i.e T15 showed better of maximum number of sprouted cutting (4.99, 11.49 and 15.33at 30, 60 & 90 days after planting respectively) sprouting percentage (25.07, 57.58 &76.66 respectively), number of shoots per cutting (5.40 and 5.89at 60 & 90 days after planting, respectively), length of longest shoot, (8.48 and 16.72 cm respectively), longest shoot diameter (5.78 and 11.91 mm respectively), fresh weight of shoot (26.49 and 51.50 g respectively), dry weight of shoot (9.63 and 19.53 g respectively), number of leaves per cutting (11.16 and 13.14at 60 & 90 days after planting respectively), leaf area (230.40 and 294.77 cm2respectively), fresh weight of leaves (41.49 and 55.98 g respectively), dry weight of leaves (24.19 and 32.53 g respectively), content of chlorophyll (SPAD-value) (41.49 and 55.98 respectively) and maximum number of roots per cutting (25.50, 32.00 and 35.16at 30, 60 & 90 days after planting, respectively), diameter of longest root (1.21, 1.87 and 2.19 mm respectively), length of longest root (15.83, 26.11 and 29.24 cm respectively), fresh weight of root (0.91, 1.51 and 1.89 g respectively) dry weight of root (0.53, 0.64 and 0.70 g respectively) and highest survival percentage (70.43 %) was also recorded in same cuttings after 90 days was followed cuttings treated with 4500 ppm planted on 1st February .
From the present investigation it was concluded that cuttings treated with 3500 ppm IBA and planted on 1st February (T15) resulted in maximum number of sprouted cutting, sprouting percentage, number of shoots per cutting, length of longest shoot and root, diameter of longest shoot and root, fresh and dry weight of shoot, root, leaves, number of roots per cutting, leaf area, content of chlorophyll (SPAD-value), number of leaves per cutting, highest survival percentage
