Abstract:
The following investigation entitled “Studies on propagation of phalsa (Grewia subinaequalis DC.) by cuttings’’ was carried out during July - November 2019 at College Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat. Experiment was conducted in completely randomized design with three replications. Total thirteen treatments were studied in the following investigation. The following investigation carried out under two growing conditions from which propagation chamber performed significantly superior as compare to shade net house with respect to shoot parameters as days taken for first sprout to appear (7.73), number of leaves per cutting (5.81, 9.76, 11.77 and 15.37), mortality percentage (36.11, 42.22, 47.78 and 50.00%), survival percentage (63.89, 57.77, 52.22 and 50.00%) and shoot length (6.18, 11.63, 18.36 and 21.83 cm) at 30, 60, 90 and 120 DAP, respectively. Among different plant growth regulator treatments, NAA 1500 was found significantly superior with respect to shoot parameters such as days taken for first sprout to appear (6.73), number of leaves per cutting (7.17, 12.07, 13.87 and 16.90), mortality percentage (22.78, 33.89, 38.89 and 38.89%), survival percentage (77.22, 66.11, 61.11 and 61.11%), and shoot length (7.40, 13.80, 20.17 and 24.10 cm) at 30, 60, 90 and 120 DAP respectively. The interaction between propagation chamber condition and NAA 1500 ppm concentration was found superior with respect to shoot parameters such as days taken for first sprout to appear (6.60) and number of leaves per cutting (7.33, 14.00 and 17.00) at 30, 90 and 120 DAP, respectively, while mortality percentage (33.33, 36.36 and 36.36%) and survival percentage (66.66, 63.63 and 63.33%) at 60, 90 and 120 DAP, respectively. It also found superior in shoot length (7.60, 14.13, 20.40 and 24.40 cm) at 30, 60, 90 and 120 DAP.
