Abstract:
The study was carried out during the year 2021-22 under normal poly house condition at department of fruit science, College of Horticulture, Mudigere, on Effect of Growth Stimulants on Growth and Survivability of Avocado (Persea americana Mill.) Grafts under Hill Zone of Karnataka. Experiment was laid out in Completely Randomized Design with seven treatments, replicated thrice. In this experiment, avocado grafts were sprayed with GA₃, Biovita and Vipul at different concentrations. GA₃@ 200 ppm recorded maximum graft height (43.72 cm), sprout length (12.73 cm), number of sprouts (7.48), number of leaves (19.68), graft percentage (86.17), graft survival percentage (82.74) and graft vigour index II (3259.59 cm). Grafts sprayed with Biovita @ 4 ml per litre recorded maximum sprout diameter (2.68 mm). Grafts sprayed with Vipul @ 5 ml per litre recorded maximum graft vigour index I (793.37 cm).
