Abstract:
The present investigation entitled “Standardization of grafting time and various environmental conditions in jamun (Syzygium cumini Skeels)” was carried out at Hi-Tech Horticulture Park, Department of Horticulture, Junagadh Agricultural University, Junagadh during the year 2020-21. The treatments comprised of nine level of grafting time (G) viz., G₁ = 16^th January, G₂ = 1^st February, G₃ = 16^th February, G₄ = 1^st March, G₅ = 16^th March, G₆ = 1^st April, G₇ = 16^th April, G₈ = 1^st May, G₉ = 16^th May and three level of various environmental conditions (E) viz., E₁ = Open field, E₂ = Net house, E₃ = Polyhouse. The experiment was laid out in Completely Randomized Design (CRD) with Factorial concept comprising twenty seven treatments combinations with three replications. The result indicated that among nine grafting treatment, G₄ (1^st March) gave minimum days required for emergence of sprout (17.67), success rate (58.33%) at 30 DAG with minimum mortality (51.11%) and maximum survival (48.89%) at 120 DAG. Among three environmental conditions, E₃ (Polyhouse) gave minimum days required for emergence for sprout (19.03), success rate (47.96%) at 30 DAG with minimum mortality (61.11%) and maximum survival (38.89%) at 120 DAG.
