Abstract:
The present investigation entitled “Effect of different varieties of scion and date of wedge grafting in Guava (Psidium guajava L.)” was carried out during 2022-23 at the shade net of Horticulture Research Farm, under Pt. Kishori Lal Shukla College of Horticulture and Research Station, Rajnandgaon, Chhattisgarh. The research was framed in Factorial Completely Randomized Design (FCRD) with 12 treatments which were replicated thrice. There were 2 factors, first factor with 6 levels of different date of wedge grafting viz, 10 September (D₁), 25 September (D₂), 10 October (D₃), 25 October (D₄), 10 November (D₅) and 25 November (D₆) and second factor with 2 levels of variety of scion i.e. Allahabad Safeda (V₁) and Lucknow-49 (V₂). The experiment was exempted to find out the effect of different date of wedge grafting and different varieties of scion on the success of guava grafts. The treatment combination D₁V₂ (10 September+Lucknow-49) was found superior for growth parameters viz, minimum number of days taken to bud sprouting (13.13 days), for first leaf opening (16.23 days), maximum number of sprouts (7.93), number of leaves (22.07), graft height (48.15 cm), rootstock girth (10.63 mm), scion girth (9.71 mm), leaf area (23.48 cm²), graft success (74.84%) and graft survival (70.00%).
