Abstract:
The experiment entitled “Studies on the grafting success of brinjal (Solanum melongena L.) On different rootstocks” was carried out at Hi-tech Unit, College of Horticulture, Dapoli, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. – Ratnagiri (M.S.) during year 2020-21 and 2021-22 with nine treatment combinations and four replications under Factorial Randomized Block Design (FRBD). The factor 1 was Rootstocks: R₁-Konkan Prabha, R₂-Arka Neelkanth and R₃-Solanum torvum. Factor 2 was Scions (F₁ hybrids): S₁-NBH-1465, S_2-Manjari and S₃-Utkarsha. The grafting was done using splice method with the help of silicon grafting clips of size 1.7 mm and 1.9 mm. The girth of rootstock at collar during grafting exhibited the significant effect and the maximum girth registered in rootstock R₃ (2.46 mm) whereas it was minimum in rootstock R₁ (2.15 mm). The girth of scion at collar during grafting was found non-significant and was in range of 2.37 mm (S₂) to 2.41 mm (S₃). The effect of rootstock on the graft survival at 21 DAG was found significant and highest grafting survival was recorded in R₁ (82.64%) which was at par with R₂ (82.60%) while the lowest was recorded in R₃ (78.57%). However, the effect of scion and interaction effect on grafting survival were non-significant. The effect of rootstock on tap root length was significant and maximum length was recorded in R₃ (20.46 cm) whereas effect of scion and interaction effect on the tap root length were non-significant.
