Effect of Different Salinity Levels on Grafting Attributes of Brinjal Varieties Grafted on Solanum torvum

Aims: To know the effect of different salinity levels on grafting attributes of brinjal varieties grafted on Solanum torvum Study Design: The pot experiment was laid out in Factorial Randomized Block Design (FRBD). Place and Duration of Study: The current experiment was conducted at College of Agriculture, Department of Horticulture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra) during the year 2020 and 2021. Methodology: Experiment was replicated twice with two factors, i.e., first factor is grafts with four levels (Phule Arjun, Phule Harit, Krishna and Manjari Gota cleft grafted on Solanum torvum), and second factor is salinity gradients with five levels (0/control, 2, 3, 4 and 5 dS m-1) of sodium chloride (NaCl) salt to assess the response of rootstock towards the grafting parameters under salinity stress conditions. Results: Among the different varieties grafted on Solanum torvum, Phule Harit showed significantly superior performance for diameter of scion and scion to stock ratio. However, maximum diameter of the rootstock and scion was recorded in Phule Arjun and Phule Harit. In interactions, Phule Harit grafted on Solanum torvum was found maximum for scion diameter and scion to stock ratio at 3.00, 4.00 and 5.00 dS m-1. While, rootstock diameter was reported maximum in same graft at 4.00 and 5.00 dS m-1. All the brinjal varieties grafted onto Solanum torvum showed the highest survival percentage (98.75%) in the control as well as at 2 dS m⁻¹. Conclusion: Phule Arjun grafted onto Solanum torvum performed best, particularly under moderate salinity levels (3 dS m⁻¹) in different parameters.
