Effect of Salinity Levels on Root and Shoot Growth of Brinjal Varieties Grafted on Solanum torvum

Abstract

A study was conducted to know the effect of different salinity levels on root and shoot attributes of brinjal varieties grafted on Solanum torvum under pot experiment and laid out in Factorial Randomized Block Design (FRBD) at College of Agriculture, Department of Horticulture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra) during the year 2020 and 2021. Experiment replicated twice with two factors, i.e., brinjal grafts at four levels (Phule Arjun, Phule Harit, Krishna and Manjari Gota grafted on Solanum torvum by cleft grafting method) and salinity levels at five levels (0/control, 2, 3, 4 and 5 dS m-1 were imposed with sodium chloride). Among the different varieties grafted on Solanum torvum Phule Harit showed significantly superior performance for shoot dry weight (129.83 g), primary roots (54.05), root fresh (139.67 g) and dry weight (67.33 g), root to shoot ratio (0.497). However, shoot fresh weight (463.45 g), secondary roots (2699.85) and root length (50.45 cm) were recorded in Phule Arjun. Among the different salinity levels, majority of the characters were noted to be significantly maximum in control (0.00 dS m-1). All together Phule Arjun and Phule Harit grafted on Solanum torvum was found significantly maximum values for majority parameters at heigher salinity levels (3.00 and 5.00 dS m-1). Phule Arjun and Phule Harit grafted onto Solanum torvum at salinity levels of 3.00, 4.00 and 5.00 dS m-1 was found significantly maximum values for different shoot and root parameters.
