Performance of Grafted Tomato for Horticultural and Quality Traits under Polyhouse Conditions

Abstract

Present investigation was carried out for two successive years i.e. 2016-17 and 2017-18 to study the performance of grafted tomato with respect to growth, yield and quality of tomato under polyhouse conditions at Department of Vegetable Science and Floriculture, CSKHPKV, Palampur. Sixteen different rootstocks of tomato were grafted with scion cultivar 'GS-600'. The experiment was laid out in a Randomized Block Design with three replications and cleft grafting method was used. Plants grafted on rootstock LS-89 proved superior to other rootstocks for days to first flowering and days to first harvest. For prolonged harvest duration plants grafted on tomato rootstock Green Gourd found superior. Higher yield in terms of number of marketable fruits per plant, marketable fruit yield per plant and marketable fruit yield per square metre in were recorded plants grafted on tomato rootstock Green Gourd.
