Abstract
The experiment was carried out to evaluate the rootstocks effect on growth, yield related quality parameters of different tomato hybrids. It conducted in Randomized Block Design (RBD) with twelve treatments and three replications. It consists two rootstocks viz., Solanum pimpinellifolium and Solanum lycopersicum cv. Arka Vikas, four hybrids viz., ‘Phule Raja’, ‘Arka Rakshak’,‘Arka Abhed’and ‘NS501’as scion and non-grafted tomato plants as controls. The scions were grafted on rootstocks using the cleft grafting method. The results depicted that the rootstocks S. pimpinellifolium and ‘Arka Vikas’ significantly improved the growth, yield and quality characteristic of tomato hybrids over controls. Results showed that S. pimpinellifolium and ‘Arka Vikas’ increased the fruit yield per plant by 33.15% and 20.10% over the controls, respectively. The environmental factor of soil such as moisture content, temperature and relative humidity was 10 to 12.5%, 28.5 to 32.5°C and 60 to 65%, respectively. The rootstock S. pimpinellifolium exhibited superiority over the rootstock ‘Arka Vikas’ for most of the parameters. Grafted plants were found better than non-grafted for height of the plant, primary branches/plant, equatorial diameter, polar diameter, pericarp thickness, number of fruit/plant, average fruit weight, yield fruit, titratable acidity and total soluble solids.
