Performance of tomato cultivars for polyhouse cultivation during spring summer in Assam

A study was carried to evaluate 27 tomato cultivars in relation to growth, yield and quality under plastic rainshelter during summer season. Out of all the 27 cultivars, Yash recorded the maximum yield of 1.76 kg per plant followed by Arka Ahuti and Arka Ashish. Yash also recorded the maximum plant height, branch number, fruit set percentage and yield per plant.The flowers per inflorescence were found highest in cultivar BT₁. On the other hand, Arka Ahuti recorded the highest retention of matured fruits. Regarding the quality parameters, no single cultivar was found to be excellent in all the qualitative parameters. A wide range of variation was observed in both physical and chemical constituents of the fruits. However, Pusa Ruby and Arka Shreshta recorded the maximum TSS content, whereas the maximum amount of ascorbic acid was recorded in DRD-8014.
