Abstract

The present investigation entitled Evaluation of different dahlia (Dahlia variabilis L.) hybrids under Prayagraj Agro-Climatic Conditions was under taken in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during November, 2023 – May, 2024. The experiment was laid out in Randomized Block Design (RBD) with 15 hybrids replicated thrice. The hybrid V9 (D.S.I.) was found to be significantly better in terms of plant height (72.5 cm), number of leaves per plant (70.9), stem diameter (2.32 cm), branch length (39.47 cm), Days taken for the flower bud appearance (74.5 days), flower diameter (16.7 cm), Flower stalk length (18.6 cm), number of flower per plant (21.3) flower yield per ha (7.2 lakh), vase life (7 days), and self-life (12.9 days), duration of flowering (27.6 days), no of tubers per plant (8.3), tuber yield per plant (192.2 g/ha), Tuber yield per hectare (9.4 tonnes) and highest B:C ratio (2.15).
