Performance of South Indian Chrysanthemum (Dendranthema grandiflora T.) Varieties Under High Density Planting in Prayagraj Climatic Conditions

A field experiment was conducted to evaluate the response of south Indian chrysanthemum (Dendranthema grandiflora T.) varieties under high-density planting in Prayagraj climatic conditions at the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during the period of October, 2022 to January, 2023. The experiment was laid out in Factorial Randomized Block Design (FRBD) comparing two factors with twelve treatment combinations in three replications. Significant improvement in growth and flowering characters was recorded in T8(Poornima White with spacing of 30 cm x 10 cm, 47.5 cm) was found to be tallest in plant height, T5(Poornima White with spacing of 30 cm x 30 cm) recorded wider in plant spread (42.6 cm2), more the number of primary branches (15.7), greater the number of flowers per plant (23.9), bigger size of flower diameter (7.6 cm) and longer shelf life of the flower (8.5), T12(Belgium Pink with spacing of 30 cm x 10 cm) found best in parameters i.e., less number of days taken to first flower bud initiation (43 days), and days taken to 50 percent flowering (73 days).
