Effect of planting dates and photoperiod on growth and flowering of chrysanthemum (Chrysanthemum morifolium Ramat) cv. yellow Reagan

Rooted cuttings of chrysanthemum (Chrysanthemum morifolium Ramat.) cv. Yellow Reagan were planted in different planting dates and treated with two different photoperiod. The experiment was carried out with nine treatments in Completely Randomized Design with three replications. The vegetative growth, flowering, flower yield and flower quality parameters were recorded. The results of present investigation treatment T5-1st June (16 hours dark and 8 hours daylight) recorded higher plant height (63.63 cm) and maximum number of flowers per spray (5.33). Early flowering (41.33 days) was obtained in T9-1st December (Natural photoperiod). Maximum number of side shoots per plant (11.00) and number of flowers per plant (42.33) were recorded in treatment T6-1st June (14 hours dark and 10 hours daylight). Maximum number of flowers per spray (5.33), duration of flowering (26.00 days), size of the flower (5.93 cm) and weight of flower (2.77 gm) were noticed in treatments T7-1st August (Natural photoperiod).
