Abstract:
An experiment entitled “Economics of chrysanthemum cultivation at different levels of light interruption.” was conducted at Nursery No. 10, College of Horticulture, Dapoli, Dist. Ratnagiri during the year 2020-2021. The experiment was laid out in randomized block design with three replications and eight treatments along with control. During the period of research all parameters were significantly influenced by different levels of light interruption/dark exposure in Chrysanthemum cv. Chandrika. Vegetative, flowering and yield parameters like maximum fresh and dry weight for plant, root and shoot, shoot: root ratio (fresh and dry weight), number of flower buds/polytunnel, number of flowers/polytunnel, yield of flowers/polytunnel, yield of flowers/ha and benefit cost ratio (economics) accordingly all these observation parameters mentioned above were found promising in treatment (T₆) i.e., 180 minutes level of light interruption using 90% black shade net in chrysanthemum cv. Chandrika under polytunnel condition while average illuminance of light was recorded at 15 days interval under uniform conditions inside polytunnel which was non-significant.
