Abstract:
An experiment to investigate “growth and flowering of chrysanthemum in hydroponics” was conducted at Assam Agricultural University, Department of Horticulture. The experiment was laid out factorial completely randomized design with three replications. In this Experiment chrysanthemum plants were grown in seven different growing media combinations viz. M1: coco peat, M2: coarse sand, M3: cinder, M4: coarse sand cinder (1:1 v/v), M5: coarse sand and coco peat (1:1 v/v), M6: coco peat and cinder (1:1 v/v) and M7: coco peat, coarse sand and cinder (1:1:1 v/v) and 2 different concentrations of nutrient solution (modified Hoagland solution) viz. N1: EC 1.5 dS/m and N2: EC 1.8 dS/m. The results revealed that soilless growing media and concentration of nutrient solution significantly influenced the growth and flowering of chrysanthemum cv. “Rajkumari”. Among the growing media, coco peat+ cinder was found significantly superior to all other growing media and among the nutrient solution concentrations, EC 1.8 dS/m was found superior to EC 1.5 dS/m in terms of growth of the plants and quality flower production. Thus, from the floriculture perspective it can be concluded that growing media coco peat+ cinder with EC 1.8 dS/m is suitable for chrysanthemum production.
