What is the polyhouse cost and yield for exotic chrysanthemum cut flower per unit area?

Cut chrysanthemum can be grown under a polyhouse or a simpler net house with black out and lighting arrangement, so the structure cost is in the broad protected cultivation range of about Rs 700 to Rs 1100 per square metre for a good house, with a net house and black out setup sometimes cheaper than a full fan and pad polyhouse. Planting is fairly dense and you get straight stems, with standard types giving one big disbudded bloom per stem and spray types several blooms per stem, so stem and bloom yield per square metre depends on which you grow and your density. The yield per unit area is a range to verify locally. The extra cost over an open crop is the lighting and black out cloth needed to control flowering time, but that control is what lets you hit festival and wedding dates and earn the premium. Confirm density, expected yield and the black out and lighting setup cost with your KVK or a grower before budgeting.
