Floriculture is an essential branch of Horticulture concerned about growing and cultivating the flowers, foliage plants, and their marketing. It also deals with the production of planting materials through seedling, cutting, budding, and grafting. Polyhouse is a technology for flowers and vegetable cultivation through which farmers can get high and quality production and benefits. So, a study was planned for finding the quality of rose flowers in open cultivation and different polyhouses. The research was carried out in two different types of polyhouses and an open area. It was found that all the environment parameters, i.e., light, temperature, humidity, and CO2, were significantly higher in NVPH type of polyhouse compared to AISNH and open cultivation. Except for the diameter of rose flowers, all the other parameters of quality of flowers i.e., color, the height of flowers, a diameter of flowers and spikes etc., were higher in NVPH and AISNH than in the open cultivation.

Highlights

• Significant differences were found among all the environmental parameters, i.e. light, temperature, humidity, and CO2 level, in different cultivation units.
• Except diameter of rose flowers, all the quality parameters were higher in roses grown NVPH type of polyhouse.
