The cut flower sector in Oman is no less important than the rest of the agricultural sectors, but unfortunately, there is no or very little research so far on this sector has been conducted. Therefore, this study was initiated to evaluate the growth and yield performance of two species of commercial cut flowers (geranium and carnation) under contrasting growing conditions. During this research study, three different sets of experiments were performed. The first experiment was the cultivation of two types of cut flowers geranium and carnation in two contrasting environments, an airconditioned greenhouse equipped with artificial lighting, and a traditional evaporative cooling system greenhouse with natural lighting. In this experiment, two types of irrigation water were used, freshwater and tertiary treated wastewater. The experiment data was collected at two stages, the vegetative growth stage, and the flowering stage. During the experiment, the required data were collected on the effect of water type and the nature of the agricultural growing environment on plant morphology, physiology, and flowering. It is concluded that the traditional evaporative cooling system greenhouse was the best in the cultivation of cut flowers and there were no statistically significant differences recorded between the types of water used. The second experiment was using cut flowers from the first experiment to find out the vase life longevity of the flowers when placed in a container with some preservative solutions. Two different solutions with three different concentrations were used. The first solution was the moringa leaf extract at concentrations of 30, 60, and 90%, and the second solution was boric acid at concentrations of 50, 100, and 150 mg L-1 . It is concluded that the Indian Shua (moringa) solution with a concentration of 30 percent was the best, and the boric acid solution at a concentration of 100 mg L-1 performed better compared to other treatments. The third experiment was based on a questionnaire-based survey conducted throughout the Sultanate of Oman, examining the extent of citizens' desire to buy cut flowers for various occasions. A total of 907 responses were collected and it showed that 80% of the respondents were willing to buy cut the flowers. In conclusion, the cut flowers can be grown in Oman with high demand, and with the use of particularly traditional evaporative greenhouses conditions and treated wastewater.
