The agricultural sector is the main consumer of water and the optimal use and increase of water productivity in this sector will have a significant impact in maintaining it. In recent years, due to the lack of water, the diversity of people, and high incomes of cultivated ornamental flowering plants, the activity in the production of off-season flowers in the greenhouse has increased significantly. The aim of this study was to determine the water requirement and crop coefficients of lily (Lilium sp), Fanjio variety, under greenhouse conditions. For this purpose, a two-year experiment (2015 and 2016) was carried out and data recording was done. The modified lilies bulbs and grass seed were cultured in micro-lysimeters with a diameter of 0.2 m and a height of 0.5 m in the research greenhouse of the Faculty of Agricultural Sciences, University of Guilan. The amount of daily evapotranspiration of this plant was measured by weighing method in micro-lysimeters. The results showed that the total evapotranspiration of lily flower was 59 mm, the average of two years. Daily evapotranspiration of lily flower during the growth period was between 0.2 and 2.4 mm. The average vegetation coefficient of lily flower for two years was between 0.3 and 0.71 based on the reference plant i.e. grass in the greenhouse.
