This investigation was carried out on the variety Florence of sweet fennel to throw light on the growth and yield of growing plants to efficiency to tolerate different salinity levels in irrigation water. This experiment was designed to irrigate plants with three concentrations of saline drainage water, which were 1000, 2000 and 3000 ppm in addition to, the control one which received only tap water. Data were recorded on the physical and chemical characteristics of five plants ages representing 30, 60, 90, 120 and 150 days from seed sowing. The great significant tallest plants, number of leaves/plant, plant fresh weight, bulb fresh weight, bulb size and bulb perimeter during the various development stages were obtained from irrigation with saline water at the concentration of 2000 ppm. While, the least number was exerted from the highest concentration of 3000 ppm. Bulb acidity, phosphorus, potassium, oil and dry matter contents were not si gnificantly affected by the increase of different salinity levels in all the tested ages. Bulb carotenaids content significantly increased with the increase in salinity concentrations from 1000 to 3000 ppm in all the examined ages from 90 to 150 days.
