Reduction in Yield and Market Quality of Celery Caused by Soil Salinity1

Abstract
The effect of soil salinity on yield and market quality parameters of celery [Apium graveolens L. var. dulce (Mill.) Pers.] was determined in field plots. Saline treatments were imposed by irrigating with water that contained NaCl and CaCl2 in equal concentrations. Celery was found to be moderately sensitive to salinity. Relative yield was reduced 6.2% for each unit increase in soil salinity beyond 1.8 dS/m (dS/m = mmho/cm, referenced at 25°C). Petiole length, width, and thickness were also significantly reduced with increasing salinity. Salinity had no effect on pith development.
