Water scarcity and soil salinity are two important limiting factors for agricultural production. Canola crop, with high resistance to soil salinity and adaptation to different climatic conditions of Iran, has great ability for satisfying the main part of the country’s requirements for edible oil. This research was carried out in 2006 on winter canola (Brassica napus L., cv. Zarfam) under greenhouse condition at the Agriculture and Natural Resources Research Center, Yazd. The experiment was performed as a complete randomized block design with three replications that contained salinity and irrigation water factors. Salinity factor had four levels of S1=3-4, S2=6-7, S3=9-10 and S4=12-13 dS/m and irrigation water factor had three levels of irrigation after W1=30, W2=50 and W3=80 percent of management allowed moisture depletion. Soil texture was sandy loam. The results showed that salinity and deficit irrigation were significantly effective on dry matter production (p
