The field experiment was carried out at the Dardanos Agricultural Research Station of Canakkale Onsekiz Mart University in 2015, near Dardanelles straits in Canakkale province, Turkey. Irrigation interval (4-day) was fixed for all treatments and evaporation was determined by Class-A pan. In the full treatment (I1.0), water in the root zone was refilled according to the amount of water evaporated from Class-A pan. In the deficit treatments, the water applied was 70% (I0.7), 30% (I0.3) and 0% (I0.0) of full irrigation. It is concluded that broccoli (Brassica oleracea L.cv. Beaumont) gave the highest yield and quality in terms of that water need (I1.0, 361 mm) was fully met. If there is water scarcity in the field where broccoli is cultivated, an economical income from broccoli production can be obtained by saving 30% water or applying water of 253 (I0.7) mm. However, if water stress exceeds more than 30%, the yield and especially the quality of broccoli can be significantly lost.
