CARROT (Daucus carota L.): YIELD AND QUALITY UNDER SALINE CONDITIONS

33791

The effects of 6 irrigation salinity levels on yield and quality, vegetative growth, water consumption and ion accumulation of carrot (Daucus carota L.) were studied under greenhouse condition in Tokat/Turkey. The experiment was conducted as a randomized block design with 5 replications using a total of 30 pots. The synthetic saline waters were prepared by adding CaCl2, MgSO4 and NaCl salts to tap water. Tap water (ECi= 0.75 dS.m^-1) was applied as a control treatment. Irrigation water salinity (T0= 0.75, T1= 1.5, T2= 2.5, T3= 3.5, T4= 5.0 and T5= 7.0 dS m^-1 ) led to increase in soil salinity, carrot flavor, leaf Cl and Na content and decrease in fruit yield, fruit diameter, water use efficiency and leaf K content. Increasing irrigation water salinities did not significantly affect unit weight, color index, height and penetration resistance of fruit, water consumption, leaf Ca and Mg contents but fruit quality such as flavor and dry matter content improved due to salinity, however 50% yield loss occurred even below at 2.5 dS m^-1 soil salinity level.
