| Title : | EVALUATION ON EFFECTS OF DIFFERENT SALINITY LEVELS IN IRRIGATION WATER FOR CERTAIN COTTON VARIETIES UNDER SOUTHEASTERN ANATOLIA REGION CONDITIONS |
| Abstract : | This study was carried out to determine the effects of different salinity levels in irrigation water for some cotton varieties under Diyarbakır Province of Southeastern Anatolia Region in 2007 using experiments utilizing lysimeter-like drainage type metal containers. Four different salinity levels (T0: 0.32 dS/m, T1: 5 dS/m, T2: 9 dS/m and T3: 13 dS/m) and 3 different cotton cultivars (P1: Berke, P2: Stonville-453 and P3: Teks) were utilized during the treatments. The least affected cultivar from the salinity was Berke. Compared to the cultivar of Berke, the seed-cotton yields of Stonville-453 and Teks were less than 8.3 % and 23.1 %, respectively. The values of salinity threshold for irrigation water according to the cotton cultivars were calculated as Ct=4.45 (Berke), Ct=4.32 (Stonville-453) and Ct=3.72 (Teks). The values of salinity threshold for soil were Ct=6.58 (Berke), Ct=7.46 (Stonville-453), Ct=6.84 (Teks). The results showed there is no significant loss on seed-cotton yield when irrigation water salinity of up to the value of 4.45 dS/m was used. |
