Abstract

This study was conducted in order to determine the effect of vermicompost (V) on macro and micro nutrients of lettuce ( Lactuca sativa Var. crispa) exposed to salt stress (SS). V doses; 0 (V0), 2.5% (V1) and 5% (V2) (w/w) and salt stress levels; control (SS0) (0 dS m(-1) NaCl), medium salt stress (SS4) (4 dS m(-1) NaCl), severe salt stress (SS8) (8 dS m(-1) NaCl) were used. In order to make evaluation in terms of the nutrients, plants were kept under controlled conditions (relative humidity 50-55%, daytime/night time temperature 24/20 degrees C) in the greenhouse for 46 days (May 24 and July 10, 2017). While the medium and severe salt stress decreased the P, K, Mg, Fe, Mn and Zn concentrations of plants significantly, compared to the control, it caused increase in N and Na concentration. While Na decreased due to the V, other mineral element concentrations increased significantly and these increases were found more effective in 5% V application. The effect of SS x V interaction was statistically significant in terms of N, P, Mg, Na, Fe, Mn and Zn, whereas it was found insignificant for K, Ca and Cu. It was shown that in lettuce growing, V applications in areas with salinity problems could contribute to reducing the toxic effects of salinity on the plant and improving the imbalance in nutrient intake.
