Abstract
A study on the influence of nitrogen (N)(100 200 300 and 400 mgN/L) and potassium (K)(100 200 and 400 mgK/L) combinations in solution using the nutrient film technique hydroponic system on the root cation exchange capacity (C.E.C.) of lettuce plant (Lactuca sativa var crispa cv. Poly) was undertaken. Roots were sampled on the 20th 30th and 40th day after germination. Significant increase in roots G.E.C. from 39.47 to 51.11 cmol()/kg due to the N level was only detected on the 40th day of sampling. However increasing of K concentration in nutrient solution at the three sampling times significantly decreased the root C.E.C. values from 29.48-57.00 to 23.25-35.92 cmol()/kg. Root C.E.C. increased from 27.17 to 46.23 cmol()/kg with plant growth stage
