Kesan Paras N dan K dalam Larutan Nutrien terhadap Keupayaan Pertukaran Kation Akar Tanaman Selada (Lactuca sativa)

A study on the influence of nitrogen (N) (100, 200, 300 and 400 mgNL-l ) and potassium (K) (100, 200 and 400 mgKL-l) combinations in solution using the nutrient film technique, hydroponic system on the root cation exchange capacity (GE.G) of lettuce plant (Lactuca sativa var crispa cv. Poly) was...
