Abstract

Pots experiment was conducted in green-house belong to green garden of Biology Department, College of Education for pure science Ibn-AL- Haitham Baghdad University, during the growing season 2011, the experiment included studying the effect of four concentrations of potassium sulphate (0,200,400,600) mg.L-¹ as a source of potassium and three concentrations (0,75,150)mg.L-¹ of Cytokinin and their interaction on some growth parameters (Dry weight, Relative growth percentage%, the concentration of Nitrogen, Phosphorus, Potassium, Calcium and Magnesium for Lentil plant (cv. AL Baraka). The experiment was designed as Completely Randomized Design by three replicates (4x3).Result indicated a significant effect for potassium and Cytokinin on the studied growth parameters and there was a significant effect for the interaction particularly in the case of the concentration 400mg.L-¹ Potassium and 150mg.L-¹ Cytokinin that gave the best values for all growth parameters studied.
