Two field experiments were conducted at El Rayyan region, Fayoum Governorate, Egypt, during the two successive winter seasons of 2010\2011and 2011\2012 to study the effect of application of potassium fertilizer levels (0, 50 and 75 kg K O\faddan, one faddan = 0.42 2 ha) under skipping one irrigation (3 or 4 rd th irrigation) on growth and yield of chickpea (Cicer arietinum L.) cv. Giza 3. The main findings of this study showed that skipping one irrigation or increasing potassium fertilizer levels led to significant reduction in all characters under study in both seasons (plant height, total dry weight \plant, number of branches\plant, number of capsules\plant, dry weight of capsules\plant and dry weight of leaves\plant at 115 days after sowing. Skipping the 3rd or 4th irrigation led to declined in weight of capsules\plant, seed yield\plant, shelling%, seed index, seed, straw and biological yields \faddan. Meanwhile, application of potassium induced stimulating effect on yield and its components under the present study and the rate of 75 Kg K2O\faddan increased all characters under this study i.e. weight of capsules\plant, seed yield\plant, shelling % seed index, seed, straw and biological yields. It is clear from the results that skipping the 3rd or 4th irrigation led to reduction in protein and carbohydrate percentages compared with the control, while there was a significant increase in protein and carbohydrate percentages of chickpea seed due to application of potassium fertilization. The interaction between skipping irrigation and potassium fertilizer levels was significant in all characters under study and the best treatment was 75kg K2O \faddan with normal irrigation.
