Abstract
A pot experiment was carried out to study the potassium influence on the growing potato crop on two types from soil (clay loam soil, sandy loam soil) under Sharkia Governorate conditions, during 2004 season. The main results were as follows:
1. Potassium addition tended to increase the dry weight (g pot-1) of potato plant during different growth stages.
2. Values of potassium uptake (mg pot-1) were increased in sandy loam soil more than clay loam soil. The highest values were at harvest and at the fertilizer level K2compared with control treatment.
3. The increasing in potassium fertilizer was lead to increasing the yield, where was due to the cells stimulation and nutrients uptake increase by plants.
