Potato (Solanum tuberosum L.) is one of the most important food crop in terms of global consumption, and it is the second exported crop in Egypt so it a source of hard current. Management of fertilizer nitrogen (N) is a critical component of potato production systems as potato has a relatively high potassium (K) requirement and inefficiently use soil K. A field experiment was conducted at Nubaria district (National Research Centre experimental Station), El-Behera Governorate, Egypt. The main objective of this study was carried out to study the effects of K (80; 60 kg fed-1 that represent 200, 150 kg ha-1) and N fertilizers (40, 50;
60 kg fed-1 that represent 100, 125; 150 kg ha-1) application rate on potato growth, yield, and yield characters.
