Two separate experiments were carried out in a private farm in El-Matria; Dakahlia Governorate, Egypt during two successive seasons 2009/2010 and 2010/2011 to study the effect of potassium sources (potassium mono phosphate 52% K2O potassium sulphate 50% K2O and potassium citrate 38% k), levels (0, 60 and 120 kg K2O/ fed for each source), phosphorus sources (calcium super phosphate 15.5 % P2O5, rock phosphate 30 % P2O5 and phosphoric acid 85 %P2O5) and levels (0, 30 and 60 kg P2O5/fed for each source) on vegetative growth, tuber yield and chemical constituents of potato (Solanum tuberosum L.) "Spunta". Treatments were arranged in randomized complete block design in three replicates. The obtained results indicated that both potassium mono phosphate at 120 kg K2O/fed and phosphoric acid at 60 kg P2O5/fed gave the highest values of vegetative growth parameters, tuber yield and its quality in both seasons as compared with other treatments and the differences were significant.
