Abstract

This study was conducted during growth season in privet farm (10)km from south east of Falluja beside Euphraties river bank in loamy –caly soil , to study the effect of three levels of potassium fertilizer (10, 60 and 120) Kg K2O / dm and two direction of row ( direction paralele to the sun light from the east to the west and on vertical direction to the sun light ) on the growth and yield of potato CV. Desiree using split – plot design the experiment results showed a significant increase in plant height and total yield of 51.09 cm and 8.63 ton / dm . Potassium at the rate of 120Kg K2O / dm with dire row direction paralele to sun light significantly increased tubers hydrogen and phosphorus content up to 2.397% and 1.145 % respectively , while using K2O at rate of 120Kg K2O /dm and row vertical direction to the sun light significantly increased tubers potassium content up to 5.79 % .
