AbstractThe experiment was conducted in a field of Anbar governorate /Fallujah city 60 km western of Baghdad at near Euphrates river bank were planted at 20th of January during for 2013 and2014 Potato tubers Solanum tuberosum L. cultivar barren class Elite, the Randomized Complete Block Design (RCBD)was used and L.S.D. test at level 5%. The chemical fertilizer treatment T14 (400.120.240) NPK increase N and K in leaves and NO3 in tubers for both season significantly to 1.93% ,1.76%, 47.66 mg.kg-1 and 1.89% , 1.75% ,47.66 mg.kg-1 respectively and the content of N and protein in tubers for both seasons to 2.37% , 0.31% and 0.32% , 2.44% on respectively. The influence of Cytokinin treatment CPPU 10 ,5 mg.L-1 on qualitative properties of yield were given the highest dry matter%, starch%, specific gravity g.cm-3and TSS% at first season which were 20.95%,14.67% , 1.083 g.cm-3 , 6.86% respectively, and were given the highest dry matter ,starch 19.69% and 6.25% respectively. The control treatment increase the content of NO3 in tubers to 28.33, 27.66 mg.kg-1 for both season respectively.
