Abstract
Field experiment was conducted in Hibhib in Diyala province during the growing season in 2015 to study the six treatments of foliar arginine acid and yeast. Treatments were arginine acid concentration at 200 mg l-1, arginine 300 mg l-1, yeast 5 g l-1, a mixture of 200 mg l-1 arginine, yeast solution 5 g l-1 (1:1 ratio), a mixture of arginine 300 mg l- 1 + 5 g l-1 yeast solution by 1:1 ratio and control on three genotypes of potatoes which were Emma, Rivira and Loane. The experiment was carried out using split plot in RCBD, where genotypes treatments in the secondary plot with three replicates, differences between the averages was tested according to Duncan at 0.05 probability. the Study proved superiority of installation plants Loena sprayed with a mixture of yeast and arginine acid concentration of 300 mg ltr-1 which gave best plant height 66.66 cm, while installation plants recorded Emma sprayed with yeast highest number of stolen 6.00 stem plant2, as well as excelled installation plants Emma sprayed with a mixture of yeast arginine acid 300 mg ltr-1 highest number of leaves 112.00, while genotype Rivira plants sprayed arginine concentration of 200 mg l-1 recorded highest leaf area 1920.3 ds2 . Loena sprayed with a mixture of yeast histidine and arginine 300 mg l-1 gave highest content of chlorophyll in leaf which was 51.70 Spade.
