Abstract
The experiment was conducted in the field of Scholastic in the province of Diyala-Mandali hand in the fall season 2014, which planted the potato Solanum tuberosum L. Cv. Riviera class Elite. The aim of this experiment to know the effect of the salinity levels of irrigation water, amino acids , the method of addition and interaction in recipes vegetative growth and winning the potato. Experiment included three levels of irrigation water salinity (2, 3.6 and 5.1) ds m-1 and in drip irrigation in method, and added Amino acid Proline and Arginine with two levels 0 and 200 ppm which sprayed in two ways foliar application and with water irrigation. The experiment carried out according to Split Plot design. Water salinity levels represented main plots and amino acids represented sub plots with three replicates, the results were tested under LSD at the 5% level of probability. The results can be summarized as follows:- 1- Increased salinity of irrigation water from 2 to 5.1 ds m-1 reduced plant height, total chlorophyll, total yield and the marketable yield. 2- Treatment OF Proline at 200 ppm and interfere with irrigation water salinity 2 ds m-1 increased the plant's height, total chlorophyll in leaves and total yield and a marketable yield compared to other treatments.
