EFFECT OF SALINITY OF IRRIGATION WATER AND SPRAYING AMINO ACIDS ( PROLINE , ARGININE ) IN THE GROWTH AND HOLDS POTATO Solanum. tuberosum L.

Abstract

The experiment in the field of Scholastic my family in the province of Diyala- Mandali hand for the Fall 2012 season and which planted the potato Solanumtuberosum L. Cv. Riviera class Elite has been aimed experiment to see the effectof the type of irrigation water used and the amino acids added by spraying andinteraction in recipes vegetative growth and winning the potato. Experience hasincluded the effect of three levels of irrigation water salinity (1.6, 3.2 and 4.3)dS.m-1 and has a drip irrigation in a way, and added amino acid Proline,Arginine, and in three levels of 0, 200 and 250 p.p.m. The experiment carriedout according to the design of a skateboard dissident Split Plot as representedsalinity levels of irrigation water under the President the amino acids in themain concentrations below under three replicates has been tested differencesbetween the averages by test LSD at the 5% level of probability. The results canbe summarized as follows:1.Increased salinity of irrigation water from 1.6 to 4.3 dS.m-1 to reduce plantheight and total chlorophyll and quotient total and quotient the marketable.2.Marked by spray treatment Proline a concentration of 200 p.p.m and interferewith irrigation water salinity 1.6 dS.m-1 to give the plant's highest and thehighest total chlorophyll concentration and largest quotient holistic and holds amarketable compared to other interactions.
