Field experiment was conducted during the fall season of 2014-2015 year in Auffia district southwest of Missan provenance. In order to study the response of sunflower (Helianthus annuus.L) var- flame to Proline amino acid and could elevate shortage of water. The experiment design was R.C.B.D with three replicate, where the treatments arrangement were in split plot design; the whole plots were irrigation intervals (W1=every 10 day; W2=every 15 day and W3=every 20 day), while the subplots were Proline treatment (P0=without spray; P1=50 mg L-1 and P2=100mg L-1). The outcome of results were analysis and the means were separated using L.S.D. The results showed that the interaction between Proline concentration treatment and irrigation treatment were significant in such that when applying 100 mg L1 (P2) and (W2) which applying irrigation every 15 days did not sign significantly from control irrigation which is every(10) days irrigation . This finding would save approximately 44% from irrigation water under the current environmental condition of Auffia-Missan. Also the result showed that the spray Proline 100mg L-1 gave higher number of leave ,head diameter and LAI ;28.6 , 17.48 and 2.28 respectively .Also the same treatment (100mg L -1 Proline) gave the highest seed number per head , 100 seeds weight and grain yield (1003.40 seed , 6.04 g and 3.48 ton h-1) respectively . The result showed applying irrigation every 10 days gave the highest result in all traits under the study.
