Abstract:
Field experiment was conducted during the fall season of year 2014 done in farmer's fields in the Auffia area southwest of Missan province (about 14 km .1 - m the soil was clay loam with 4.2 ds . city center)fromThe objectives were to determent the response of Sunflower (Helianthus annuus .L) hybrid Flame to amino acid - Proline in order to reduce water stress. The experiment executed in split - plot (R.C.B.D) design with three replicates. The experiment were three levels of proline (P1 spray Proline concentration in addition to the control 1 - ; P2 spray Proline concentration 100 mg L 1 - 50 mg LP0 as distilled water were located in sub - plot) while the other factor was irrigation period (W1= irrigation every 10 days; W2= irrigation every 15 days andW3= irrigation every 20 days) as the main - plot.The crop sprayed with Proline acid after mixed with water in two phases of growth is V6 (the phase of six real leaves) and R1 (flowering stage) with application of irrigation system. After the plants reaches to physiologic maturity and growth characteristics measured; the contains of yield and quality characteristics and the results were analyses statistically and compared with averages LSD test. The results showed the following.e uhigher valgave to the control compared 1 - 100 mg Lwith praying ProlineS - 1for growth measurement in mean of plant height; number of leaves; stalk diameter ; head diameter and LAI and they were (126. 19 cm ; 28. 60 leave ; 23. 27 mm; 17. 48 cm and 2. 28) respectively. Also increased the mean of yield and seed yield; weight of 100 seed the; 1 - head er of seedsnumb components) 1 - 16 ton h .and 1 1 - 48 tons h .0 4 g; 3 .40 seeds; 6 .(1003 oil yield ofrespectively.2 - Applying irrigation every 10 days improve all growth characteristics; yield's components and quality compared to applying irrigation every 20 days, which gave the lowest mean in above characters.3 - The results also showed that the interaction of applying Proline and irrigation periods was significant for the most of the growth characteristics; yield and quality characteristics. It was concluded from to reduced period of irrigation not differ from hich W .1 - 100 mg L Proline once applying daysevery 15 applying irrigation every 10 days for most of the studied characteristics. Is the most important yield; oil production and this can saves 25% of irrigation water under conditions - Missan Auffia area. That reduces the wastae of water resources or expansion of the agricultural area and increase the yield.
