المستخلص: 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.

المستخلص: Field experiment was conducted during the winter season 2014 - 2015 in one of the agricultural fields in Sarraji area south of Basra province, just 2 km from the center of the province (soil Texture loamy clay), to determine the best combination of distribution of plants among between Rows and hills, to get the best seed yield, Carried out the experiment design (R.C.B.D) with four replication, two factors the first factor four distances between the Rows (30, 40, 50 and 60 cm) and the second factor three spaces between the hills(10, 15 and 20 cm), the factorial experiment is used with 48 experimental units. Results show moral superiority in most of the traits excelled as distance 30 cm between the Rows at all the distances used to achieve the highest seed yield amounted to 3463.94 kg ha - 1 as this distance hasworked to increase the plant significantly increased since given rise the highest rate of highest plants 122.50 cm and also excelled in the 100 - seed weight at a rate 140.20g, while surpassed the distance of 60 cm in leaf area was at a rate of 0.29 m2 and the highest rate of number pods at plant reached 15.48 pod/ plant and the number of seeds pod - 1 average of 4.37 seeds pod - 1 and high Protein content average of 28.51%. As shown by the results moral superiority of 10 cm seed yield3817.85 kg ha - 1 in 93.73 plant height cm and outperformed the distanceof 20 cm in the number of pods plant - 1 13.43 pod plant and the number of seeds/ pod 3.80 seed pod - 1 in 0.22 m2 leaf area and in protein content in seeds 29.36%, while surpassed the distance of 15 cm in 100seed weight was 98.02g The results showed that there is an interaction between the distance of Rows and the hills are significant in most of the traits and the effect of the interaction is similar to the effect of the main factors as excelled combination 30*10 cm in the sum total of seeds yield to 4067.22 kg ha - 1 as well as excelled in plant height was 131.45 cm and also surpassed 100 seed weight with a means 156.64 g, while the combination 60*20 cm in a number pods of 18.8 pod plant - 1 and the number of seeds/ pod of 5.18 seed pod - 1 and leaf area of the plant 0.35 m2 and in Protein content average of 33.11%.
