A field experiment was carried out in silty loam soil in General commission of agricultural researches station in spring season and in Field crops department research station- University of Anbar (Abu-Ghariab) in the fall season of 2015 that located on latitude 33.22 ˚ N, longitude 44.24 ˚ E and altitude 34.1 meter from sea level, in order to study seed priming with salicylic acid 0, 150, 300, 450 mg SA L-1, with four concentration of foliar application with Zinc 0, 50, 100, 150 mg Zn L-1) on form of ZnSo4.H2O (Zn 35%) in enhancing SOD activity and some of growth and yield of sunflower crop (cv. Luleo). The experiment was carried out in arrangement of Split plots in RCBD with three replications. The results of the experiment were summarized as following:
The seed priming with 150 mg SA L-1 has led to give highest activity of SOD after 30 days after sowing date, weight of 100 seed and seed yield 4.65 ton ha-1, while the concentration 300 mg SA L-1 led to give highest activity of SOD at the beginning of flowering stage and Zn concentration in leaves in both seasons as well as the same concentration has led to highest average of leaf area, number of seeds in disc, weight of 100 seed 6.91 gm and seed yield 3.91 ton ha-1 in second season. The foliar application with Zn led to significant increase in most studied traits, the concentration 100 mg Zn L-1 gave highest activity of SOD at the beginning of flowering stage, highest average of number of seeds in disc, weight of 100 seed and seed yield 4.56 and 3.92 ton ha-1 in both seasons respectively. The same concentration recorded highest average of oil content in seeds 48.31% in second season, while concentration of 150 mg Zn L-1 gave highest average of this trait in the first season 51.78%. The two interaction between SA and Zn significantly affected in most studied traits, therefore the treatment of 150 mg SA L-1 with 100 mg Zn L-1 gave highest average seed yield in the first season of 5.04 ton ha-1.

A field experiment was carried out in the soil of alluvial tissues fusion in summer season of 2013 in Abu Flees area which is a part of Al Khalidiya district which lies on longitude 43Oand latitude 33O to investigate the effect of four levels of potassium (0,40,80&120 kgK.ha-1 ) and four concentrations of Zinc ( 0,30,60&90 mgZn.L-1), which were added as a leave nutrition, in the growth and yield of Soybean crop of GS lll class. In experiment used the order of the split-plot according to the randomized complete block design (RCBD) and four replications. Potassium levels occupied the main split-plots, while Zinc concentrations occupied the secondary split-plots. The results of the experiment are summarized as follows:
The 90mgZn.L-1 concentration revealed the highest average of plant height, the rate of Zinc and Potassium in the leaves, and the seeds crop product. This concentration did not differ significantly in most of its traits with the concentration 60 mgZn.L-1 which was prominent and high significantly in the leave area, dry plant weight, root length. The level 120 kgK.ha-1 indicated the highest average in the plant height, leave area, the weight of dray plant, the roots length, the rate of Zinc and Potassium in the leaves, and the product of plant seeds. This was not significantly different in most traits under study with the level 80 kgK.ha-1. The interaction between Potassium and Zinc significantly affects all the studied traits. The interaction between the level of 120 kgK.ha-1 and the 90mgZn.L-1 concentration revealed the highest rate in leaves area (249.8 dcm2), the length of the main root (34.65cm), seeds crop ( Finally, it is concluded that there is a significant response in the studied traits when adding Potassium to the soil and at the nutrition of leaves with Zinc.

Afield experiment had been carried out in autumn -2006 to study the effect of irrigation depth and foliar nutrition application of Zinc on some growth for the spicies Zea mays L.var IPA 5012. A factorial experiment was applied according to Randomized Complete Block Design with three replicates .The experiment included two treatments namely; irrigation (I) with two levels (I1 and I2). The I1 treatment received enough irrigation in germination and maturing stags which equal (130 and 150) mm respectively, but received deficient irrigation in vegetation and flowering stags which equal (180 and 140) mm respectively. The I2 treatment received deficient irrigation in germination and maturing stags which equal (65 and 95) mm respectively, but received enough irrigation in vegetation and flowering stags which equal (225 and 215) mm rspectively. The second treatment namely Zinc spraying (Zn) which contents three levels (Zn0, Zn1 and Zn2). The Zn0 treatment, is the control (sprayed with water only). The Zn1 treatment in which the plant sprayed three times with 50 mg Zn/ L, and the Zn2 in which plant sprayed three times with 100 mg Zinc/ L.
The results showed: that I2 treatment gave the highest growth indicators particularly net weight seed/ ear, weight of one seed and wet weight of plant which shows (15.6, 4 and 12)% increament continuously comparing with I1 treatment. While The Zn1 treatment gave the highest level for net weight seed/ ear, wet weight of plant ,number of seeds in one line and leaf width. The increasing percent were (6.7, 2.3), (16.9, 10.8), (6.7, 1.5), (5.9, 5.0)% in comparesing with Zn0 and Zn2 treatments, continuously. Also Zn2 treatment showed a significant increament in ear length. The increasing percent was 6.8% in comparing with Zn0. I2Zn1 achieved a significant increament in the average of net weight seeds/ ear, and weight of one seed. Also interaction of Zn1 with I1 and I2 showed a significant increament in the average of seeds number in one line and leaf width.

ANBAR JOURNAL OF AGRICULTURAL SCIENCES, 2008, Volume 6, Issue 2, Pages 198-210

This research was carried out using three local cultivars of pomegranate (Salemi, Rawa seedless and Gelawi) for the growing seasons (2000–2001). Two studies were performed, the first study dealed with the flowering habits on the fruiting units, intension, the percentage of perfect and male flowers during flowering period, while the second study dealed with the effect of flowers thinning during the last cycle of flowering which take place during the period from 20 may to 30 june and foliar sprays of Zn at a concentration of 1 & 2% which carried out on (1/ 7/ 2000 and 1/ 10/ 2000) the objective of this studies was to increase the percentage of perfect flowers in the following season and its effect on the yield . The experimental results shows the following:
1. The male flowers were exist before the perfect flowers by 10 days and then both types of flowers were increased at interected cycles to reach the highest intension during the period (10 April to 30 June). The percentage of perfect flowers was 86.25 % at the first cycle of flowering while the second cycle formed the remaining percentage which is 13.75% and the number of male flowers were higher than the perfect flowers at a ratio of (2.10–2.81).
2. There are a significant differences in number of total flowers, perfect flowers and male flowers between cultivars. Rawa seedless cultivars was the highest in number of total flowers while the Gelawi cultivar was the highest in the percentage of perfect flowers. In spit of the deffernces in the percentage of formed flowers on fruiting units from cultivar to another, they are all appered on small shoot (spur) with one or two years old and they reached the percentage of (23.73, 37.74, 38.52%) for the three cultivars on the new shoots, shoot 1-2 years old respectively.
3. The results showed that flowers thining of hast cycle of flowering, causes a significant increases on the percentage of perfect flowers and on the percentage of fruits set in the following season (2001) at a ratios of (6.89%, 5.34%) for both characters respectively, while the increament was (3.23% and 3.40%) when Zn at 2% and the effect was increased when there is an interaction between thining and appling Zn.
4. Thining and folair sprays of Zn causes a reduction in fruit weight at a ratio of (2.1% and 1.3) respectively, while this reduction was not in parrall with the increament in the percentage of perfect flowers and the percentage of fruits set. which causes an increases in total yield up to a percentage of 10.76% when thining was done, 2.37% when Zn was sprayed and the increament reached 16.40% with the interaction between them.

In the first experiment Zinc was applied to the soil, Zinc levels were 4.0 and 8.0 kg Zn.ha-1 and control treatment (without Zinc). The Zinc was added from two sources, inorganic (ZnSO4.7H2O) and organic (Zn-DTPA). In the second experiment Zinc was applied as a foliar application. Zinc levels were 0.4 and 0.8 kg Zn.ha-1 and control treatment (spraying with water only). The results showed that number of spike / m2, weight of 1000 seed and number of seed / spike increased significantly when Zinc were added at 8.0 kg Zn ha-1 as a soil addition and 0.8 kg Zn ha-1 as a foliar addition compared to control treatment. The rate of increases by soil application of 8.0 kg Zn ha-1 of spike / m2, weight of 1000 seed and number of seed / spike were 21.8 and 28.8, 6.6 and 7.4, 22.0 and 10.6 for two wheat cultivars, bread wheat cv. Abu-Ghraib 3 and durum wheat cv. Doar 85 respectively. Also, the same components increased significantly by foliar application of 0.8 kg Zn ha-1. The rates of increasing were 13.4 and 15.7, 13.4 and 15.7, 17.6 and 13.7 for two wheat cultivars, bread wheat cv. Abu-Ghraib 3 and durum wheat cv. Doar 85 respectively. In general, soil addition of zinc resulted in higher increases in yield components compared to foliar addition of zinc.
