Abstract

A field experiment during spring and fall seasons of 2015 was carried out, the spring season experiment was conducted in general commission of agricultural researches (Abu-Ghariab) while the fall season experiment in Field crops department research station- University of Anbar (Abu-Ghariab region) that located on latitude 33.22 ˚ N and longitude 44.24 ˚ E and altitude 34.1 meter from sea level in silt loam soil. The experiment included the study of seed Soaking by four concentration of pyridoxine 0, 2, 4, 6 P g L-1 with foliar application with four concentration of Boron 0, 75, 150, 225 mgB L-1 in form of H3BO3 (17% B) in order to study SOD content and some of growth and yield traits for sun flower (Helianthus annuua L. cv. Luleo). The experiment was conducted in arrangement of Split plot in RCBD with three replications, where the Boron concentration occupied the main plot while the Pyridoxine concentrations occupied sub plots. The results summarized as following:
The seed priming with 4 Pe g L-1 led to give highest activity of SOD enzyme at the beginning of flowering, highest average of leaf area, B concentration in leaves, weight of 100 seed, yield in area 4.46, 3.32 ton ha-1, oil content 52.00, 47.00% in the two seasons respectively, while the concentration 6 P L-1 recorded highest activity of SOD after 30 days from planting date. The foliar application Of 150 mg B L-1 significantly affected in giving highest average of leaf area, boron concentration in leaves in the first seasons, while the concentration 225 mg B L-1 gave highest activity of SOD at the beginning of flowering, number of seed in disc, weight of 100 seed 7.60 and 7.31 gm and seed yield 4.33 and 3.44 ton ha-1 for both seasons, as well as it gave highest average of leaf area and boron concentration in leaves for the second season only. The interaction between P and B concentrations significantly affected in most traits under study, the treatment of 4 g Pe L-1 X 150 mg B L-1 and 225 g B L-1 gave highest average of seed yield for both seasons 4.86 and 3.95 ton ha-1 respectively.
