THE USE OF AZOTOBACTER AND AZOSPIRILLUM AS A CATALYST FOR COEXISTENCE OF ZUCCHINI SQUASH WITH SALINITY

Chroococcum and A. brasilense bacteria were isolated identified from the root surrounding area of Arundo donax andCladium marisas plants growing in different areas Ramadi city order to be used pollinating seeds zucchini squash plant. A pot experiment was carried out spring season on 16 ⁄ 3 2019 one fields College Agriculture - University Anbar, by following design complete randomized sectors RCBD. It included two factors salinity irrigation water four levels S0, S1, S2 S3 (1.3, 3, 5 7 dSm-1) factor adding bacterial isolates Azotobacter L1 Azospirillum L2 their mixtures L3, without L0 inoculum study effect pollination some growth characteristics irrigated with levels. The results showed a decrease plant height, number leaves dry weight shoots 53.48 cm, 33.00 leaf-1, 25.97 gm-1 at S0 level, 26.95 14.08 g-leaf-1, 12.41 g-leaf-1 level. treatment mixture L3 achieved significant increase weight, it 55.53 44.00 leaf-1 28.33 compared comparison caused an nitrogen concentration vegetative parts 1.77% 2.07%, phosphorus potassium 0.63 2.37% 0.21 0.56%. nitrogen, significantly increased when inoculation treatments obtained, recorded highest values reached 2.75% N level gave value for potassium, which 0.75 2.87%, respectively,
