| Abstract | ||
| The study showed the effect of incubation of singal (Azospirillum lipoferum or Bacillus polymyxa) or dual bacteria were isolated and identified from different soils Of south Iraq(Nasarya and Basrah) with different rates nitrogen (0, 150and 300) kgN ha-1 .as urea fertilizer and 50KgP2O5 ha-1applied as superphosphate after soil have been salinized with different levels S3,S6,S9,S12,S24dSm-1 on dry weight and uptake of nitrogen and phosphoure In shoot and root parts of corn( Zea mays L.) plants grown for 60days in sandy loam soil. Results showed negative significant effect on dry weights and uptake of nitrogen and phosphoures of corn plants with increased levels of soil salinity when the single or dual inoculation with bacteria treated with half dose nitrogen (150KgN ha-1)showed positive significant effect on these parameters .The results conducted that dual inoculation bacteria with half dose (150KgN ha-1 ) was highly significant effect than full dose (300Kg ha-1) especially at salinity level 12dS m-1, .Therefore, during soil salinity conditions . The use of single or dual inoculation with bacteria (Azospirillum lipoferum and Bacillus polymyxa) and half dose of nitrogen can give good results for corn crop. | ||
