<br/><br/> This work aimed to evaluate the use of Bacillus polymyxa as a biofertilizer for wheat grown on sandy soilDifferent levels of calcium nitrate fertilizer ; 35 , 50 and 70 kg fed - 1 were tested to determined the convenient applied rate at which the bacteria would be more efficient and could enhance yield productivityMoreover , it aimed to assess the role of added iron at a rate of 20 mg kg - 1 soil and molybdenum at a rate of 5 mg kg - 1 soil for wheat and / or the used bacteria
