Abstract        

Field experiment was carried out at Research Station of the Faculty of Agriculture, Muthanna University, Iraq, during 2014/2015 season, to study the effect of adding NPK, biofertilizers Bacillus Subtilis and Glomus Mosseae on the growth and yield of maize (Zea may L.). The treatments were i.e control (zero: no vaccine), biofertilizers Bacillus subtilis treatments, Glomus mosseae, both biofertilizers (F0, F1, F2 and F3),  respectively, Three levels of NPK liquid fertilizer i.e. 0, 5000, 7500 mg )C0, C1, and C2 respectively). The experiment design was RCBD with three replications arranged according to split plot. The results showed that the addition of the biofertilizers had a significant effect on the following traits: Plant height of (209.41 cm), and weight of 500 seeds (156.08 g) and yield seeds (6.96 kg/h). NPK fertilizer spraying showed a significant increase, C2 treatment had higher effect more than the other treatments on the following traits: Plant height (210.39 cm), plant nitrogen (22.20%), plant phosphorus (4.24%), plant potassium (17.99%), weight of 500 seeds (157.06 g), biological yield (373.39 kg/ha) and yield of seeds (6.91 kg).
