AbstractEffect of inoculation with Phosphorus biofertilizer and different dozes of nitrogen and P2O5 on the physiology of growth and development of maize were studied through conducting two different field-experiments at two different locations, Bakrajo ( 35˚ 34˝ 307´N, 765masl) and Kanipanka location (35˚ 22˝ 37´N, 545masl), in sulaimani region. The treatments included, T1(no biofertilizer, only recommended NP) , T2( 50% recommended NP+ Phosphorus biofertilizer), T3( Recommended N+ phosphorus biofertilizer), In addition to vegetative traits (such as plant height, LAI, No. of days to 50% silking, No. of days from 50% silking to physiological maturity(PM)), and reproductive traits (such as 500kernel weight, Biological Yield (BY), Yield, and Harvest Index(HI)), the root-shoot ratio(R/S) was studied in three different stages of growth pre-silking, at- silking and post-silking, results showed increasing in dry weight of root-shoot ratio and significant differences among studied traits, showing positive response of maize hybrid to phosphorus biofertilizer..
