The Field experiment was conducted at the research stationcollege of Agricultureuniversity of Baghdad / Al Jadria in 2016 -2017 using Randomized complete block design. The experiment consist of 12 treatments with three replicates , field experiment include the following factors , the first factor was biofertilization ) local and imported) , the second factor was the addation of 2 Level of chemical fertilizer (75% and 50%) of the recommended level , while the third factor include using of two type of carriers ( peatmoss or broth media ) , in addation to four control treatments (75% , 50% and 100 %) of recommended chemical fertilizer and control treatment of without bio or chemical fertilizer . Results showed the effect of the triple interaction of biofertilizer + mineral fertilizer + carriers . So the treatment local biofertilizer + 75% recommended mineral fertilizer + peat moss carrier gave the highest value for percentage of dry matter of vegatitive part 42.2% and also the same treatment was superior for plant height , percentage of tuber matter , mean tuber weight , tuber starch content , ‫واخرون‬ ‫راضي‬ ‫محليا‬ ‫المنتج‬ ‫الحيوي‬ ‫السماد‬ ‫تأثير‬35
