| Abstract | ||
| The Field experiment was conducted at the research station – college of Agriculture – university 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 , protein content of tubers , total yield of crop and the availability of nitrogen and phosphorus in soil after harvesting with the values 71.93 cm , 23.93 % , 890 gm , 17.32 % , 12.93% , 66.37 mega gm ha-1 , 41.00 mg kg-1 soil ,10.98 mg kg-1 soil respectively while the treatment imported biofertilizer + 75% recommended mineral fertilizer + peatmoss carrier gave the beast availability for potassium 186.75 mega gm ha-1, and this treatment of triple interaction was Superior over the control treatments including 100% mineral fertilizer recommendation. | ||
