Effects of nanosilver and Nitroxin biofertilizer containing nitrogen stabilizing bacteria on the efficiency of potato seed tuber production from minitubers of Sante cultivar obtained from virus-free tissue cultured plantlets were evaluated in the field. The experiment was a completely randomized block design consisting 7 treatments each in 3 replications including: Normal N similar to the region (T1, control), Normal N+25 mg/L Nanosilver (T2), Normal N+50 mg/L Nanosilver (T3), Normal N+75 mg/L Nanosilver (T4), No N+Nitroxin (T5), 1/2 N+Nitroxin (T6), 1/2 N+Nitroxin+50 mg/L Nanosilver (T7). The results showed that nanosilver had its best effects in a concentration of 50 mg/L (T3) compared to the control. The highest records regarding tuber diameter, number of tubers per each plant, average weight of each tuber and tuber yield were obtained in T7. This combination of Nanosilver and Nitroxin (T7) increased tuber yield 85% and 117% compared to T5 and T1, respectively. According to the results, application of Nitroxin biofertilizer on potato minitubers can reduce the amount of mineral nitrogen fertilizer to half, while producing higher yield.
