Abstract

The aim of this study was to evaluate and select the desirable tuber size and the date of stem cutting on Agria potato variety in semi-cold temperature condition of east Azerbaijan province in Iran. As regard of qualitative factors (Bacterial and fungal infection) there were significant differences between treatments. The experimental results indicated that difference between treatments with evaluation of quantitative factors, a1b2 treatments (Whole tuber, with the stem cut off, 20 days before harvesting) and a1b3 (The whole tuber, with the stem cut off, 10 days before harvesting) were in the class A, but a1b2 treatment in study of quantitative factors, had less fungal and bacterial infection under semi-cold temperature condition of Tabriz and can be introduced to Azerbaijan province and similar areas.

Key words: Agria, stem cut off, yield, bacterial infection, fungal infection.
