The field experiment was conducted during the rabi season of 2021-2022 at the Regional Agricultural Research Station, Chintapalle, Visakhaptnam, ANGRAU, Andhra Pradesh to study the effect of different irrigation schedules and varieties on growth and yield of wheat under high altitude and tribal area zone conditions of Andhra Pradesh. The experiment was laid out in split-plot design with the three irrigation schedules i.e., irrigation at CRI, maximum tillering, jointing, flowering and milking stages (M1), irrigation at CRI, flowering and milking stages (M2) and irrigation at CRI and milking stages (M3) as main plots and four varieties i.e., DBW-252(V1), HI-1544 (V2), HI-8759 (V3) and HI-8713 (V4) as subplots. Number of days taken to 50% flowering was found significantly less (71.5 days) with five irrigations scheduled at CRI, maximum tillering, jointing, flowering and milking stages followed by three (82 days) and two (82.6 days) irrigation schedules and among the varieties there was no significant difference was observed. The highest Gross returns (91,072/-), Net returns (52,022/-) and B:C ratio (2.33) was found with five irrigations and among the varieties HI-8759 achieved highest Gross returns (86,494/-), Net returns (49,444/-) and B:C ratio (2.32). The challenges of the study is to find out the best variety among the tested for a suitable irrigation schedule and for the first time durum wheat varieties were tested in High Altitude and Tribal Area zone conditions of Andhra Pradesh
