Abstract

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. Plant height, number of tillers m-2, dry matter production (kg ha-1) and CGR (g m-2 day-1) values were found superior with five irrigations scheduled at CRI, maximum tillering, jointing, flowering and milking stages and among the varieties HI-8759 recorded the maximum values which were on a par with HI-8713. Higher grain and straw yields were recorded under five irrigations schedule. Despite of lower grain yield observed with two irrigations but straw yield was remained statistically on a par with three irrigations. The harvest index (%) was significantly highest with five irrigations and lowest with two irrigations. However, among the varieties HI-8759 recorded significantly higher grain and straw yield. Straw yield was remained at par with HI-8713. Harvest index of HI-8759 was significantly superior over all the varieties. Lowest grain and straw yields were recorded with HI-1544. 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.

Keywords

Irrigation schedules, CRI, maximum tillering, jointing, flowering, milking, varieties and harvest index.

Conclusion

From the results of the present experiment conducted on rabi on wheat, the following broad conclusions can be drawn that the five irrigation schedules at different phenological stages significantly improved growth and yield of wheat. While, significantly lower growth and yield were observed in two irrigation schedules. Among the varieties, the variety HI-8759 registered the highest growth attributes and yield which was on a par with HI-8713 in all the growth parameters and also in straw yield.
