The growth and yield of cotton (Gossypium hirsutum L.) in the semiarid Texas Rolling Plains is driven by the amount of water available to the crop through rainfall and irrigation. Various methods have been developed for scheduling the irrigation of agricultural crops. A project is being conducted in the Texas Rolling Plains for demonstrating various irrigations scheduling methods to producers in this region. These include irrigation scheduling using tensiometers, soil moisture sensors, smartfield sensors, and crop evapotranspiration data. By matching the water application according to crop water requirements, it is possible to significantly improve on-farm irrigation efficiency. In this presentation, we are presenting the preliminary results from this study.
