  • Using infrared canopy temperature and leaf water potential for irrigation scheduling in peppermint (Mentha piperita L.)

    Creator:
    Gallardo, Ivan T.
    Abstract:
    Several methods of infering plant water stress for irrigation scheduling are based upon measurements of the environment in which the plants grow. These measurements include parameters such as soil water content, air temperature, pan evaporation and incident radiation. It is hypothesized that improved estimates of plant water deficit can be...

  • Estimated plant water use and crop coefficients for drip-irrigated hybrid polars

    Creator:
    Gochis, David J.
    Abstract:
    Estimations of plant water use can provide great assistance to growers, irrigators, engineers and water resource planners. This is especially true concerning the introduction of a new crop into irrigated agriculture. Growing hybrid poplar trees for wood chip stock and veneer production under agronomic practices is currently being explored as...

  • Evaluation of evapotranspiration and irrigation performance in Oregon south coast

    Creator:
    Sriprisan, Sirikul (Indi)
    Abstract:
    This study was prompted by the need for improving the efficiency of irrigation systems at the Oregon South coastal areas. Accurate information about evapotranspiration (ET) rates is essential for maximizing the efficiency of irrigation systems. Currently, ET estimates provided by Bureau of Reclamation AgriMet Program are derived from the Kimberly...
