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...

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...

Creator:: Carrijo, Osmar Alves
Abstract:: The major objectives of this study were an evaluation of the Meteorological Office Rainfall and Evaporation Calculation System (MORECS) evapotranspiration (ET) model using the Penman-Monteith equation and comparison of the MORECS and measured surface resistance. Meteorological, soil and plant parameters were measured in an alfalfa field over two growing seasons....

Creator:: Araki, Yoshitaka
Abstract:: Evaluation and sensitivity analysis of a soil-water--- atmosphere-plant simulation model, SWATRE, developed by Feddes et al (1978) in The Netherlands was conducted. The evaluation was performed with the observed data obtained by Cuenca (1978) for three different irrigation levels in UC82 variety tomato fields in Davis, California. SWATHE requires about...
