Shoot water content and reference evapotranspiration for determination of crop evapotranspiration

African Crop Science Journal, 2017
Determination of water requirement for crops in resource limited areas is  challenging, yet worsened by the common assumption that all crop varieties within a species have similar water requirements. The objective of the study was to  indirectly determine crop evapotranspiration of soybean varieties, using reference evapotranspiration and shoot water ...

Turning Water to Wine: An Analysis of Texas Wine Industry Water Management

Irrigation and Drainage, EarlyView.
ABSTRACT The Texas wine industry is expanding in scale and reputation during a period when sustainability concerns are increasingly visible and valuable to grape growers and wine producers in Texas. Most vineyard hectarage in Texas is in the High Plains and Hill Country American Viticultural Areas (AVAs), which rely on regional aquifers for water. With

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Studies on Evapotranspiration from Crops

Journal of Agricultural Meteorology, 1987
The problems are whether evapotranspiration (ET) from paddy field would be affected by growth stage and by rice varieties, and whether the radiation method and Priestley-Taylor method for estimating ET would be applicable to paddy field.ET was measured with microlysimeter (Tomar and O'Toole, 1980A) at the eight test plots (N1-N8) in which cultivar ...
