New crop coefficients estimate water use of vegetables, row crops [PDF]

California Agriculture, 1998
To estimate the water use of vegetable and row crops, crop coefficients were developed using portable Bowen ratio instruments that were constructed and tested against lysimeters.

Determination of Crop Coefficients and Evapotranspiration of Potato in a Semi-Arid Climate Using Canopy State Variables and Satellite-Based NDVI

Remote Sensing, 2023
Estimating crop coefficients and evapotranspiration (ET) accurately is crucial for optimizing irrigation. Remote sensing techniques using green canopy cover, leaf area index (LAI), and normalized difference vegetation index (NDVI) have been applied to ...

Optimization of Irrigation of Wine Grapes with Brackish Water for Managing Soil Salinization

Land, 2023
Water scarcity and quality are critical impediments to sustainable crop production. In this study, HYDRUS-2D was calibrated using field measurements of water contents and salinities in the soil under wine grapes irrigated with river water (Rw, 0.32 dS/m).
