The occurrence of shallow saline water tables in arid zones provides for groundwater-fed
natural vegetation and for a substantial amount of irrigated crops' water needs. This is the …

Intercropping is commonly used in the Hetao irrigation district, upper Yellow River basin,
where the main crops are wheat, maize and sunflower. For a better use of land, water …

Many research papers on crop water requirements of vegetables have been produced since
the publication of the FAO56 guidelines in 1998. A review of this literature has shown that …

An irrigation scheduling model (ISM) consisting of a database management system (DBMS),
model base and graphical user interface (GUI) was developed for performing irrigation …

Crop irrigation which results in high water use efficiencies typically uses science-based
irrigation scheduling tools to determine irrigation application timing and quantities. Although …

Site-specific soil hydraulic properties (SHPs) are critical for determining irrigation thresholds
and adopting the best irrigation practices. In this study, we optimized two single-layer SHPs …

The evapotranspiration crop coefficients (K c) that are used to estimate actual
evapotranspiration (ET a) using a two-step approach (ie, K c× reference ET) for limited …

Efficient water management of crops requires accurate irrigation scheduling which, in turn,
requires the accurate measurement of crop water requirement. Irrigation is applied to …

The ever-growing population in the world is expected to reach 9 billion by 2050, and there is
an urgent need to produce more food, feed and fiber to meet these increasing demands …

GlobWat is a freely distributed, global soil water balance model that is used by the Food and
Agriculture Organization (FAO) to assess water use in irrigated agriculture, the main factor …
