Abstract
Jordan suffers from drought and depletion of water resources. In-field crop management, the issue of irrigation scheduling is important and influential. In this research note, a simple method was developed for scheduling surface irrigation of field crops based on inputs of crop ecology, effective root depth, soil texture, soil hydrology, and logical mathematics. It was concluded that the science of mathematics has succeeded to meet academic irrigation scheduling in terms of surface irrigation for field crops based on both soil hydrological and physical traits. Extension scholar has a decision to choose mathematical irrigation model depends on the traditional inputs or updating the model by searching for renewable inputs such as different varieties root depths, optimum row spacing of each crop, drip irrigation mathematical modelling, and digital sensing. In both cases, the input related to the effective root depth is a major and basic factor in mathematical irrigation scheduling. It is, therefore, recommendable that extension research-based systems should focus on basic mathematics to capacitate the complementary role of academics, research, and extension in irrigation modelling, and rural development.
Highlights
Jordan is currently facing climate problems represented by depletion of water resources, high temperatures, drought, salinization of soils, and groundwater sources
This study shows the average gross and net irrigation requirements proposed mathematically for each crop in addition to the average time of days between each irrigation and the other
The prevailing model of irrigation scheduling for field crops in Jordan remains a scientific one, where an extension scholar can depend on his model, other research scholars, and any other sources
Summary
Jordan is currently facing climate problems represented by depletion of water resources, high temperatures, drought, salinization of soils, and groundwater sources. Irrigation scheduling and modelling is a scientific and practical concept of determining the amount of irrigation each time and irrigation intervals (Phocaides, 2007). There is a balance between the two parties (irrigation amount, and irrigation intervals) in Jordan's case due to the conditions of drought, salinity, depletion of water resources, and erratic distribution of rain in the various regions. The availability of modern sewage treatment plants and the availability of high-volume treated water is another reason for the need to schedule irrigation, especially in the production of field and forage crops. Irrigation scheduling can be managed preciously to meet crop water demands, holding the promise of increased yield and quality (Kahlon, 2017). There are major basic inputs that must be discussed in irrigation modelling
