Estimating irrigation water requirements in Europe

Journal of Hydrology, 2009
Summary In Southern Europe, irrigated agriculture is by far the largest consumer of freshwater resources. However, consistent information on irrigation water use in the European Union is still lacking. We applied the crop growth model EPIC to calculate irrigation requirements in the EU and Switzerland, combining available regional statistics on crop ...

Quality of Water Required for Irrigation

2018
Irrigation water can cause damage to irrigated crops and human and animal’s health. Therefore, it is important to monitor the irrigation water regularly. There is a long-term tradition of irrigation water quality (IWQ) monitoring in Slovakia. A number of monitoring stations varied during years from more than 200 to 11 in recent years. The IWQ increased

Planning intraseasonal water requirements in irrigation projects

Agricultural Water Management, 1998
The problem of planning intraseasonal irrigation requirements for the reservoir based projects with an extensive water distribution network is addressed. The network is hierarchical and consists of canals, distributaries or laterals and field turnouts or outlets. Irrigation requirements are estimated by considering the problem at two levels.

Statistical emulators of irrigated crop yields and irrigation water requirements

Agricultural and Forest Meteorology, 2020
Abstract This study provides statistical emulators of global by gridded crop models included in the Inter-Sectoral Impact Model Intercomparison Project Fast Track project to estimate irrigated crop yields and associated irrigation water withdrawals simulated at the grid cell level.

Irrigation Water Requirements for Senegal River Basin

Journal of Irrigation and Drainage Engineering, 1985
The Senegal River is a major natural resource in West Africa where the principal economic resources are agricultural. A proposed irrigation project will provide a significant increase in crop production and will exert a large influence on the economics of Senegal, Mauritania, and Mali.

Quality Requirements for Irrigation with Sewage Water

Journal of Irrigation and Drainage Engineering, 1987
Irrigation is an excellent use for sewage effluent because it is mostly water with nutrients. For small flows, the effluent can be used on special, well‐supervised “sewage farms,” where forage, fiber, or seed crops are grown that can be irrigated with standard primary or secondary effluent.

Irrigation Water Requirements of Green Pea

2015
Peas occupy an important place among vegetable crops in the submountainous region of India. Being a cool weather-loving crop, it occupies a place of prominence among winter vegetables in kandi area, because the kandi area is cooler as compared to other pea-growing regions of Punjab.

Effective Rainfall and Irrigation Water Requirements

Journal of the Irrigation and Drainage Division, 1964
Few studies have been made giving a comprehensive picture of effective rainfall and irrigation water requirements in the United States. The geographical distribution of effective-total rainfall ratios are displayed on two maps for two levels of consumptive use for 22 widely separated stations. This ratio, which varies from less than 50% to greater than

Crop Water Requirement and Irrigation Scheduling

2010
With increasing scarcity and growing competition for water, judicious use of water in agricultural sector will be necessary. This means that exact or correct amount and correct timing of application should be adopted. In addition, it will need more widespread adoption of deficit irrigation, especially in arid and semi-arid regions.
