Crop Water Requirements and Irrigation Guidelines Quiz

FAO Irrigation and Drainage Paper No. 56

• Discusses guidelines on the safe re-use of wastewater for irrigation purposes

Irrigation Design Criteria

• Proposed methodologies/strategies for development of location-specific irrigation design criteria by some authors

Soil and Water Terminology

• Information on soil and water terminology can be found in a specific document

Unlined Canal

• An unlined canal is a type of canal without a liner or coating

Water Balance

• Refers to the balance between water input and output in a system

Unconfined Aquifer

• The upper surface of the zone of saturation is served by the water table

Rainfall Pattern

• The type of rainfall pattern characterized by five wet months with more than 200 mm/month precipitation is known as a humid climate

Government Privilege

• The government grants a license or permit to use water resources

Well Log

• Provides information about the geological formation and water-bearing properties of a well

Reservoir Storage

• The active storage volume of water in a reservoir is the amount of water that can be used for irrigation

Crop Coefficient Ratio

• Measures the evapotranspiration rate of a crop relative to a reference crop

Crop Evapotranspiration Rate

• Is affected by factors such as climate, soil, and crop type

Application Efficiency Ratio

• Refers to the ratio of water actually used by the crop to the water applied through irrigation

Crop Water Requirements

• The primary component is the evapotranspiration rate of the crop

Effective Rainfall

• Directly contributes to the crop water requirements by reducing the need for irrigation

Leaching in Agriculture

• Refers to the process of dissolving and washing away nutrients and salts from the soil

Drop in-line Canal Structures

• Designed to reduce the energy of flowing water and prevent erosion in a canal

Effluent Discharges

• Involve passing wastewater into a body of water or land
