What is irrigation?
– Irrigation refers to purposely providing land with water, other than rain, for improving productivity
– Irrigation usually implies the existence of infrastructure and equipment for applying water to crops, such as irrigation canals, pumps, sprinklers or localized watering systems.
– It t also includes manual watering of plants using buckets, watering cans or other devices.
– Uncontrolled land flooding by overflowing of rivers or streams is not considered irrigation.
– Irrigation includes any process under which water is moved from a water source to apply to an agricultural crop.

Method of Irrigation
– Surface irrigation refers to a system for partially or completely covering land with water for the purpose of irrigation. There are various types including furrow, border-strip and basin irrigation. Basin irrigation includes submersion irrigation for rice.
– Sprinkler irrigation refers to pipe networks through which water moves under pressure before being delivered to the crop via sprinkler nozzles. The system basically simulates rainfall in that water is applied through overhead spraying. Sprinkler irrigation systems are sometimes known as overhead irrigation systems.
– Localized irrigation is a system where the water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant. There are several types: drip irrigation (where drip emitters apply water slowly to the soil surface), spray or micro-sprinkler irrigation (where water is sprayed to the soil near individual plants or trees), and bubbler irrigation (where a small stream is applied to flood small basins or the soil adjacent to individual trees). Other terms commonly used to refer to localized irrigation are micro-irrigation, trickle irrigation, daily flow irrigation, drop-irrigation, sip irrigation, and diurnal irrigation.

OTHER TYPES OFOTHER TYPES OF WATER MANAGEMENT PRACTICES WATER MANAGEMENT PRACTICES
Wetland and inland valley bottoms are lowland areas subject to seasonal flooding, that are used for cropping when covered with water. Water control structures, such as canals, may be constructed to help in the crop cultivation.
Flood recession cultivation refers to areas along the edge of rivers or other water bodies where cultivation occurs, making use of water from receding floods
Spate irrigation is a method of random irrigation using the floodwaters of a normally dry water course or riverbed (wadi). Spate irrigation is also referred to as floodwater harvesting
