How is good water management beneficial for farming?

Farmers apply water to crops to stabilize and raise yields and to increase the number of crops grown per year. Globally, irrigated yields are two to three times greater than rainfed yields. Thus, a reliable and flexible supply of water is vital for high value, high-input cropping systems.

What are the irrigation techniques?

The three main methods of irrigation are surface, sprinkler, and drip or microirrigation. In surface irrigation, water flows over the soil by gravity. Sprinkler irrigation applies water to soil by sprinkling or spraying water droplets from fixed or moving systems.

Which is the heart of irrigation system?

Head Irrigation Unit: This consists of water pumps, water filtration systems this is the heart of the system.

What is adequate irrigation?


What are the components of sprinkler irrigation system?

A sprinkler system usually consists of the following components (i) A pump unit (ii) Tubings- main/submains and laterals (iii) Couplers (iv) Sprinker head (v) Other accessories such as valves, bends, plugs and risers. (i) Pumping Unit: Sprinkler irrigation systems distribute water by spraying it over the fields.

Where is drip irrigation used?

Drip irrigation is most suitable for row crops (vegetables, soft fruit), tree and vine crops where one or more emitters can be provided for each plant. Generally only high value crops are considered because of the high capital costs of installing a drip system.

How do you unblock a drip irrigation system?

Acid Treatment Sulfuric acid, phosphoric acid, nitric acid and hydrocholoric acid are some of the chemicals that can be used to unblock or unclog drip irrigation systems or drip tapes. These chemicals can be passed into the drip tapes with fertigation equipments like the venture injector or dosing pump.

How successful is drip irrigation?

Drip irrigation is the most efficient method of irrigating. While sprinkler systems are around 75-85% efficient, drip systems typically are 90% or higher. ... Drip irrigation (sometimes called trickle irrigation) works by applying water slowly, directly to the soil.

What are the pros and cons of flood irrigation?

Flood irrigation
Low initial investment for equipment is requiredLeast efficient form of irrigation. More water loss from evaporation, infiltration, and runoff
Runoff water can be recycled to improve efficiencyBuilding and taking down levees is labor intensive

Does flood irrigation cause salinization?

At the end of each irrigation (flood, basin and border) cycle, the soil dries out and the salts are concentrated, adversely affecting the crop yield. Frequent irrigation may lower the salinity, but it wastes water.
