What is the best type of irrigation system? Drip irrigation is the most efficient and appropriate irrigation system. Instead of wetting the whole field surface, water is applied only to the plant root zone. The primary goal of drip irrigation is to apply water at the time when plants need it most and in rates needed for proper plant growth.
What are the basic irrigation methods?
The three main methods of irrigation are surface, sprinkler and drip/micro. Water flows over the soil by gravity for surface irrigation. Sprinkler irrigation applies water to soil by sprinkling or spraying water droplets from fixed or moving systems.
What is the most expensive irrigation?
Expensive Upfront Cost: Sprinkler irrigation systems are the most expensive when it comes to initial installation.
What are the negative impacts of irrigation?
There are many positive impacts of irrigation on the environment. Among the negative impacts which appear in the mentioned spheres prevalent impacts is the danger of waterlogging and salinization of soils and waters, rise in groundwater table, spread of water born diseases, pollution of waters and many others.

How is irrigation used today?
Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops. … Crops are irrigated by several methods: flooding an entire field, channeling water between rows of plants, spraying water through large sprinklers, or letting water drop onto plants through holes in pipes.
Which state has high tank irrigation?
Tank Irrigation is popular in the peninsular plateau area where Andhra Pradesh and Tamil Nadu are the leading states. Andhra Pradesh has the largest area (29%) of tank irrigation in India followed by Tamil nadu (23%).
Why Drip irrigation is costly?
Drip irrigation can reduce a farm’s water consumption by as much as 60 percent and increase crop yield by 90 percent, compared with conventional irrigation methods. But these systems are expensive, particularly in off-grid environments where they cost farmers more than $3,000 per acre to install.
What are three different types of irrigation?
Types of Irrigation Systems
- Surface irrigation. Water is distributed over and across land by gravity, no mechanical pump involved.
- Localized irrigation. …
- Drip irrigation. …
- Sprinkler irrigation. …
- Center pivot irrigation. …
- Lateral move irrigation. …
- Sub-irrigation. …
- Manual irrigation.
What are the positive and negative effects of irrigation?
The effects may be water mining, land/soil subsidence, and, along the coast, saltwater intrusion. Irrigation projects can have large benefits, but the negative side effects are often overlooked. The lower the irrigation efficiency, the higher are the losses.
What are some positive impacts of irrigation?
The original primary purposes of the irrigation project were to reduce poverty, improve food security, create local employment, increase household income and enhance the sustainability of land use.
What are the impacts of irrigation?
reduced agricultural production (Figure 3) • reduced farm income • reduced options for production • reduced access and trafficability on waterlogged land • reduced water quality for stock, domestic and irrigation use • damage to and reduced life of farm structures such as buildings, roads, fences and underground pipes …
What type of irrigation is least efficient?
Surface or flood irrigation is the least efficient manner of irrigation. When a field is flooded, more water than is needed by the plant is applied to the field and water evaporates, seeps into the ground and percolates down to the groundwater, where it can be out of reach of the plant’s roots.
Which is more important in drip irrigation?
Here’s why plants are more productive with drip irrigation: High availability of water and nutrients. Doses of water and nutrients tailored to plant’s development needs. No saturation and good soil aeration.
How many sprinkler heads can I put on one zone?
At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
What are disadvantages of irrigation?
Disadvantages of Irrigation:
- Excessive seepage and leakage of water forms marshes and ponds all along the channels. …
- Excessive seepage into the ground raises the water-table and this in turn completely saturates the crop root-zone.
What is used for irrigation?
Irrigation is the process of watering crops, pasture, and plants by the use of water, which is supplied through pipes, sprinklers, canals, sprays, pumps and other man-made features, rather than purely relying on rainfall.
What is the best mean of irrigation?

What are the necessities of irrigation?
Thus, the necessity of irrigation is as follows:
- Less Rainfall. When the total rainfall is less than needed for the crop, artificial supply is necessary. …
- Non-uniform Rainfall. …
- Growing a number of crops during a year. …
- Growing perennial crops. …
- Commercial crop with additional water. …
- Controlled water supply.
Why is irrigation bad?
Because irrigation systems deal with redirecting water from rivers, lakes, and underground sources, they have a direct impact on the surrounding environment. … Increased evaporation in irrigated areas can cause instability in the atmosphere, as well as increase levels of rainfall downwind of the irrigation.
Which areas have high levels of irrigation?
Most of the canal irrigation is in the canal network of Ganges-Yamuna basin mainly in the states of Punjab, Haryana, and Uttar Pradesh and somewhat in Rajasthan and Bihar, while small local canal networks also exist in the south in Tamil Nadu, Karnataka, and Kerala, etc.
Why is irrigation important?
Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation.
