What are the direct benefits of irrigation?

These include benefits from irrigation-induced crop intensification and diversification towards high-value crops leading to increased crop productivity and overall crop production; benefits derived through non-crop farm and non-farm uses of water including non-consumptive uses of water supplied by irrigation …

What is the main advantage and disadvantage of irrigation agriculture?

Advantages include low costs and minimal labor. A hose and a garden hoe are all it takes to have functioning furrows between vegetable rows. Water stays in the root zone, and foliage stays dry. Drawbacks to surface irrigation include potential overwatering and wasteful runoff.

What are the advantages and disadvantages of furrow irrigation?

Advantages to furrow irrigation include lower initial investment of equipment and lower pumping costs per acre-inch of water pumped. Disadvantages include greater labor costs and lower application efficiency compared to sprinkler and subsurface drip irrigation.

What are the disadvantages of modern method of irrigation?


  • Drip irrigation method is expensive.
  • 2.It requires special technical knowledge for successful operation of this method.
  • 3.In heavy soils, it creates problems of flow and water blockages.
  • Plants are able to get nutritive elements in a very limited area.
  • 5.It is not suitable for every crop.

What are the problems of irrigation in agriculture?

The expansion and intensification of agriculture made possible by irrigation has the potential for causing: increased erosion; pollution of surface water and groundwater from agricultural biocides; deterioration of water quality; increased nutrient levels in the irrigation and drainage water resulting in algal blooms.

How did irrigation improve agriculture?

In areas that have irregular precipitation, irrigation improves crop growth and quality. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies. Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops.

What is the problem with irrigation?

Starting an irrigation cycle too early and/or running an irrigation cycle too long is considered over watering. At the very least this practice wastes water and money. However, overwatering can cause crop damage if done on a prolonged basis.

How irrigation works in the life of farmers nowadays?

To irrigate is to water crops by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies.

Who started irrigation?


What is the main function of irrigation?

Irrigation helps to grow agricultural crops,maintain landscapes, and revegetate distributed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production,including frost protection,suppresing weed growth in grain fields and preventing soil consolidation.

How is irrigation water wasted?

But of the water used for irrigation, only about one-half is reusable. The rest is lost by evaporation into the air, evapotranspiration from plants, or is lost in transit, by a leaking pipe, for example.

Why do rice plants need continuous irrigation?

Continuous irrigation also helps in control of weed, as rice is a Kharif crop and a Kharif crop season tends to grow weeds easily, therefore continuous water supply helps in restriction of weed growth.
