What is the modern method of irrigation?
The widely used methods of irrigation are surface, sprinkling, subirrigation, intrasoil, and mist irrigation.
Soil wetting and salt leaching are the principal purposes of surface irrigation.
In sprinkler irrigation both soil and air are wetted, besides frost prevention and application of fertilizers and herbicides..
What is modern irrigation system?
Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops. … Letting water drop onto plants through holes in pipes, known as drip irrigation, is considered one of the most efficient methods of irrigation. Drip irrigation focuses the water onto the plant itself.
How do I choose an irrigation system?
With that in mind, here is a look at five things to consider in getting water to your crops:Soil type. The type of soil in an area can affect not only the type irrigation method used but also the irrigation run times. … Land topography. … Local weather patterns. … Type of crops grown. … Water quality.
What is the best type of irrigation?
Drip Irrigation This system is good for a small yard or for watering individual plants. Drip irrigation is highly effective at supplying one to four gallons of water per hour directly to the soil. The advantage of drip irrigation over sprinklers is that there is little water loss due to evaporation or runoff.
Who invented irrigation?
King MenesThe first major irrigation project was created under King Menes during Egypt’s First Dynasty. He and his successors used dams and canals (one measuring 20 km) to use the diverted flood waters of the Nile into a new lake called lake “Moeris.”
Which irrigation method is the most efficient?
drip irrigationFor watering large areas of farmland, drip irrigation is the most efficient irrigation system for reducing water and fertilizer loss. By filtering the water down through the soil and into the root system, some of the water percolates down into the groundwater system to be reused for irrigating in future years.
Which irrigation system is least efficient?
flood irrigationSurface 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.
What are the two types of irrigation?
Types of Irrigation SystemsSurface 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 3 main types of irrigation?
There are three main types of irrigation systems: surface, overhead and drip (see Table 1).
Which is the best method of irrigation and why?
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.
Which country has best irrigation system?

Which is better drip or spray irrigation?
In general, spray irrigation systems are better for covering larger areas. Typically these areas are home to plants that do not have very precise water requirements. Drip irrigation, on the other hand, tends to be more precise in administering particular quantities of water over a given period of time.
What is fertigation system?
Introduction. Fertigation is the application of fertilizer with irrigation water. This article will discuss fertigation using drip irrigation and commercial fertilizers that can be used in certified organic systems.
Which type of irrigation is used in India?
There are various types of systems of irrigation practices in different parts of India. Irrigation in India is carried on through wells, tanks, canals, perennial canal, multi-purpose river valley projects.
What is the best method of irrigation for rice?
Sprinkler or drip irrigation are preferred above surface irrigation on steeper or unevenly sloping lands as they require little or no land levelling. An exception is rice grown on terraces on sloping lands. Climate: Strong wind can disturb the spraying of water from sprinklers.
