What is irrigation and its methods?
Irrigation is the process of supplying water to the land at regular intervals by means of canals and other artificial methods, to enhance agricultural growth and maintain the landscape during the periods of less average rainfall..
Who invented irrigation?
EgyptIt is widely believed that irrigation was being practiced in Egypt at about the same time (6), and the earliest pictorial representation of irrigation is from Egypt around 3100 B.C. (1). In the following millennia, irrigation spread throughout Persia, the Middle East and westward along the Mediterranean.
Is it important to increase the area under irrigation Why?
Yes, it is important to increase the area under irrigation because water is very essential for agriculture. In India, the rainfall is unevenly distributed in the country and if rainfall is less, then production will be low, and they will be only able to grow one crop in a season.
What are the sources of irrigation Class 9?
Answer. The main sources for irrigation water are groundwater from wells, surface water, drainage ponds, rain and municipal water.
What are weeds Class 9?
Weeds: Weeds are unwanted plants in the cultivated field, for example, Xanthium (gokhroo), Parthenium (gazar ghas) and Cyperinus rotundus (motha). They compete for food, space and light. Weeds take up nutrients and reduce the growth of the crop.
What is irrigation class 9th?
Irrigation. Irrigation. The process of watering plants to ensure that crops get enough quantity of water atproper phase during their growing season to increase the expected yields of any crop is called irrigation.
What are the two method of irrigation?
Two means of irrigation systems which conserve water are Drip system and sprinkler system.
What are the modern methods of irrigation Class 8?
The modern methods of irrigation include – surface irrigation, drip irrigation, sprinkler irrigation, subsurface irrigation.
What are the 3 main types of irrigation?
Various irrigation methods have been developed over time to meet the irrigation needs of certain crops in specific areas. The three main methods of irrigation are surface, sprinkler and drip/micro.
What is an example of irrigation?
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. … This water was used for drinking, washing, and irrigation. Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops.
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.
What are fertilizers Class 9?
Fertilizers are chemical substances supplied to the crops to increase their productivity. … The fertilizers contain the essential nutrients required by the plants, including nitrogen, potassium, and phosphorus. They enhance the water retention capacity of the soil and also increase its fertility.
What is irrigation short answer?
Supply of water to crops at appropriate intervals is called irrigation. … When water is allowed to flow under high pressure with the help of a pump, it gets sprinkled on the crops. †’ Drip system: In this system, water is delivered at or near the roots of plants, drop by drop.
What are two methods irrigation?
The process of watering the crops is called irrigation. Two methods of irrigation are: (i) Sprinkler system : This system is used on the uneven land where less water is available. … (ii) Drip irrigation: This system is used to save water as it allows the water to flow drop by drop at the roots of the plants.
What is the traditional method of irrigation?
The traditional methods of irrigation include the following: Check Basin Method. Furrow Irrigation Method. Strip Irrigation Method. Basin Irrigation Method.
Where is spray irrigation used?
An irrigation sprinkler (also known as a water sprinkler or simply a sprinkler) is a device used to irrigate agricultural crops, lawns, landscapes, golf courses, and other areas. They are also used for cooling and for the control of airborne dust.
What is meant by irrigation?
Irrigation is the artificial process of applying controlled amounts of water to land to assist in production of crops. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
What are the sources of irrigation?
The main sources for irrigation water are groundwater from wells, surface water, drainage ponds, rain and municipal water. Drilled wells are a clean source of water for many greenhouse operations however, the water yield from drilled wells is usually limited.
