How is irrigation intensity calculated?
Irrigation Intensity It is the ratio of gross irrigated (total) area to the net irrigated area expressed as a percentage.
What is crop intensity?
Cropping intensity is defined as the number of crops a farmer grows in a given agricultural year on the same field (Raut et al., 2011) and is another means for intensification of production from the same plot of land.
How would you describe irrigation?
Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected. There are many types of irrigation systems, in which water is supplied to the entire field uniformly.
What is the annual intensity of irrigation AII?
What is the Annual Intensity of irrigation (AII)? Explanation: The AII is the sum total of intensities of irrigation of all the seasons of the year. IT can also be defined as the percentage of CCA which may be irrigated annually. It is thus obtained by dividing the gross irrigated area by the CCA.
What is meant by sprinkler irrigation?
Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground.
What is rotational intensity?
Rotation intensity is the level of demand for water created by the rotation. Cropping more frequently and including a larger proportion of high water using crops in a rotation will increase intensity. The level of water use by the system should match the water available under “normal” conditions.
What is cropping intensity with example?
Cropping intensity is defined as the seasonal area cropped divided by the. command area. If for example the 75,000 acres is the cropped area. during Rabi out of total command area of 100,000 acres, then CI for Rabi. is 75 \% and if 50,000 acres is the cropped area during Kharif out of same.
What is water irrigation?
irrigation and drainage, artificial application of water to land and artificial removal of excess water from land, respectively. Some land requires irrigation or drainage before it is possible to use it for any agricultural production; other land profits from either practice to increase production.
What is irrigation water management?
Irrigation water management is the process of determining and controlling the volume, frequency and application rate of irrigation water in a planned, efficient manner .
What is base period in irrigation?
Base Period for a crop refers to the whole period of cultivation from the time when irrigation water is first issued for preparation of the ground for planting the crop, to its last watering before harvesting.
What is water use intensity (WUI)?
Water Use Intensity (WUI) generally refers to the rate at which water is used in a given area. It is an indicator of how much water your building requires during its occupation.
Irrigation water management is the act of timing and regulating irrigation water applications in a way that will satisfy the water requirement of the crop without the waste of water, soil, plant nutrients, or energy.
Can the yearly intensity of irrigation be more than 100\%?
However the yearly intensity of irrigation will be equal to 66.66 + 41.67 = 108.33\%. Thus yearly intensity of irrigation can be more than 100 \%
What is the definition of area of irrigation?
A measurement of the volume of water applied to landscape in a given time. (In the United States, usually expressed in inches per week. Its metric equivalent is centimeters per week.) The area a part-circle sprinkler irrigates, expressed in degrees of a circle.
