What is culturable command area?
Cultivable Command Area (CCA): The area which can be irrigated from a scheme and is fit for cultivation.
How do you calculate command area?
Here is the Formula for finding Culturable Command Area : Gross Command Area = Cultivable Command Area + Uncultivable Area.
What is a command area used for?
4.2 Command Area. The command area, CA, of a water source is the extent of area which can be reliably irrigated from that source. Reliable irrigation means that the availability of water is always larger than or equal to the irrigation need of a scheme.
What is GCA and CCA?
Gross command area (GCA): The total area lying between drainage boundaries which can be commanded or irrigated by a canal system. G.C.A = C.C.A + unculturable area 3. Water Tanks: These are dug areas of lands for storing excess rain water.
What is culturable waste land?
Culturable Waste Land: This includes land available for cultivation, whether taken up or not taken up for cultivation once, but not cultivated during the last five years or more in succession including the current year for some reason or the other .
What percentage of gross commanded area is taken as culturable command area?
The gross commanded area for a distributary is 6000 hectares, 80% of which is culturable irrigable.
What is command area and catchment area?
command area is a part of catchment area. But catchment area is the area between the boundary line that is connected by highest elevation points on a specific area under observation. This may or may not be the command area. But command area is which area comes under culturable area.
What is crop period?
Crop Period: The time period that elapsed for the instant of the sowing of the crop to the instant of its harvesting is called crop period. Base Period: The time between the first watering of a crop at the time of its sowing to its last watering before the harvesting is called the base period or the base of the crop.
What is the gross command area and culturable command area?
This Gross Command Area (GCA) includes cultivable land as well as barren land, forests, houses, wasteland, roads etc. Cultivable Command Area is that part of Gross Command Area, which is fit for cultivating crops. So, cultivable area excludes forest and barren land from the Gross Command Area.
What is the difference between command area and catchment area?
What is the use of drip irrigation?
What is drip irrigation? Drip irrigation is the most efficient water and nutrient delivery system for growing crops. It delivers water and nutrients directly to the plant’s roots zone, in the right amounts, at the right time, so each plant gets exactly what it needs, when it needs it, to grow optimally.
What do you mean by culturable?
Definition of culturable : capable of culture : cultivable.
What is culturable command area (CCA)?
Culturable Command Area is the area in which a crop is grown at a particular time or crop season. It is denoted by CCA. Uncultivable areas are excluded from GCA to obtain CCA. The uncultivable area includes barren lands, forests, etc. The culturable Command Area can be of two types.
What is the culturable commanded area?
The culturable commanded area is that portion of the gross commanded area which is culturable or cultivable. Thus culturable commanded area may be obtained by subtracting the unculturable area from the gross commanded area. The culturable commanded area may be subdivided into the following two categories.
What do you mean by curable command area?
The area cultivated land in the gross command of an irrigation system is called curable command area (CCA) and includes all land of the gross command on which cultivation possible. At any given time, however, all the cultivable land may not be actually under cultivation.
What is the difference between cultivable area and uncultivable area?
Cultivable Command Area is that part of Gross Command Area, which is fit for cultivating crops. So, cultivable area excludes forest and barren land from the Gross Command Area. What is left is uncultivable These terms are mainly used in canal irrigation engineering.
