Amount of water used every day for irrigation per acre for groundnut
Answers
Explanation:
It depends on the delta of a crop.
Suppose you have field of sugarcane so the delta (Amount of water required by crop to grow upto it's maturity in cm) of that crop wil be more so more water will be needed to irrigate the field vice-versa.
But still you want to know you can find out by:
Quantity of water(1acre)= Area(cm2)×delta of crop(cm)+certain loss(evaporation loss,conveyance loss etc) approx.
Not accurate but you can find this way.

Explanation:
How Completely depends on loads of factor. But just to give you a synopsis: for water intensified crops like paddy, sugarcane, etc with flood irrigation at every 3 day interval an acre would require 20,000–40,000 liters.
But water requirement would depend on these following factors:
Crop: This is the main subject determining the water requirement. Water intensified paddy crop would require 20,000–40,000 litres every 3 days. Generally trees require lesser water than paddy crops.
Climate: In tropical and subtropical climate especially in arid regions, irrigation interval is higher. Every 2 days or 3 days. In slightly moist conditions the interval increases to 4–5 days.
Soil condition: There’re various soil types like loam, clay, sandy, clay loam, sand loam etc. these determine the crop types and also alters the irrigation system thus determining the water requirement.
Soil permeability: The permeability of the soil determines the water retention capacity which also called water conductivity. High permeability means the water is drained out very quickly thus decreasing the irrigation interval: From 4–5 days, it becomes 2–3 days. But on the other hand if the soil permeability is low. Then the water gets stagnated thus rotting the root. So it has to be moderate and determines the cultivable crops. Which in turn determines the water requirement for irrigation.
Irrigation type: There’re various irrigation types, namely:
Flood irrigation: this uses the most water. Generally for crops like paddy, sugarcane, maize, wheat, etc. cheapest but very less efficient
Sprinkler/Rain Gun’s: this uses only 30–50% of water used in flood irrigation. This is the best alternative for crops like paddy, sugarcane, maize etc. this is needs some investment but very effective
Drip irrigation: This uses only 10–20% of water compare for flood irrigation. This basically supplies the amount of water required for the plant very effectively. This is best suitable for trees and shrubs but it’s not s major success for paddy, sugarcane, maize etc. this has a lot of investments but very very efficient
Other alternative methods: There’re other alternative and creative methods like, wick irrigation, bottle irrigation, green house effect irrigation, mist/spray irrigation etc and water conversation methods like Hydroponics, aquaponics, Polyhouse etc. which uses very less water.
