Water Requirements of Crops topics include: Water distribution techniques in fram, crop and base period, duty and delta of crop, crop season and indian agriculture, irrigation water optimum utilisation, irrigation efficiencies, evapotranspiration consumptive use, effective rainfall, consumptive use estimation and soil moisture irrigation relationship. The amount of water crops need depends on their characteristics, management practices, and environmental demands.  Here are some examples of water requirements for different crops: Rice: 3,000–5,000 liters per kilogram Cotton: 22,500 liters...

Water Requirements of Crops topics include: Water distribution techniques in fram, crop and base period, duty and delta of crop, crop season and indian agriculture, irrigation water optimum utilisation, irrigation efficiencies, evapotranspiration consumptive use, effective rainfall, consumptive use estimation and soil moisture irrigation relationship.

The amount of water crops need depends on their characteristics, management practices, and environmental demands. 

Here are some examples of water requirements for different crops:
Rice: 3,000–5,000 liters per kilogram
Cotton: 22,500 liters per kilogram
Sugarcane: 1,500–2,500 mm of rainfall or water to complete its growth cycle, and 1,500–3,000 liters per kilogram
Soya: 900 liters per kilogram
Sorghum: 450–650 mm
Maize: 500–800 mm
Groundnut: 500–700 mm
Wheat: 450–650 mm
Tobacco: 400–600 mm
Tomato: 600–800 mm 

Crops with medium water requirements include sorghum, maize, wheat, and cotton. Crops with high water requirements include rice, sugarcane, and bananas. Crops with low water requirements include millets, grain legumes, and oil seed crops.
