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...
