原始语种摘要: Abstract(#br)The drought prone North-West Bangladesh is vulnerable to the impacts of climate change, particularly because of less water availability in the dry period and high water requirement for crop production. Improved understanding of recent changes in crop water demand in the dry season is important for the water resources management in the region. A study was carried out to determine the potential impacts of recent climate change during last three decades on trends of water requirements of Boro rice. The reference crop evapotranspiration (ET o ), potential crop water requirement (∑ET C ), effective rainfall during the crop growing period (ER), potential irrigation requirement for crop evapotranspiration (∑ET C ER) and net irrigation...
