AWD technology can bring benefit of Tk 5,500 cr annually

Expanded adoption of Alternate Drying and Wetting (AWD) irrigation technology while farming Boro crop can enhance rice production saving
enormous underground waters to benefit the nation by Taka 5,500 crore annually.
The easiest AWD technology can reduce 5 number irrigations compared to farmers’ general practice, save irrigation water by 30 percent, reduce 30
litres diesel consumption per hectare for irrigation and produce 500 kg more paddy per hectare.The country would be benefited by over Taka 5,500 crore annually for reduced Boro irrigation cost and increased paddy yield in addition to saving underground water if the technology was adopted for farming Boro in 4.78 million hectares land.According to rice scientists and experts, adoption of the technology would reduce lifting of underground water by 30 per cent for irrigation annually saving its reserve, reducing its abnormal lowering and improving ecology, environment and bio-diversity.
Talking to BSS, former Liaison Scientist of International Rice Research Institute (IRRI) for Bangladesh Dr M A Hamid Miah and Associate Director
Agriculture of BRAC International (South Asia and Africa) Dr M A Mazid elaborated the technology.As per Dr Hamid Miah, also former DG of Bangladesh Rice Research Institute (BRRI), the AWD is a simple technology of determining irrigation times in Boro fields. It requires only a 10 cm dia and 25 cm long PVC pipe or hollow bamboo pieces or even waste bottles of cold drinks like coco cola etc.Fifteen cm on one side of the pipe is perforated for easy horizontal movement of water and it is to be installed vertically with its perforated portion under the ground level when soil within the pipe is to be scooped out so that soil at the lower end of the pipe is visible. -BSS, Rangpur,
