RAJSHAHI, Sept 29, 2025 (BSS) – Expanded adoption of Alternate Wetting and Drying (AWD) irrigation method throughout Boro rice farming can save minimal 30 % irrigation water together with growing the rice output.
Adoption of AWD expertise with correct agronomic administration reduces the variety of irrigation saving 30 % water and 30 litres diesel and electrical energy for irrigation to supply 500 kg extra Boro paddy per hectare of land.
The views have been disseminated by agricultural scientists and consultants in a outcome sharing workshop titled “Sustainable Rice Production: Pilot test water-sensor-IOT irrigation and low carbon rice using AWD” held at Grand River View Hotel in Rajshahi metropolis right now.
Asian Development Bank (ADB) and DASCOH Foundation collectively organized the workshop technically supported by International Rice Research Institute (IRRI), Bangladesh Rice Research Institute (BARI), Nippon Koei and Pabna University of Science and expertise (PUST).
Executive Director of Barind Multipurpose Development Authority (BMDA) Tarikul Alam addressed the workshop as chief visitor, whereas Deputy Director of Department of Agricultural Extension Dr Farida Parveen and Prof Chowdhury Sarwar Jahan from the Department of Geology and Mining at Rajshahi University spoke as particular company.
Dr Takashi Yamano, Principal Economist of Bangladesh Resident Mission, ADB, presided over the assembly.
BMDA Additional Chief Engineer Dr Abul Kashem, Country Director of Sustainable Agriculture Foundation Bangladesh Farhad Jamil and Prof Niamul Bari from the Department of Civil Engineering at Rajshahi University of Engineering and Technology additionally spoke, disseminating their experience on the problem.
Chief Executive Officer of DASCOH Foundation Akramul Haque moderated the occasion.
In the technical session of the workshop, IRRI Bangladesh Consultant Dr (*30*) Mondal illustrated the results of pilot check IOT-based sensible irrigation programs and family survey on low-carbon rice farming utilizing AWD, whereas BRRI Senior Scientific Officer Dr Mozammel Haque targeted on the methane emission discount by AWD system in rice farming in Bangladesh.
Associate Professor Dr Rahedul Islam from PUST talked in regards to the outcome on multi-sensors based mostly measurement of irrigation water use and GHG emission from AWD and non-AWD practices rice paddy discipline, whereas Shuta Sato from Nippon Koei highlighted the JCM mechanism and Nippon Koei’s experience and expertise in AWD implementation.
They instructed the assembly that the AWD method would outcome in a fivefold discount in requirement for water and save 30 litres of diesel used for irrigation and produce an extra 500 kilograms of paddy per hectare.
AWD is a water-saving expertise that farmers can apply to cut back their irrigation water consumption in rice fields with out lowering its yield.
In AWD, irrigation water is utilized just a few days after the disappearance of the pond water. Hence, the sphere will get alternately flooded and non-flooded.
In AWD, a paddy discipline is made moist and dried intermittently, which means watering solely when needed.
The variety of days of non-flooded soil between irrigations can differ from one to greater than 10 days relying on the variety of components comparable to soil kind, climate and crop progress stage.
The farmers are instructed to domesticate wheat as an alternative of solely Irri-Boro paddy in the drought-prone dry areas.
Tarikul Alam instructed the assembly that the BMDA will work to advertise the AWD method in the Barind space to lower its regularly mounting strain on underground water with integration of ADB and DASCOH basis.
