Md Rahedul Islam

Alternate wetting and drying (AWD) irrigation technique is an intellectual irrigation schedule management system for rice cultivation. It’s reduced irrigation water use, methane emission, production cost but increases the production and profits. The systems introduce in Bangladesh long time ago but still its implementation rate is very low. This study is an attempt to find out the barriers to adopt AWD irrigation system and suggest the strategies with compare the others rice growing countries. The relevant studies on AWD irrigation have been investigated and explored the barriers and opportunities of AWD irrigation system.
