A project implemented in six Upazilas under six districts of Rajshahi and Rangpur divisions in Bangladesh to assess the impact of AWD technique on rice production, where totally 108 farmers were selected as the participant of this study included Project farmers/AWD technique followers(54) and non-project farmers/conventional practice followers(54). Trial’s in two seasons (Boro 2012 and 2013) were conducted in each nine selected locations of six Upazilas under six districts, where farmers cultivated six selected rice varieties. The data were collected by simple random sampling model, while Focus Group Discussion (FGD) were held by the researchers and collected data were analyzed by using t-tests. Findings revealed that, frequencies of irrigation used in AWD technology practice were lower than those of conventional technique. However, AWD practice required 22.0 per cent less irrigation water than conventional technique. It implied that the use of AWD practice increased (6.0%) yield of rice compared to the farmers’ traditional practices. The findings and suggestions for this study might be useful for policy makers and planners in formulating and redesigning the water management strategies. There may have wide range circulation of AWD technique in all over the country demonstrating its importance on irrigation water savings, increased yield of rice and reduced insect and pest infestations especially in the Boro season.
