Survey findings on deepwater rice (DWR) from six districts of Bangladesh-Dhaka, Tangail, Mymensingh, Jamalpur, Faridpur, and Sylhet - are reported. Information on cultivated area and DWR area, culture type, pattern and depth of flooding, variety, and yield was collected using a two-stage random sampling technique. Faridpur District has the largest area under DWR (53%), followed by Dhaka (43%), Tangail (37%), Sylhet (12%), Mymensingh (11%), and Jamalpur (8%), DWR in Dhaka, Faridpur, Jamalpur, and Tangail is grown mostly with aus rice in a mixed cropping scheme (57-62%). In Mymensingh and Sylhet, DWR is mostly broadcast. Floodwater inundation starts in mid-May with a peak in July, and recession starts in mid-September, with maximum recession taking place in November. Depth of flooding varies from 0.3 to 6.0 m in these districts, with the maximum depth attained in August. The number of varieties grown varies from 38 to 162, the popular ones being Chamara, Bhawalia Digha, Laksmi Digha, Khama, Lakhi, Badal, and Bazail. Yield varies from 1.2 to 1.9 t/ha with broadcast seeding, and from 0.9 to 1.6 t/ha in mixed cropping, with aus rice.
