Standing crops particularly T-Aman paddy worth about Tk13.1m was damaged in four upazilas of the district due to recent flooding.
The loss of the crops has made farmers frustrated and worried about their food security.
According to sources, water level in Brahmaputra River continues to increase from the first week of the last month.
The river was flowing above the danger level from September 14 submerging the chars (shoals) and the river basin of Sundarganj, Sadar, Fulchhari and Saghata upazilas.
The T-Aman paddy field has already gone under flood water.
As the flood water remained stagnant for a few days, the transplanted seedlings of Aman paddy in a total of 250-hectare land of the upazilas were damaged either fully or partially.
Of the total, 22 hectares of land brought under the varieties of Aman paddy seedlings, particularly the late variety, Ganzia, were fully affected while 228 hectares partially.
The Department of Agriculture Extension estimated the damage of standing crop at TK13.1m.
M Saiduzzaman Sarker, chairman of Mollarchar union of Sadar upazila, said like the farmers of the plains in the upazila, people of his union transplanted seedlings of Aman paddy on the land of both sides of the river during the current season.
The transplanted seedlings grew well and the growers were hopeful to get their desired yields, but their hopes and aspirations were reduced to dust due to the untimely flood that visited the chars and the river basins in mid-September, he added.
M Sahjamal Miah, a farmer of Char Shidhai of the union, said he transplanted the Aman seedlings on three bighas of land during the current season, but his paddy field was damaged totally because of the recent flood.
He added the flood-affected farmers of the union were worried about their food security in the days to come.
Nurunnabi Hossain Sarker, chairman of Kamarjani union of Sadar upazila, said summer vegetables of the union were also damaged due to recent flooding that had caused the farmers to suffer economically.
Under the circumstances, the affected farmers urged the government to take necessary steps for agriculture rehabilitation in coming Robi season so that they could cultivate different crops to recover their loss caused by flood.
