Aus and Aman seed crop fields of the Seed Production Farm run by Bangladesh Agriculture Development Corporation (BADC in the district have been submerged by floodwaters.
The farm authorities are trying to drain out the stagnant water from the submerged seedbed fields, said an official of the farm.
According to the farm in Madhupur, about 250 acres out of 345 acres of cultivated fields of the farm in Kakraid area under the upazila have been inundated in floodwaters.
The paddy fields have been flooded due to an increase in water levels of the Banshi river and Guja Khal (canal) that flows through the farm area because of the heavy rain and the rush of water from upstream since July 8.
As a result, the seed crops of BRRI-48 variety of Aus paddy on 45 acres of land have been damaged as it went under floodwaters.
Although the Aman seedbeds were saved by the farm authorities, 10 acres of planted BRRI-87 verity and 12 acres of BINA-17 verity were destroyed by floodwaters.
It was targeted to produce 345 tonnes of paddy from 242 acres of land during the current season. However, it was possible to plant paddy on only 60 acres of lands so far.
Sanjay Roy, deputy director (farm) of Seed Production Farm in Madhupur, said they were trying to drain out stagnant water from the submerged seedbed fields.
"We hope the floodwater will recede within the next 10 to 15 days and we will try to achieve the production target by planting seedlings on the fields," he added.
On the other hand, according to the Department of Agricultural Extension (DAE) in Tangail, different crops including Aus and Aman, vegetables and lemon of total 12,198 hectares of lands have been damaged by floodwaters in 11 affected upazilas of the district during the second phase of flood from July 12.
Earlier, 3,639 hectares of different crops including bona (broadcast) Aman, seedbeds of transplanted Aman, Aus paddies and vegetables have been fully damaged in six upazilas in the first phase of flood during the first week of July.
