The fourth phase of flood in the northern region may damage large quantities of paddy and winter vegetables, feared farmers and experts.
As a result, the market of such seasonal agricultural goods may remain unstable and the price may shoot up, they added.
The officials at the Department of Agriculture Extension (DAE) in different flood-hit districts were encouraging farmers to re-cultivate vegetables after floodwater recedes.
This year, the first phase of flood hit the region in June due to heavy downpour and onrush of water from upstream.
Subsequently, the second and third phases hit the area in the following month. Finally, the region witnessed the fourth phase last week.
The water level on the Brahmaputra, the Jamuna and the Padma rivers were on the rise that might continue for the next 48 hours, said a bulletin of Flood Forecasting and Warning Centre (FFWC).
"The major rivers of the Upper Meghna Basin in the North-Eastern region of the country are in falling trend, which may continue in next 48 hours," said the bulletin that was released at 9:00am yesterday.
At least seven rivers were flowing above danger level yesterday at eight stations across the country, read the FFWC bulletin.

Besides, moderately heavy rainfalls may occur at isolated places over the country, said the BMD forecast that was released at 6:00pm yesterday.
