Management of Rice in
Flood-Prone Areas
A
bout six million hectares of lowlands in eastern India are subjected to
annual flooding. Farmers in these areas had been using indigenous
technologies to grow rice. Improved practices are now available to
farmers for growing better crops.
Rice in flood-prone areas is grown in
two situations:
deepwater situation (stagnant
flood); and
rainfed shallow lowlands (with
flash flood).
Deepwater situation (stagnant flood) (DWS)
Occurrence of flood and inundation is a regular feature in the deepwater
situation throughout the monsoon period.
Rice culture options in DWS
DEEPWATER RICE
Deepwater rice varieties are either
sown directly in the dry soil during
the dry season (February-March) or
transplanted in fields in May before
the floodwater accumulates.
BORO RICE
After water recedes, Boro rice is
grown from November – December
to April – May.

Direct seeding in dry fields
