varieties before flash flood. It is worthwhile to mention here that this kind of action research
needs a continuation for at least three to four years to have a generic result.
Market price
In case of BRRI dhan 45 and BRRI dhan 29 market prices was found higher than the other
varieties (Table 2), production cost was also lower than other varieties. Table 2 shows that
production of BRRI dhan 45, BRRI 29 (popular) and BRRI 29 (research) is higher (about 6
ton/ha) than the other varieties (5.5 tons/ha). Cost of production was found lower in case of
the above mentioned three varieties (average costs Tk.6,700/ton) while it was found above
Tk.7,000 for other varieties.

Based on the overall performance of the research crops (rice) it is recommended that for
addressing the risk of flash flood BRRI dhan 45 and BRRI dhan 29 (with improved
management practice) could be adopted in the research area (haor region).
More details are provided in Annex A.
4.1.2 Pulse crop (Mughbean, Lentil)
Mughbean and Lentil are quite new in the research area. Both the pulses need relatively
shorter time, compared to traditional Boro Rice (Table 3). High and low kanda fallow lands
could be used for the cultivation of these varieties. Extensive motivation among the farmers
to adopt these varieties could bring new dimension in the cultivation practices in the haor
area.
Usually, recession of water from raised kanda lands gets faster and the lands become ready
for agricultural activity 30 to 45 days ahead compared to the rice fields (low lying lands).
Again, the rice fields get inundated at the beginning of flash floods, while raised kanda lands
inundated lately. On the other hand kanda lands are remaining fallow throughout the year.
Therefore these kanda lands are quite feasible for agriculture purposes. The only difficulty in
cultivation in kanda is lack of irrigation facilities. Thus the kanda lands are highly
recommended for the crops which need less irrigation.
Duration
Total cultivation time is less than 140 days for both the crops which can be harvested by
March. However, cold injury caused 15 to 20 days delay in harvesting compared to a normal
year. So it is possible to harvest the crops before flash flood in a normal year.
