RANGPUR, July 13, 2015 (BSS) - Tens of thousands of farmers have
already completed preparing seedbeds for expanded cultivation of
flood-tolerant variety rice during this Aman season after getting
repeated bumper productions in the previous seasons.
Excellent yield of flood tolerant rice in the previous seasons has
made the farmers enthusiastic as the growing plants survived
submergence for over two weeks to resume normal growth after recession of floodwater.
According to farmers, growing plants of flood tolerant BRRI dhan51,
BRRI dhan52, BINA dhan11 and BINA dhan12 rice survived submergence for two weeks, or even more, during floods to ultimately give better yield in the previous seasons.
Basing on their success, the framers have been showing keen
interests in cultivating flood tolerant rice varieties in the
low-lying areas to enhance rice output for attaining sustainable food
security under changing climatic conditions.
Talking to BSS, Farmer Lal Mian of village Patrokhata in Kurigram
said his growing plants of BINA dhan11 successfully sustained 24-day
submergence at a stretch last season to resume normal growth after
recession of floodwater.
"After one week of transplantation since August 9 in 2014,
floodwater inundated my growing BINA dhan11 plants along with all
other growing traditional variety Aman rice fields in the surrounding
area on August 15 then," he said.
He said floodwater receded after 24 days of inundation from his
field on September 9 last year when only little sign of transplanted
BINA dhan11 seedling remained in rotten state and the traditional
variety Aman fields were completely damaged all-around.
"After one week since recession of floodwater, the rotten hills
(remains) of transplanted seedling started growing again giving birth
to new tillers and my field again turned green miraculously within
next two weeks," he said.
"Finally, I got 4.5 tonne yield per hectare of BINA dhan11 rice
last year," said Lal Mian adding that the phenomenon soon created huge
enthusiasm among local farmers as all other traditional Aman rice
plants were totally damaged in surrounding areas.
Farmers Beauty Begum of village Kanipara and Profulla Roy of
village Purbo Echlee in Rangpur said they cultivated flood tolerant
BINA dhan12 and BRRI dhan52 rice on their lands respectively last
"We got average yield between 4.5 to 5 tonne per hectare then
despite growing plants of the flood tolerant rice varieties remained
submerged for 18 days to resume normal growth after recession of
floodwater," they said.
Farmer Suvanol Chandra of village Sankibhanga in Gaibandha got 4.28
tonne yield per hectare of BINA dhan11 last season and despite the
growing rice plants remained submerged under floodwater for 19 days.
Farmers Mostaq Ahmed and Boytullah of Lalmonirhat said growing
plants BRRI dhan52 rice remained submerged for two weeks last year and they also get excellent yield rate at the end.
Farmers Shamsul Haque of Nilphamari, Nattya Roy of Rangpur, Abdul
Haque of Kurigram and Israrul Haque of Lalmonirhat narrated their
experience in farming different flood tolerant rice varieties to get
excellent yield even after submergence.
They narrated as how their growing plants of flood tolerant BRRI
dhan51, BRRI dhan52, BINA dhan11 and BINA dhan12 rice resumed normal growth after more than two weeks of submergence in the low-lying areas last season.
"Finally, we got 3.5 to 4.5 tonne yield per hectare of these rice
during the last Aman season when the traditional variety Aman rice
were totally damaged in the surrounding areas," they added.
The Stress Tolerant Rice for Africa & South Asia (STRASA) Project,
being funded by Bill & Melinda Gates Foundation, has been extending
assistance for cultivating stress tolerant rice through the International Rice Research Institute (IRRI) with GO-NGO collaboration.
Project Scientist (Country Manager) of STRASA-IRRI Project in
Bangladesh Dr MA Bari told BSS that 43 thousand tonnes seed were
distributed among farmers in the country to further expand cultivation
of flood tolerant rice this season under the project in Bangladesh.
