The dominant food crop of Bangladesh
is rice, accounting for about 75 percent of agricultural land use (and 28
percent of GDP). Rice production increased every year in the 1980s (through
1987) except FY 1981, but the annual increases have generally been modest,
barely keeping pace with the population. Rice production exceeded 15 million
tons for the first time in FY 1986. In the mid-1980s, Bangladesh was the fourth
largest rice producer in the world, but its productivity was low compared with
other Asian countries, such as Malaysia and Indonesia.
It is currently the world's sixth-largest producer. Highyield varieties of
seed, application of fertilizer, and irrigation have increased yields, although
these inputs also raise the cost of production and chiefly benefit the richer
cultivators.
The cultivation of rice in
Bangladesh varies according to seasonal changes in the water supply. The
largest harvest is aman, occurring in November and December and accounting for
more than half of annual production. Some rice for the aman harvest is sown in
the spring through the broadcast method, matures during the summer rains, and
is harvested in the fall. The higher yielding method involves starting the
seeds in special beds and transplanting during the summer monsoon.
The second harvest is aus, involving traditional strains but more often
including high-yielding, dwarf varieties. Rice for the aus harvest is sown in
March or April, benefits from April and May rains, matures during in the summer
rain, and is harvested during the summer.
With the increasing use of irrigation,
there has been a growing focus on another rice-growing season extending during
the dry season from October to March. The production of this boro rice,
including high-yield varieties, expanded rapidly until the mid-1980s, when
production leveled off at just below 4 million tons. Where irrigation is
feasible, it is normal for fields throughout Bangladesh to produce rice for two
harvests annually. Between rice-growing seasons, farmers will do everything
possible to prevent the land from lying fallow and will grow vegetables,
peanuts,
pulses,
or oilseeds
if water and fertilizer are available.
