This is one of 280 summaries describing key outputs from the projects
run by DFID's 10-year Renewable Natural Resources Research Strategy
Principally based on Projects R7471, R8234 and R8412. New ways to
control weeds and plant rice using direct-seeding have great potential
to increase rice harvests in Bangladesh. At the moment, one-third of
farmers lose half a tonne of rice per hectare because of weeds. Now, a
range of cost-effective weed management practices have been validated,
which include applying herbicides or using a manual rotary weeder.
Yields are the same or better than with normal hand-weeding, but costs
are 30-45% less. Direct-seeding has also proved valuable in
drought-prone areas. It gives earlier rice harvests, allows farmers to
grow a second crop, and reduces outlays on irrigation water and labour.
Extensionists and NGOs are already spreading the word, and training
manuals, leaflets and posters for pesticide-dealers' stores are
