Egypt has achieved
record rice yields with varieties that included hybrids
developed locally under an
FAO-led project.
“The world’s highest
national average rice yield in 2005 was 9.5 tonnes per
hectare from Egypt,” the Executive Secretary of the
International Rice Commission, Mr Nguu Nguyen, told an
international scientific conference on sustainable rice
production in Krasnodar, Russia today.
Egypt's average
yields were boosted by the introduction of
newly-developed hybrid varieties such as SK 2034 and SK
2046, which outperformed the best local varieties by
20-30 percent. They were selected from more than 200
hybrid varieties under the FAO-led project, intended to
help Egypt produce more rice with less water and less
land.
Implemented by the
Cairo
Agricultural Research Centre and the Rice Research
and Training Centre (RRTC), the project also helped
train seed breeders and production personnel as well as
extension workers and farmers.
Population growth
The new hybrids are
aimed at increasing Egyptian rice output to resolve a
national production gap stemming from population growth
of 2.2 percent a year combined with increasingly limited
land and water resources. Egypt’s population is set to
increase from a current 75 million to 100 million
inhabitants by 2025. Three million tons of rice will be
needed by 2010 compared with current requirements of 2.8
million tonnes.
Egypt’s appetite for
rice mirrors growing international demand for what is
already the world’s most widely-consumed food. Rice is
the fastest-increasing food crop in Africa for example.
Globally, 618 million
tonnes of rice was produced in 2005 but with world
population growing by more than 70 million a year, an
extra 153 million tonnes will be needed by 2030.
Despite Egypt’s
success, and progress towards a new generation of
varieties, hybrid rice seed production is not a panacea.
There are, for example, a number of countries lacking
technical skills and infrastructure to carry out hybrid
rice seed production programmes.
In the medium term,
increasing rice production in such countries could
require a different approach, one based on introduction
of better crop management practices, Mr Nguyen said.
“The results from
pilot tests in developing countries since 2000 have
demonstrated that very high yield with existing
varieties can be obtained with improved crop management
(ICM),” he noted.
In the Philippines,
for instance, ICM had almost doubled yields of testing
farmers from 4.5 tonnes/ha to over 8 tonnes/ha, he
added.
ICM includes such
practices as setting planting dates to expose crops to
higher solar radiation, optimizing seeding density,
balanced plant nutrition and careful water management.
