Researchers introduce new technology to speed up cassava multiplication
Scientists are now using
Semi-Autotrophic Hydroponics (SAH) technology to speed up the
propagation of clean cassava planting materials.
Mr Godwin Atser, the Communication
Expert of International Institute of Tropical Agriculture (IITA),
made this known via a news statement on Tuesday in Abuja.
He said that the use of SAH technology
for cassava multiplication was the brainchild of the “Building an
Economically Sustainable Integrated Seed System for Cassava
(BASICS)’’ project.
He said that the SAH technology
involved the use of modified soil, holding plant roots in planting
pots with little water.
“Usually the trays are filled with a
little amount of water and the soil transports the moisture up to the
plant roots; yet the top of the soil remains relatively dry.
“The roots are encouraged to grow
down, and the dry soil on top discourages damp-off and other diseases
caused by excess moisture,’’ he said.
Dr Peter Kulakow, a cassava breeder
with IITA, said that the beauty of the new technology was its rapid
multiplication ratio.
He said that usually when breeders
developed new cassava varieties, the challenge was how to multiply
the varieties and distribute them to farmers.
Kalukwo, however, said that cassava was
a clonal crop while its multiplication was done using stems, adding
that the process would, however, take several years.
He said that this partly explained why
it always took a long time for new improved varieties to be
disseminated at scale to farmers.
“With this technology, these
constraints will be addressed and it will be easier for farmers to
have easy access to new varieties once we develop them.
“Besides addressing the constraints
of slow and low multiplication ratio in cassava seed system, the SAH
technology also produces clean planting materials that are
disease-free,’’ he said.
Kalukwo said that with the adoption of
SAH, the cost of production of the plants was cheaper, when compared
to tissue culture.
Mr Hemant Nitturkar, Project Director
of BASICS said that the technology, which had its origins in
Argentina, would be adapted and perfected in Nigeria under the
project.
He said that the BASICS project was
expected to have a significant impact on the ability of early
generation seed businesses to quickly bring suitable varieties within
the reach of farmers.
He noted that the BASICS project was
also working with National Agricultural Seed Council (NASC) and FERA
(Food and Environment Research Agency) of United Kingdom to the
improve the quality of seed certification system in Nigeria.
Cassava is grown by more than 500
million people in Africa, Asia and Latin America.
Cassava is an important crop in the
efforts of countries to attain food security and create wealth, while
the root crop is a veritable source of animal feeds.
