Researchers employ SAH technology to speed up multiplication of cassava planting materials
Scientists working on cassava breeding are now using the Semi-Autotrophic Hydroponics (SAH) technology to rev up the propagation of clean cassava planting materials.
The SAH involves the use of modified soil which holds 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.
Dr Peter Kulakow, a cassava breeder with the International Institute of Tropical Agriculture (IITA), said the beauty of technology was its rapid multiplication ratio.
Usually when breeders develop new cassava varieties, the challenge is how to multiply and disseminate to farmers. Hence cassava is a clonal crop and multiplication is done using stems, this process takes several years.
Dr Kulakow said this explains in part why it takes long 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,” he explained.
But 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. The cost of production of the plants is cheaper using SAH when compared to tissue culture, Dr Kulakow said.
The SAH technology in cassava is a brainchild of the project: Building an Economically Sustainable Integrated Seed System for Cassava (BASICS).
Hemant Nitturkar, Project Director of BASICS explained that once the technology, which is adopted from Argentina, is adapted and perfected in Nigeria by the Project, it is expected to have a significant impact on the ability of early generation seed businesses to quickly bring suitable varieties within reach of farmers.
The BASICS project is also working with National Agricultural Seed Council (NASC) and Fera of United Kingdom to improve the quality certification system in Nigeria.
Grown by more than 500 million people in Africa, Asia, and Latin America; cassava is an important crop for both food security and wealth creation. The root crop is a source of commercial animal feed, fiber for paper and textile manufacturers, and starch for food and pharmaceutical industries.
US car giant Ford on Wednesday announced 4,000 more job cuts in Europe, mostly in Germany and Britain, in the latest blow to the continent’s beleaguered car industry.
“The company has incurred significant losses in recent years,” Ford said in a statement, blaming “the industry shift to electrified vehicles and new competition”.
The move will affect 2,900 jobs in Germany, 800 in the UK and 300 in western Europe by the end of 2027, a Ford spokesman told AFP.
“It is critical to take difficult but decisive action to ensure Ford’s future competitiveness in Europe,” said Dave Johnston, Ford’s European vice-president in the statement.
The company also said it was adjusting the production of its Explorer and Capri models, resulting in reduced hours at its Cologne plant in the first quarter of 2025.
Europe’s car industry has been plunged into crisis by high manufacturing costs, a stuttering switch to electric vehicles and increased competition in key market China.
Germany’s Volkswagen has been among those hardest hit, announcing in September that it was considering the unprecedented move of closing some factories in Germany.
“The European automotive industry is in a very demanding and serious situation,” Volkswagen CEO Oliver Blume said at the time.
Ford had already announced in February 2023 that it was planning to cut 3,800 jobs in Europe, including 2,300 in Germany and 1,300 in Britain.
The company said then it was planning to reduce the number of models developed for Europe, concentrate on the profitable van segment and speed up the transition to electric vehicles.
Ford currently has around 28,000 employees in Europe with 15,000 in Germany, according to the company’s works council.
President Bola Tinubu has approved the dissolution of the Governing Council of Nnamdi Azikiwe University (UNIZIK), Awka, Anambra State, and the removal of the institution’s Vice-Chancellor, Prof. Bernard Ifeanyi Odoh, and Registrar, Mrs. Rosemary Ifoema Nwokike.
The council, chaired by Ambassador Greg Ozumba Mbadiwe, comprised five other members: Hafiz Oladejo, Augustine Onyedebelu, Engr. Amioleran Osahon, and Rtd. Gen. Funsho Oyeneyin.
A statement released on Wednesday by presidential spokesperson, Bayo Onanuga, revealed that the council was dissolved following reports of procedural violations in appointing the vice-chancellor.
According to the statement, the council had allegedly appointed an unqualified candidate, disregarding due process, which triggered tensions between the university’s Senate and the council.
The Federal Government expressed dismay over the council’s actions, emphasizing the need for adherence to the university’s governing laws in decision-making.
“The council’s disregard for established rules necessitated the government’s intervention to restore order to the 33-year-old institution,” the statement noted.
In a related development, President Tinubu also approved the dismissal of Engr. Ohieku Muhammed Salami, the Pro-Chancellor and Chairman of the Governing Council of the Federal University of Health Sciences, Otukpo, Benue State.
Salami was accused of suspending the university’s Vice-Chancellor without following the prescribed procedures, a move the Federal Ministry of Education had previously directed him to reverse.
Despite the Ministry’s directives, Salami reportedly refused to comply and resorted to issuing threats and abusive remarks towards the Ministry’s officials, including the Permanent Secretary.
The Federal Government reiterated that the primary role of university councils is to ensure the smooth operation of academic activities, strictly adhering to the laws establishing each institution.
Tinubu warned university councils against engaging in actions that could destabilize their institutions, as his administration remains committed to enhancing the nation’s education system.
The Ekiti State Government has reached an agreement with labour leaders in the state, signing a Memorandum of Understanding (MoU) for the payment of the N70,000 minimum wage approved by the Federal Government.
Addressing journalists at a brief ceremony in Ado-Ekiti on Tuesday, the Head of Service (HoS), Dr. Folakemi Olomojobi, announced that the payment would commence immediately.
She lauded Governor Biodun Oyebanji for prioritizing the welfare of workers despite the state’s limited resources.
“This development demonstrates the governor’s commitment to improving the livelihood of our workers,” Dr. Olomojobi stated, highlighting the proactive measures taken by the administration to ensure prompt implementation.
In their remarks, the Trade Union Congress (TUC) Chairman, Comrade Sola Adigun, and the Nigeria Labour Congress (NLC) Chairman, Comrade Olatunde Kolapo, expressed their appreciation to Governor Oyebanji for fulfilling his promises to workers.
They confirmed that the new minimum wage would apply to all cadres, including employees in ministries, parastatals, agencies, and pensioners.
The Chairman of the Joint Negotiating Committee (JNC), Comrade Femi Ajoloko, described the implementation as a fair and commendable adjustment.
“This decision reflects the governor’s magnanimity and his dedication to fostering a productive workforce in Ekiti State,” he said.
