Taro production in Ghana bounces back thanks to research

Few years ago, the taro industry collapsed entirely in Ghana but researchers of the Crop Research Institute of the Council for Scientific and Industrial Research (CSIR) have succeeded in reviving it by developing new taro varieties that meet the industry’s current challenges.

Those are four new varieties that offer high yields and are incredibly resistant to taro leaf blight —scientifically known as Phytophthora colocasia.

This is a highly infectious disease responsible for the extinction of the crop.

The West Africa Agricultural Productivity Programme (WAAPP) supported the institute to find solutions to the collapse of the taro industry in Ghana,” says Dr. Ernest Baafi, cocoyam and taro breeder at the Crop Research Institute of CSIR.

In 2017, after rigorous testing, Ghana’s National Variety Release Committee recommended four taro varieties for government approval.

After this step, the four varieties finally had the country’s Seed Board’s approval to be made available to farmers.

The varieties are currently at the stage of dissemination throughout the country.

For that purpose, the CSIR is working in collaboration with government authorities, including the Department of Agriculture to make sure these variety

“We have set up a multiplication field in each municipality, and these fields will help serve the farmers in the municipality,” explains Dr. Baafi.

Farmers have welcomed the varieties and, in some municipalities, the impatience of having them is growing.

“I can’t wait to get the new taro seeds to resume my taro cultivation,” says Mrs. Akosua-Sera, who is also in charge of the seed multiplication field of her municipality located in the suburb of Kumasi.

“I am happy that these new varieties will come and have a higher yield. This will allow me to have good income-generating activity and to take care of my family,” she says.

Indeed, the new taro varieties offer a yield that varies between 12 and 25 tons per hectare, while the old one hardly offered five tons per hectare and suffered, helplessly, the assaults of the taro leaf blight.

“We can say today that the taro industry is reviving in Ghana through the WAAPP,” says Dr. Baafi.

The new varieties developed by the CSIR in Ghana can be eaten boiled or cooked; others can be used to make the pastry, chips, etc.

The WAAPP is an initiative of the Economic Community of West African States. It has been funded by the World Bank. Under the technical coordination of CORAF, the initiative started in 2008 and ended in December 2019.
