The success of the trials  and the eventual adoption of this new yam growing technique will substantially reduce the volume of the root crop used as seed  and, in effect, increase the amount of yam available to farmers for sale or for consumption.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe technology will save farmers the cost  and difficulty of acquiring seed yams,\u201d says Joshua Aliyu, a staff with the Niger State Agricultural Development Project, who is working on the trials. \u201cIt would be a rebirth of yam cultivation in our community,\u201d he adds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAside from its economic  and food security benefits, the new yam growing technique also substantially decreases or even eliminates the transmission of diseases (nematodes), a main cause of low yields in yams\u201d, says Dr Hidehiko Kikuno, IITA Yam Physiologist  and leader of the project that developed the technology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The technique makes use of vine cuttings planted in carbonized rice husk (CRH) as growth medium. After rooting  and sprouting, the seedlings are transferred to the field or directly planted into nursery beds with CRH under shade.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kikuno says the abundance  and availability of rice husks\u2014the growth medium \u2013 in rural communities makes the research relevant. \u201cThis enables farmers to easily  and cheaply propagate yam through vine cuttings by themselves,\u201d he adds. In sub-Saharan Africa, the cost of planting materials (seed yams) account for about 50 per cent of the total production cost.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project to develop the technique was funded by the Japanese government, the Sasakawa Africa Association, Tokyo University of Agriculture  and the International Cooperation Center for Agricultural Education, Nagoya University, Japan. Partners in the research included the Tokyo University of Agriculture; National Root Crops Research Institute &#8211; Umudike, Nigeria; Crop Research Institute, Kumashi, Ghana  and the Institute of Agricultural Research for Development, Cameroon.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">###<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pour plus d'informations, veuillez contacter :<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hidehiko Kikuno, <a>h.kikuno@cgiar.org<\/a><br>Yam Physiologist<br>IITA-Ibadan<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jeffrey T.
