Yam Programme

Ghana is the leading exporter of yams in the world. Tuber size and variety are key criteria for premium price on the export market.  Premium price for Pona is obtained from a 20 kg box of yam with 10-12 tubers and in extreme cases 14 tubers; with corresponding average tuber sizes ranging between 1.4 -2kg.  A 25 kg box of other white yam varieties should contain 14 -16 tubers (1.8 and 1.6 kg/tuber), mostly within the medium class. Amongst the key technologies being disseminated include the Yam Vine Technology. The technology solves a huge challenge with the conventional means of multiplying yam (1:4-6), which is low compared to the minisett technique, which yields 1:40.  This is far below cereals and makes the expansion and dissemination of new varieties very slow and difficult.  Activities under the seed system have the main objective to develop and disseminate effective and efficient seed multiplication techniques. Specifically, it has evaluated and is now promoting a robust, cost effective, rapid propagation technology for high multiplication ratio of breeder and foundation seed yam.  It also aims at enhancing the water use efficiency in seed yam production.
