New seed tuber systems from mini-sett, mini-tubers, and vine cuttings have been developed for yam productionto supplant the traditional systems which have been proven inefficient and costly. The new techniques provide producers in tropical countries with the opportunity to minimise production costs reducing seed tuber price and promoting great availability for seed. A discounted cash flow budget with a whole farm perspective was used to analyse the economic performance and risk implications, of a hectare investment in the new seed tuber system over time for a representative farm. Data based on realistic process costs and review of past reported studies were employed to reflect the relative economic worthiness and opportunity cost of investment and operating capital of seed tuber systems in Nigeria. From the NPV and BCR analyses, the new seed tuber systems were more viable than current traditional seed tuber systems through milking of live immature plants. This raises the need to identify which among the new techniques could be the most profitable and recommendable.Therefore, understanding the economics of seed tuber systems would not only help a large section of stakeholders at local, regional and national levels but also prove beneficial to policymakers, funding agencies and non-government organizations embarking upon the yam projects and programmes.
