“…Farmers' usual practice is to set aside small-sized tubers of 250 g to 1000 g from the food-yam crop as seed for the next crop, and as much as 30% of the harvest is reserved for planting next year's crop on a farm of similar size to that of the previous year. Thus, seed yams are not only scarce because they compete with food, but are also expensive (Ironkwe 2005), accounting sometimes for as much as 63% of the total variable cost of yam production (Ogbonna, Anyaegbunam, and Asumugha 2011).…”

Yam (Dioscorea rotundata Poir.) is a major staple and cash crop for millions of households in West Africa, where about 93% of the world crop is produced. The tuber serves as food and seed. Depending on the size, seed tubers are often cut into setts, minisetts, or planted whole. An experiment was conducted to investigate the effects of using whole tubers versus minisetts to produce seed yams. Six treatments constituted combinations of whole tubers and minisetts, and three tuber-size classes, viz., 30-59 g, 60-89 g, and 90-120 g (averaged and referred to as 45 g, 75 g, and 105 g, respectively). The experiment was conducted as a randomized complete block design with three replications. Results showed that plants from whole tubers emerged from the soil faster and yielded 48% more than those from minisetts. The mean yield of 105 g minisetts (18.3 t/ha) was statistically similar to that of 45 g whole seed (17.9 t/ha). Using 45 g whole seed would save about 2 t/ha of the harvested crop for use as food instead of seed. So, planting small whole tubers is more profitable than minisetts and is recommended to yam growers.

“…Availability and cost of seed yam have been identified as a major limiting factor in the expansion of yam cultivation. Seed yams are not only expensive but also scarce (Ironkwe, 2005) accounting sometimes for as much as 63% of total variable cost of yam production and also bulky to transport (Manyong, 2000). Scarcity of seed tubers often results in unplanted mounds in farmers' fields and some farmers also keep a reserve batch of seed yams (up to a third of the quantity planted) for replacement of seeds that do not germinate (Aighewi, Akoroda, & Asiedu, 2002).…”

<p>A study was conducted to develop a vine multiplication package for generation of seed yam. The parameters assessed for the package were rooting media of the vine cuttings, yam variety and nutrient supplementation to the mother plant to generate minitubers. Nine varieties of yams were planted in 4 media types (soil, soil + sawdust, soil + carbonized rice husk and cocopeat) and 2 levels of nutrient supplementation (no supplementation and supplementation) using RCBD with 3 replications. The study was conducted over 2-year period. Boosting the nutrient status of the mother plant before excising the vines proved to enhance establishment and subsequently the yield of the vine cuttings. Incorporation of biochar in the planting media also enhanced establishment of the vine cuttings and subsequent yields. Success of the vine multiplication techniques also proved to be variety dependent. An in vivo vine multiplication package has been developed for yam seed generation.</p>

“…In Nigeria, fish production is from both internal and external sources. Of the internal sources, aquaculture is the second most important after artisanal fisheries and supplied between 5-13.5% of total domestic fish production between 2000and 2007(Federal Development of Fisheries (FDF), 2007. Aquaculture or fish farming has the potential of revising the trend of fish importation.…”
