“…Major constraints responsible for the slow rate of increase in yam productivity especially in West Africa have been identified to include non-availability, high cost and poor quality of planting materials, pests and diseases, as well as declining soil fertility (Tetteh and Saakwa, 1994). Limitation in the supply of seed yam results from the fact that most farmers depend largely on their own production with only a small proportion being obtained from the market (Asumugha et al ., 2007). The absence of specialised seed producers is an indication that seed yam found in markets is often the leftovers after farmers have planted or reserved enough quantities to plant their own fields.…”

The influence of minisett size and time of planting on the yield of seed yam (Dioscorea Rotundata)

In traditional yam (Dioscorea spp.) production systems in West Africa, finding sole seed yam producers is rare and up to 30% of harvested tubers from the ware tuber crop is reserved to plant an equivalent area of the harvested crop during the next season. Many farmers typically must make a trade-off between food and seed in the use of available tubers. A study was carried out using a factorial experiment in a randomised complete block design to investigate the influence of planting different minisett sizes at different planting periods on the yield of seed yam with the aim of improving the availability of this expensive input and saving more ware tubers for food or sale. Results showed that by doubling or tripling the minisett size from 30 to 60 or 90 g, yields of seed yam increased by 61.1 and 103.3%, respectively. The 90 g minisetts had the highest values for all traits studied but had the least sett multiplication ratio. The early planted crop yielded 137% more than the late-planted crop. Significant interactions between minisett size, planting period and season were found. In 2016, although the highest yield of seed tubers was from early planted 90 g minisetts (35.6 t ha−1), the yield of early planted 30 g minisetts (23.8 t ha−1) was similar to those of 60 g planted mid-season (28.7 t ha−1) and 90 g planted late (20.0 t ha−1). To produce a high proportion of seed size tubers with less planting material, early planting of 30 g minisetts is recommended. Such practice will enhance seed tuber availability and food security by saving 1–2 t ha−1 of tubers that would have been used as seed instead of food.

A developed ginger harvester was studied for its performance during operation using response surface methodology. Some of its parameters like speeds of operation, digger lengths and spacing, were varied to determine their effects on the Material Efficiency of the machine. Three levels of speeds (4,8,12km/hr), three levels of digger lengths (25,30,35cm) and three levels of digger spacing (4,6,8cm) were investigated as they affected the Material Efficiency of the machine. Results showed that the linear effects of speed, the quadratic effects of speed, the quadratic effects of digger lengths and the interactions of speeds and digger lengths were significant to the Material Efficiency of the ginger harvester at 5% probability (P≤ 0.05). These effects alone accounted for about 94.14% of the variations in the Material Efficiency of the machine. The response surface curve showed that the material efficiency increased with speed and digger spacing, but decreased with digger lengths. The highest overall Material Efficiency was obtained when the digger lengths were 25cm and the digger spacing was 8cm.

POSSIBLE THERAPEUTIC EFFECTS OF Dioscorea alata (WATER YAM) EXTRACT ON TRAMADOL-TREATED WISTAR ALBINO RATS' GASTROINTESTINAL SYSTEM.

It has long been recognised that Dioscorea alata (water yam), provides therapeutic benefits. The commonly used analgesic tramadol has been linked to negative effects on the gastrointestinal tract. The researchers looked at how Dioscorea alata (water yam) extract might help the digestive systems of albino rats that had been given tramadol beforehand. A controlled experimental setup was used with twenty-five albino rats split up into five groups (control, negative, positive, and counter groups). Histological investigations assessed the structural and functional changes to the gastrointestinal tissues. Cell damage, oxidative stress, and tissue inflammation were among the parameters that were assessed. The statistical programme for social sciences, or SPSS version 20, was used to analyse the data that was produced. Group 3 rats' body and organ (stomach) weights were significantly lower than those of Group 1. This investigation showed that tramadol inflamed the gastrointestinal tracts of the rats in group 3. On the other hand, it was shown that Dioscorea alata helped to reduce some of these inflammations and changes in tissue architecture. The gastro-intestinal tract of rats in group 3 that were only given Dioscorea alata had some mild inflammatory cells. This study suggests that the extract from Dioscorea alata may lessen tramadol-induced gastrointestinal tissue damage in albino Wistar rats. It is recommended that human subjects be used for further research in order to clarify the underlying processes of these effects, evaluate dose concerns, and analyse the long-term effects of such treatment.
