Neglected legumes like Bambara groundnut (Vigna subterranea (L.) Verdc.) can serve as a high nutrient pulse and also as food supplements. However, despite the fact that Bambara groundnut contains these beneficial bioactive compounds, it also has some compounds, which on the other hand do exists as acute poisons and as contaminants in food, thus implying risks of adverse effects in animals and man. However, the ingested dosage of bioactive plant compounds is often a determinant for a decision as to whether the effect will be beneficial or adverse. Here, the work quantified and reported certain plant bioactive compounds and anti – nutrients in Bambara groundnut (Vigna subterranea (L.) Verdc.). The results of some bioactive compounds analysed...

The irvingia trees occur naturally on farms in Cameroon [1], but are planted in home gardens in Nigeria (Ukafor 2001). A study by Ayuk et al. [2] in the humid lowlands of Cameroon indicates that most farmers maintain mature bush mango trees that are already growing on their land and also transplant wild seedlings onto their farm or raise new seedlings. Franzel et al. [3] carried out a priority setting exercise in Nigeria, Cameroon and Ghana, and found out that Irvingia gabonensis is the most preferred indigenous tree species in the humid lowlands of Nigeria and Cameroon. Eighty-six percent of respondents mentioned the species in both countries, with an average preference score of 7.8 in Nigeria and 6.0 in Cameroon. In a study of under-exploited tree crops, Moss concluded that I. gabonensis, also called bush mango, ...

Verdc) among the 1973 maintained in the global repository at the International Institute of Tropical Agriculture (IITA), Ibadan, genebank were selected for this study. Two to three seeds of each accession were planted during the 2014 / 2015 planting season at IITA, Ibadan, Nigeria. Seedlings were thinned to a single plant prior to flowering. Thirty - seven (37) agro-morphological parameters, representing 28 quantitative and 9 qualitative traits were recorded on each plant (IPGRI, 2000). The data were subjected to analysis using the statistics application system (SAS) software, version 9.3, both to depict correlation among parameters and eigen values with principal component on scree plot and dendrogram construction. The results revealed lines (e.g TVSu – 293, TVSu – 395, TVSu – 1243) that had high yield potentials. Also, TVSu -397 and TVSu – 1168 had the highest number of leaves while TVSu – 520 and TVSu – 1...

Verdc.) of African origin. With a view to predict the perception or sensory evaluation of its products; commercial purchase of cream coloured Bambara groundnut (BG) from Bodija market, Oyo – state, Nigeria was made into two main products (cooked Bambara groundnut beans and cooked Bambara groundnut paste 'okpa') and served to fifteen (15) respondents each; representing employees of the National Centre for Genetic Resources and Biotechnology (NACGRAB), Ibadan, Nigeria, serving as taste panelists / perceptionists for these products. The results obtained showed that 58.32% of the respondents preferred the look of the beans as appealing to consume while the okpa appeals to 64.27% of them. Also, the product smell and taste were scored 49.91% and 58.22 % respectively for the cooked Bambara beans, as against those for okpa, which were 85.71% and 71.42% respectively, as attested by the respondents. The overall product acceptability was scored at 62.84% of the respondents for desirability for the consumption of cooked Bambara beans, while 71.42% of them scored the same criteria for the okpa food product. The result of this evaluation indicated that developing countries, like Nigeria can tap into the immense acceptability of the Bambara groundnut food products, with the aim of improving on its sustenable utilisation and consumption towards reducing hunger, malnutrition and enhance food security in a developing country like Nigeria.
