Bambara groundnut (Vigna subterranea L.) is a neglected African crop legume with potential to play a significant role as a staple and industrial crop in sub-Saharan Africa. The crop can compete with Phaseolus vulgaris and Glycine max under harsh condition associated with climate change. However, there are some challenges associated with successful production of bambara groundnut, such as poor crop establishment due to physical seed dormancy. This study was conducted to investigate the effect of scarification on overcoming seed dormancy in bambara groundnut. Bambara groundnut landrace seeds were characterized by seed coat colour (cream, light brown and brown) in order to determine the effects of mechanical (sand paper) and chemical (sulphuric acid) seed scarification on germination and emergence. A completely randomized design with three replications was used. Thousand grain mass (TGM), mean germination time (MGT), germination vigour index (GVI), seedling root to shoot ratio, seedling dry mass and field emergence were determined. Thousand grain mass increased with the decrease in seed coat colour pigmentation. Brown seeds had the highest final germination and field emergence, and cream seeds had the least. Imposing chemical or mechanical scarification improved germination as compared to no scarification. However, seedling establishment was vigorous in seeds that were not scarified. Seed quality in bambara groundnut is highly influenced by scarification and seed coat colour. The practical implications of the study are that producers can use scarification to improve bambara groundnut germination, however further research through seed enhancements is still needed for seedling establishment under field conditions.

“…Several studies in South Africa have alluded to the advantages observed in NUS grown under resource limitations as being related to good ecophysiological responses [1,43,66]. For instance, Mabhaudhi [65] stated that stable yields observed in bambara groundnut grown in different water regimes were associated with reduction in canopy size and maintenance of high stomatal conductance. Cowpea was observed to shed leaves and assume a state of growth arrest under prolonged low water availability and resume growth when soil water availability improves [68].…”

“…Although cultivating low input crops like NUS in marginal lands presents huge advantages, parallel disadvantages may have elevated the promotion of major crop species within smallholder farming systems. Mabhaudhi [65] argued that the poor establishment of bambara groundnut may partly explain why farmers have moved away from cultivating it. To exploit the full potential of NUS, and promote their adoption into existing cropping systems, aspects of crop and soil management strategies need to be formulated.…”

Underutilised crops represent an important component of agro-biodiversity with potential to contribute to climate change adaptation, food security and sovereignty in poor rural areas. However, despite emerging research interest, they continue to occupy the peripheries of mainstream agriculture. There is a need to consolidate the gains made and propose a coherent strategy for translating underutilised crops into mainstream agriculture. The status of underutilised crops in South Africa (past, present and on-going research) was reviewed with a view to identifying existing gaps, opportunities and challenges for developing future research capacity. The review confirmed that several underutilised crops are drought tolerant, adapted to low levels of water use and thus suitable for cultivation in most marginal production areas typical of semi-arid and arid cropping systems. In addition, several are nutrient dense and could be used to improve dietary diversity among poor rural people. These characteristics make them ideal for inclusion in climate change adaptation and promotion of food sovereignty. There is need for a paradigm shift away from practices that have promoted a few major crops to an agro-ecology based land use classification system that recognises diversity and strengthens food networks. There is a need to identify those underutilised crops that show the greatest potential for success and can be fitted into semi-arid and arid cropping systems and prioritise them for future research, development and innovation.
