“… Factors influencing Crop References Lack of adequate finances to invest in the development of new varieties can negatively influence the availability of farmer-preferred legume varieties (1). This can also lead to slower varietal development and release – resulting in a limited number of improved legume varieties for smallholder farmers to adopt Bambara nut, chickpea, lentil Agyeman et al ( 2021 ) Lack of timely access to improved legume seed negatively influences adoption rates (7) from the formal seed system – this can be due to inefficient demand estimation mechanisms for formal seed supply Bambara nut, pigeonpea, chickpea, common bean, lentil, climbing bean Agyeman et al ( 2021 ); Asfaw et al ( 2012 ); David et al ( 2002 ); Dessalegn et al ( 2022 ); Mwalongo et al ( 2020 ); Ronner et al ( 2018 ); Shiferaw et al ( 2008 ) Lack of access to information about new varieties has a negative influence on adoption (4) Pigeonpea, chickpea, soybean Asfaw et al ( 2012 ); Dionco-Adetayo et al ( 2002 ); Mahama et al ( 2020 ) Minimal promotion of variety influences adoption negatively (1) Common bean David et al ( 2002 ) Lack of access to other agri-inputs can influence legume seed adoption negatively (2).

As a fundamental pillar of food security in sub-Saharan Africa (SSA), ensuring seed security is critical to empowering farmers in cultivating food and livestock feed, thereby fostering income generation from agricultural outputs. Among the crops cultivated by smallholders, legumes have the potential to deliver multifaceted benefits. Legumes are nutrient-dense and enhance soil health through their nitrogen-fixing qualities. However, in many instances, the development, release, and supply of improved legume varieties are insufficient to meet the needs of smallholder farmers in SSA. Here, we systematically reviewed the literature to (i) identify and categorize existing legume seed systems, (ii) map legume varieties available to smallholders, (iii) identify barriers hindering the adoption of various legume varieties, and (iv) identify potential strategies and opportunities for strengthening legume seed systems in SSA. Our results demonstrate the coexistence of formal and informal seed systems within legume seed supply chains in SSA, each employing unique seed distribution channels. Smallholders, however, are shown to predominantly depend on the informal seed system to source most legume seeds except for commercially available varieties. We also identified a diverse range of legume varieties available to smallholders in the region, with farmers having varying trait preferences based on crop type and gender. Notably, high yield and abiotic stress tolerance were the most preferred traits. The adoption of these varieties, however, is influenced by various factors, including lack of timely access to seeds in adequate quantities from the formal seed system, high seed costs, and limited information on new varieties. The reviewed literature highlighted that utilizing improved legume varieties had a positive effect on smallholders, leading to improved welfare, food security, dietary diversity, and income. We conclude that the effective scaling of legume systems in SSA is contingent upon the presence of supportive policy frameworks and well-established technical support structures.

“…Previous studies showed that productivity was important for farmers (Acheampong et al, 2018;Agyeman et al, 2021), regarding the chili's resistance to pests and diseases, which farmers frequently complain about (Kirana et al, 2021;Rahayu and Febriani, 2021). Farmers prefer resistant chili varieties because they reduce pest and disease infestation and the risk of crop failure (Moekasan et al, 2015;Kusmana et al, 2019;Lubis et al, 2019).…”

The majority of Indonesian farmers plant open pollinated (OP) chili because the seed price is affordable. However, the chili has weaknesses, such as the productivity is lower and the seed is not uniform. Indonesian Vegetables Research Institute (IVegRI) attempts to create high-quality OP chili varieties that farmers could access. The study aimed to identify farmers, traders and households’ preferences for OP chili varieties that IVegRI has released. The study was carried out in Lembang Sub-district, West Java Province, Indonesia, from March to November 2019. A total of 82 respondents, consisting of farmers, traders and households, were asked about their preference for three OP chili varieties, namely Tanjung, Carvi and Ciko. The respondents were selected purposively. Data were analyzed using perceived quality. The results of this study have revealed that production per plant was the most important chili attribute for farmers, while fruit shape and color were the most essential chili attributes for traders and households, as evidenced by the final scores of 4.93, 4.83 and 4.45, respectively. Traders preferred Tanjung chili variety, as indicated by a score of 1.04. Meanwhile, the farmers and households preferred Carvi to Tanjung and Ciko varieties, with a score of 1.05. Farmers' preference for Carvi for all attributes was higher than the average among varieties, especially for production per plant and fruit weight. This implies that Carvi, as the IVegRI OP chili variety, can be disseminated widely to other locations in West Java and other provinces in Indonesia. The findings of this study are expected to provide useful information for a better understanding of factors necessarily considered to further improve IVegRI's OP chili varieties.

“…However, it is cultivated chiefly across Africa, Central and Southern America, and some Asian countries, including Malaysia, Sri Lanka, Indonesia, and Northern Australia. Bambara is an essential crop in Africa's sub-Saharan continent, with a high tolerance to drought [18], and it thrives well in marginal soils [19]. Several investigations on Bambara found it to have high protein and complete food, providing daily nutritional requirements for adult protein, carbohydrates, and fat or oil [20], with nitrogen fixation capability in the land [21].…”

“…The annual production of Bambara groundnut (BGN) was estimated at 330,000 t in 1982, with approximately 50% coming from West Africa. The production is still at the subsistence level, and global production data has been challenging [19]. In the early 2000s, Zimbabwe exported approximately 2000-3000 tons, yearly, and transported predominantly to South Africa [22].…”

“…Zambia is still the most extensive producer compared to Nigeria, Niger, Ghana [18], Burkina Faso, Mali, Cote D'Ivoire, and Chad. However, the major exporters throughout tropical Africa are Burkina Faso, Chad, Mali, Niger, and Senegal [19]. There is little or no work investigating biomass using combined inert gases during pyrolysis, especially on the BGS [10].…”

Energy from biomass is increasingly gaining attention amidst the environmental challenges of coal and fossil fuels. This study investigated the effects of inert gases (N2, CO2, and N2/CO2) on intermediate pyrolysis and product properties from Bambara Groundnut Shells (BGS) (shells from an underutilized crop, which has high nutritional values). N2/CO2 atmosphere roughly represents flue gas. The results showed that the inert gases did not significantly affect the yields of bio-oil, biochar, and syngas. The pH of bio-oil ranged from 5.2–5.8, indicating the minimum presence of acids in bio-oil. The CHNS analysis showed that all bio-oil and biochar had their carbon content within 50.04–60.49 wt.%. The FESEM resulted in a wide range of pore sizes in biochar produced in an N2/CO2 atmosphere. The GC-MS (Gas Chromatography-Mass Spectrometry) analysis revealed the presence of compounds which can be categorized as alkene, acid, benzene derivatives, ketone, phenol derivatives, alcohol, aldehyde, alkyl, and ester. However, the presence of N2/CO2 gas favored alcohol and phenol production significantly.
