“…This implies that the majority of the respondents obtained their seeds from their previous harvest. This is in line with the findings of Ahmad et al (2022), which revealed that the majority of sorghum farmers from northern Nigeria obtain seeds from previous harvests. 2 reveals that the majority (63.3%) of the female respondents prepared land in ridges.…”

The study assessed gender roles in the production of African black beans (akidi) in Southeast Nigeria. Specifically, it addressed the socio-economic characteristics of the farmers, agronomic practices, gender roles, constraints, and strategies for improving the production of African black beans (ABB). A multi-stage sampling procedure was used to select 192 ABB farmers for the study. Data were collected using a semi-structured interview schedule. Data were analysed using percentage and mean statistics. Results revealed that the average age of female and male respondents was about 44 and 41 years, respectively. Men, women and youths played complementary roles in various operations in ABB production. Men (37.5%, 32.8%, 32.8% and 13.5%) and youths (32.8%, 33.9%, 34.9% and 10.9%) dominated heavy labour operations like land clearing, ploughing, harrowing and fertilizer application, respectively, while women (60.4%, 53.1%, 59.9%, 63% and 61.5%) dominated other operations like planting, harvesting, processing, storage and marketing respectively. Therefore, all genders are involved in ABB production in the area. Efforts should be made to target different genders in ABB production. This can be done through the dissemination of improved technologies in the various production operations. This will ensure that roles are not neglected, thereby enhancing the production of African black beans.

“…Breeding efforts have been made to develop and dispatch abiotic stress-tolerant and high-yielding sorghum varieties. However, the developed varieties were not readily adopted by farmers due to a lack of farmer-preferred traits and poor adaptation to local conditions [4,56]. The present study examined the response of African sorghum genetic resources (Supplementary Table S1) under variable environments to select unique germplasm for production and breeding.…”

“…In terms of yield, sorghum is the third most important cereal crop in Africa with 26.3 million metric tonnes after maize (96.6 million metric tonnes) and rice (37.2 million metric tonnes) [2]. The grains are an important food source that is processed into a variety of traditional cuisines such as couscous, porridge, and semi-leavened bread [3,4]. Sorghum is a major component in the flour blend that is used to produce gluten-free flour with a low glycemic index that is rich in iron and zinc, vitamin B6, vitamin B3 (niacin), magnesium, phosphorus, fiber, unsaturated fats, and protein [1,5].…”

“…Drought stress occurring during the critical growth stages of the crop, including pre-and-post anthesis, has a detrimental effect on grain quality [16,19]. Surveys in Ethiopia, Burkina Faso, and Nigeria indicated that severe drought during the pre-and post-flowering growth stage is a major sorghum production constraint [4,13,20]. As a result, concerted breeding efforts are required to develop drought-tolerant cultivars to urgently mitigate the effects of drought stress and improve sorghum production in SSA.…”

Sorghum (Sorghum bicolor (L.) Moench) is the main food staple for millions of people in Sub-Saharan Africa (SSA) and Asia. Sorghum is relatively drought tolerant and cultivated in arid and semi-arid regions under rain-fed production. However, severe drought stress often leads to crop loss and declined productivity. The development and deployment of high-yielding and drought-adapted genotypes is a cost-effective strategy for sustainable sorghum production globally. The objective of this study was to determine drought tolerance and genotype-by-environment interaction (GEI) effects on grain yields of a population of African sorghum genotypes to identify high-yielding and drought-adapted genotypes for direct production and also for use in breeding programs. Two hundred and twenty-five sorghum genotypes were evaluated under non-stressed (NS), pre-anthesis drought stress (PreADS), and post-anthesis drought stress (PoADS) conditions under field and greenhouse environments using a 15 × 15 alpha lattice design in two replicates. The three water regimes and two environments resulted in six testing environments. Data were collected on grain yield and drought tolerance parameters, and additive main effect and multiplicative interaction (AMMI) analysis were computed. The mean grain yield under NS, PreADS, and PoADS were 3.70, 1.76, and 2.58 t/ha, in that order. The best genotypes adapted to non-stressed environments were G09, and G109, whereas G114 and G56 were suitable for non-stressed and stressed conditions. G72 and G75 displayed the best performance in PreADS conditions only, whereas genotypes G210 and G12 were identified as high performers under PoADS only. The AMMI analysis revealed that genotype (G), environment (E), and GEI were significant (p < 0.05), which accounted for 38.7, 44.6, and 16.6% of the total explained variation in grain yield. AMMI 4 was the best-fitting model for grain yield. Based on AMMI 4 and the Best Linear Unbiased Estimates (BLUPs) calculations, genotypes G119 and G127 with a grain yield of 5.6 t/ha and 6.3 t/ha were selected as being suitable for non-stressed conditions. Genotypes G8 and G71 with BLUPs of 2.5 t/ha and 2.6 t/ha were best-suited for pre-anthesis drought stress conditions, whereas genotypes G115 and G120 with BLUPs of 4.2 t/ha and 4.3 t/ha are recommended for post-anthesis drought-prone environments, respectively. The identified sorghum genotypes are recommended for production in dry agro-ecologies of sub-Saharan Africa characterized by pre-and-post anthesis drought stress. In addition, the identified genotypes are valuable genetic resources to develop novel drought-tolerance material.

“…From the study conducted at Ilora, Oyo State, southwest Nigeria, the identification of high yielding sorghum is an indication that sorghum has enormous potential to thrive well in the southwest of Nigeria: a non-traditional sorghum growing region, which according to Gourichon [ 46 ], accounts for only one percent of the total national output of sorghum production in Nigeria. The low production of sorghum in the southwest of Nigeria has an enormous impact on food security because in traditional sorghum growing regions in Nigeria, such as north-west Nigeria, there has been a drastic decline in the cultivation and production of staple crops such as sorghum, cassava, among others, leading to severe hunger and starvation due to the heavy impact of climate change, drought stress and the armed conflict, which resulted in continuous missed harvest seasons, reduced access to farmlands destruction of agricultural inputs and systems, further worsening food insecurity in this region [ 15 , 47 ].…”
