“…Several studies on millet in Senegal found that higher plant densities resulted in higher yields (Bastos et al, 2022;Faye et al, 2023;Pilloni et al, 2022;Vieira Junior et al, 2023), which is similarly found in this paper. Additional evidence for the potential benefits of delaying the planting date has on millet yield in Senegal can be seen in other studies, thus confirming our results (Araya et al, 2022;Vieira Junior et al, 2023).…”

In Senegal, agriculture is an important sector underpinning the socioeconomic fabric of the populace. Notably, the agricultural production in this region exhibits heightened sensitivity to climatic perturbations, particularly droughts and heat waves. This study aims to determine the resilience of different agronomic interventions for farmers practicing mixed farming that produce both crops (i.e., groundnut (Arachis hypogaea L.) and pearl millet (Pennisetum glaucum (L.) R. Br.)) and raise animals in the Groundnut Basin in Senegal, which holds historical and socioeconomic significance. To understand the current situation regarding demographics, economics, consumption behavior, and farm operations for smallholder farmers, data were comprehensively collected from government and nongovernment organizations (NGO) reports, scientific papers, organization databases, and surveys. Additionally, the Agricultural Production Systems sIMulator (APSIM) was used to understand how combinations of three planting dates, three plant densities, and six urea nitrogen (N) fertilizer rates affected the yield of pearl millet, which were used as the alternative scenarios to the baseline in the farm modeling and analyses. All the collected and generated data were used as inputs into the Farm Simulation Model (FARMSIM) to generate economic, nutritional, and risk data associated with mixed farming systems. The generated data were then used to determine the resilience of the alternative scenarios against the baseline. Initially, a multi‐objective optimization was employed to meet nutritional needs while maintaining a healthy diet at the lowest cost. Then, the scenarios that met the population's nutritional requirements were evaluated based on four economic indicators: net cash farm income (NCFI), ending cash reserves (EC), net present value (NPV), and internal rate of return (IRR). Lastly, those that passed the economic feasibility test were ranked based on risk criteria certainty equivalent (CE) and risk premium (RP). The analyses found N fertilizer rates of 0, 20, and 100 kg N ha−1 were generally economically not feasible. Additionally, medium (early‐July to late‐August) and late (late‐July to mid‐September) planting dates generally performed better than early (early‐June to late‐July) planting dates, while plant densities of 3.3 and 6.6 pL m−2 performed better than 1.1. The robust resilience approach introduced in this study is easily transferable to other regions.

“…The fodder yield ranged from 250 kg ha −1 (Siébou et al, 2019) to 4100 kg ha −1 (Watanabe et al, 2019). A recent Genotype × Environment research conducted in Senegal (Bastos et al, 2022) observed an average grain yield ranging from 928 to 2334 kg ha −1 for Souna 3 (TV) and 1039 to 2616 kg ha −1 for Thialack 2 (DP variety) across different site‐years (Figure 5). Kanfany et al (2018) reported an average grain of 1268 kg ha −1 for Souna 3 (TV variety) and 1694 kg ha −1 Thialack 2 (DP variety) in Senegal.…”

“…Although nutrient requirements could be different between traditional and DP varieties of millet, the recommended 150 kg h −1 NPK (15‐15‐15) as a single rate for TV is used for DP varieties across SSA. Nevertheless, some recent studies (e.g., Bastos et al, 2022; Faye et al, 2023) have shown that DP varieties perform well with 91‐32‐24 NPK.…”

“…For example, Faye et al (2023) showed that millet DP varieties such as Thialack 2, SL28, and SL169 have twice the nitrogen use efficiency of the traditional variety, Souna 3. In a Genotype × Management × Environment trial, Bastos et al (2022) showed that for the same amounts of fertilizer, DP variety produced more grain and biomass than TV in different environments in Senegal.…”

Addressing the challenge of food and nutrition insecurity in Sub‐Saharan Africa (SSA) will require innovative agriculture production systems that support multiple objectives. In recent years, several high‐yielding, and nutrient‐dense varieties of cowpea (Vigna unguiculata (L.) Walp), pearl millet (Pennisetum glaucum (L.) R. Br.), and sorghum (Sorghum bicolor (L.) Moench) have been developed purposely as dual‐purpose (DP) varieties in SSA to meet human nutrition and livestock feed needs. This review synthesized published data on DP varieties from cowpea, pearl millet, and sorghum. Findings showed that DP crops and varieties were largely grown by smallholder farmers in a variety of soil and climatic conditions with production systems characterized by large gaps between attainable and actual crop yields which varied significantly among regions. While the grain and fodder yield of traditional varieties (TV) of cowpea averaged 700 kg ha−1 and 860 kg ha−1, respectively, the reported grain yield of DP varieties was 1100 kg ha−1 and 2150 kg ha−1 for fodder. The average grain yield of TV millet varieties was 750 kg ha−1 and 2500 kg ha−1 for fodder. Similarly, average grain yield for DP millet varieties was 2000 kg ha−1 and 4200 kg ha−1 fodder. Dual‐purpose sorghum varieties yielded greater grain (>3000 kg ha−1) and fodder (3500 kg ha−1) compared to TV. Little data were obtained on the nutritive qualities of cowpea, millet, and sorghum DP varieties. However, DP millet varieties were reported to be more digestible than TV varieties. Furthermore, adoption of DP varieties improves fertilizer use efficiency, profitability, environmental sustainability, and resilience of the whole farm system compared to TV. Considering fertilizer's high prices, availability, and quality in semi‐arid countries in addition to farmer poverty level, economic evaluation and environmental impact assessment are critical before wide dissemination.
