“…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. In a T A B L E 2 (Continued) multi-site-year trial, Serba et al (2020) showed that DP grain yield averaged 1900 kg ha −1 and 4600 kg ha −1 fodder. Dual-purpose millet varieties can be grown as a rainy season crop under rainfed conditions in SSA, in monocropping or intercropped or mixed cropping systems but also in rotation with legumes such as pigeon pea (Cajanus cajan), groundnut, cowpea, mung bean (Vigna radiata), mucuna (Mucuna sp.…”

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.

Pearl millet [Pennisetum glaucum (L.) R.Br.] is an essential subsistence cereal for food security in dryland farming systems of the semiarid tropics (e.g., in sub‐Saharan Africa) and has improved tolerance to drought, heat, and salinity stress compared to other domesticated cereals. Assessing the variation on phenology is critical toward devising effective adaptative management strategies for crop adaptation to current and future climate change. In this context, pearl millet presents a vast genetic diversity, exhibiting sensitivity to temperature and photoperiod. Hence, this study aims to describe the genotypic variability in the phenological responses of pearl millet to temperature and photoperiod, particularly affecting leaf number with implications on the overall total time to flowering. The dataset encompassed 21 publications from seven countries, with experiments conducted from 1965 to 2023, including three field studies from the United States. Broad variability has been reported for phyllochron values ranging from 45 to 111°Cd leaf−1, with a mean value of 67°Cd leaf−1. Thermal time to panicle initiation ranged from 340 to 594°C, but no response to photoperiod duration was found due to the nature of dataset. Maximum number of leaves per shoot ranged from 11 to 25, showing response (1.55–2.15 leaf h−1) to photoperiod due to variations in thermal time to flowering (from 875 to 1346°Cd). Thermal time to flowering increased ca. 323°Cd h−1 under day durations longer than 13.3 h, below which basic vegetative phase duration was close to 1033°Cd. Based on the Agricultural Production Systems sIMulator simulations, different combinations of the above responses (in silico cultivars) generated a great range of times to flowering (44–120 days) for locations in Senegal, Brazil, India, and United States. The findings of this study can help breeders to explore the phenological genetic variability of pearl millet and provide inputs for crop growth models to evaluate future in silico scenarios.
