“…The low yield in many sub-Saharan African countries is possibly a direct result of the low use of improved varieties, highly variable rainfall, and the low use of fertilizers (Dembele et al, 2021). Although this low yield is a challenge for food security in these countries, it represents an opportunity to attain higher sorghum production from the same cultivated areas by using a combination of fertilizers, new cultivars, and improved agronomic practices (Sanders et al, 2019).…”

Some cereal crops can withstand harsh growing conditions, and, hence, can be considered an important line of defense against food shortage under climate change. Sorghum (Sorghum bicolor (L.) Monech) is the main food crop for millions of people, especially in sub-Saharan Africa and South Asia. This crop performs well under input constraints (e.g., limited water) and exhibits high resilience to adverse climate conditions (e.g., high temperature, drought, and waterlogging), making it a star crop for combating hunger under climate change. However, sorghum and other similar crops are not tolerant in absolute terms. Climate change could push the growing conditions of these crops beyond the limits they can tolerate, jeopardizing the food security of millions of people around the world. In this research, we analyzed the current status of sorghum production, trends, and factors controlling sorghum yield using empirical approaches. Especially in sub-Saharan Africa, this crop is cultivated widely under unfavorable climate conditions and sub-optimal input levels. Our findings raise multiple concerns as well as highlight opportunities for the sustainability of sorghum cultivation in a future with climate change. Sorghum yield seems to increase persistently despite global warming due to an improved inputs approach, offering hope that similar adaptation approaches can be fruitful, especially in sub-Saharan Africa. A combination of interventions including adequate use of fertilizers and technology adoption (e.g., tolerant cultivars), efficient management (e.g. improved irrigation), and better agronomic practices, is the key to boosting sorghum yield and ensuring the sustainability of this important crop under a warmer climate.

“…The Northeast African region also includes CWR of staple food crops like sorghum S. bicolor (L.) Moench and teff Eragrostis tef (Zuccagni) Trotter that provide food for millions. Sorghum is the fifth largest grain crop in terms of world production, and 46% of the world's consumption occurs in sub‐Saharan Africa, both as food for people and feed for animals (Raubach et al., 2021; Sanders et al., 2019). In Sudan, sorghum is the main staple crop, accounting for about 80% of the total cereal production.…”

Crop wild relatives (CWR) are an important source of genetic diversity useful for crop improvement. This study was conducted to create both a checklist and priority inventory of CWR in Northeast Africa. A partial CWR regional checklist was obtained by combining the floras of Djibouti, Ethiopia and Eritrea, Somalia, South Sudan, and Sudan for priority crop genera. It includes 1,020 taxa belonging to 39 families and 130 genera, about 80% of these taxa are native. The families with the highest number of CWR were the Poaceae (334) and Fabaceae (202). The checklist was then prioritized based on the social and economic value of the related crops using the Food and Agriculture Organization Corporate Statistical Database (FAOSTAT), and the potential use of CWR for crop improvement using the crop gene pool or taxon group concepts. These criteria were applied to the checklist via a serial method to generate a prioritized inventory of 97 CWR taxa belonging to 19 families and 44 genera. Forty‐three percent of these taxa occur in more than two countries and additionally 32% in Eritrea and Ethiopia, 18% in Sudan and South Sudan and 7% in Somalia. For crop improvement, 20% of the taxa have confirmed uses, 23% have recorded potential uses, and 28% have both confirmed and potential uses. This prioritized list includes important CWR taxa related to regionally important food crops such as sorghum and teff, as well as providing a foundation for further conservation studies by conservationists and breeders in this region and worldwide.This article is protected by copyright.

“…In certain regions of the world, sorghum is used mostly for human food. In the USA, sorghum is primarily used as an animal feed ingredient and as a feedstock for biofuel production [ 1 ]. In addition, due to the health promoting nature of the crop and its consumer valued qualities, such as being gluten free and a non-GMO product, sorghum’s use as human food is also increasing.…”

Near infrared (NIR) spectroscopy is widely used for evaluating quality traits of cereal grains. For evaluating protein content of intact sorghum grains, parallel NIR calibrations were developed using an established benchtop instrumentation (Perten DA-7250) as a baseline to test the efficacy of an adaptive handheld instrument (VIAVI MicroNIR OnSite-W). Spectra were collected from 59 grain samples using both instruments at the same time. Cross-validated calibration models were validated with 33 test samples. The selected calibration model for DA-7250 with a coefficient of determination (R2) = 0.98 and a root mean square error of cross validation (RMSECV) = 0.41% predicted the protein content of a test set with R2 = 0.94, root mean square error of prediction (RMSEP) = 0.52% with a ratio of performance to deviation (RPD) of 4.13. The selected model for the MicroNIR with R2 = 0.95 and RMSECV = 0.62% predicted the protein content of the test set with R2 = 0.87, RMSEP = 0.76% with an RPD of 2.74. In comparison, the performance of the DA-7250 was better than the MicroNIR, however, the performance of the MicroNIR was also acceptable for screening intact sorghum grain protein levels. Therefore, the MicroNIR instrument may be used as a potential tool for screening sorghum samples where benchtop instruments are not appropriate such as for screening samples in the field or as a less expensive option compared with benchtop instruments.
