  • Can cropgro-soybean model help improve production of soybean in Ethiopia?
  • In conclusion, the CROPGRO-soybean model can serve as a useful tool for quantifying the potential yield, yield gaps and the possible causes of the yield losses, which guides designing suitable strategies for better production of soybean in Ethiopia.
  • Where do Ethiopian farmers grow soybeans?
  • In the Jimma zone, part of southwest Ethiopia, where rainfed agriculture is common, farmers produce soybean under low input and poor crop management conditions.
  • Why is soybean important in Ethiopia?
  • In Ethiopia, soybean is an important legume, dominantly cultivated by smallholder farmers in the northwest, south, and southwest regions mainly for domestic consumption, income generation, and maize-soybean crop rotation (Abera et al. 2019; CSA 2021; Getachew et al. 2017 ).
  • Is anhydrous production of biodiesel from soybean oil and methanol an original work?
  • We warrant that the article Anhydrous Production of Biodiesel from Soybean Oil and Methanol, Catalyzed by Calcium Oxide in a Recycle Reactor submited to South African Journal of Chemical Engineering is the Authors' original work. We warrant that the article has not received prior publication and is not under consideration for publication elsewhere.
  • Is soil fertility a future challenge to Ethiopia's agriculture?
  • Sustaining agricultural production; while maintaining soil fertility is a future challenge to Ethiopia’s agriculture that must be overcomed by increasing productivity and yield (Kassie et al. 2008; Yigezu 2021) on existing land to supply adequate and nutritious food, feed, and other products.
  • Are simulated phenological stages and growth of soybeans in good agreement?
  • Model evaluation results revealed that the simulated phenological stages, growth, and yield of the two soybean varieties were in good agreement with the corresponding measured values. The evaluated model was used to quantify potential yield, water-limited yield, and yield gaps.
