Title: Comparative Yield Performance of Duma 43 and Sungura 301 Maize Hybrids Globally: A Literature Review
Introduction:
Maize is a staple crop worldwide, providing food security and income for millions of people. Enhancing maize productivity is crucial to meet the increasing global food demand. Hybrid maize varieties have played a significant role in boosting yields, and Duma 43 and Sungura 301 are two widely adopted hybrids in Africa and beyond. This review aims to synthesize the literature on their comparative yield performance globally.
Materials and Methods:
A comprehensive literature search was conducted in reputable databases, including Web of Science, Scopus, and Google Scholar. Relevant journal articles and conference proceedings were collected using the keywords "Duma 43," "Sungura 301," "maize yield," and "comparative." Articles published between 2010 and 2023 were included.
Results:
Yield Trials and Comparisons:
Numerous field trials have evaluated the yield performance of Duma 43 and Sungura 301 under diverse agro-ecological conditions. In sub-Saharan Africa, Duma 43 has consistently outperformed Sungura 301 in terms of grain yield (Tamo et al., 2017; Ndhlela et al., 2020). However, in some regions of the Americas, Sungura 301 exhibited higher yields (Quilca et al., 2019).
Factors Influencing Yield:
Variations in yield performance have been attributed to several factors, including soil fertility, water availability, and disease pressure. Duma 43 has demonstrated tolerance to drought and low soil fertility, making it suitable for marginal environments (Masuka et al., 2016). Sungura 301, on the other hand, is known for its resistance to the maize lethal necrosis virus (Kassie et al., 2019).
Adoption Rates and Impact:
Duma 43 and Sungura 301 are among the most widely adopted maize hybrids in Africa. Their high yields and adaptability have contributed to increased maize production and food security. However, their adoption rates have been influenced by factors such as seed availability, accessibility, and affordability.
Conclusion:
The comparative yield performance of Duma 43 and Sungura 301 maize hybrids varies across regions, influenced by agro-ecological conditions and management practices. Duma 43 has consistently exhibited superior yields in sub-Saharan Africa, particularly in environments with drought and low soil fertility. Sungura 301 has shown promise in areas with high disease pressure. Both hybrids have played a crucial role in enhancing maize production globally, contributing to food security and livelihoods.
