“…Our results on yield are similar to those reported by Pixley and Bänziger ( 65 ), which showed that under typical growing conditions of eastern and southern Africa, elite hybrids produced 18% more grain than elite POVs in the first generation, but that in the second generation (recycled seeds), OPVs yielded 32% more than hybrids. The results on mineral composition corroborate another finding ( 26 ), which demonstrated that the chemical composition, bioactive compounds, and physical properties (technological quality) of OPV maize were superior than those of hybrids.…”

“…Besides, the current trend in maize development is not solely towards high-yielding hybrids and stress-resistant varieties, but also towards developing nutritionally improved varieties ( 25 ). To achieve this, it is essential to identify maize varieties delivering improved grain quality for human consumption and industrial processing ( 26 ), when cultivated with local and climate-smart farming practises. Therefore, to generate baseline information for the development of more nutritious maize, the nutrient composition of hybrids and open-pollinated varieties (OPVs) of maize landraces needs to be assessed.…”

Maize is a major staple and plays an essential role in food and nutrition security in Sub-Saharan Africa (SSA). Conservation agriculture (CA), a climate-smart agriculture practise based on minimum soil disturbance, crop residue retention, and crop diversification, has been widely advocated but without extensive research on the impact it may have on maize nutrient composition, and food and nutrition security. This study assessed the grain yield, macro- and micronutrient mineral content, and nutrient yield of eight maize varieties grown in Malawi, and how these are affected by CA practises over two seasons. The minerals were analysed by inductively coupled plasma (ICP) coupled to optical emission spectroscopy (OES) and to mass spectroscopy (MS). Grain yield and Se content differed among the varieties, while C, N, Fe, K, Mg, Mn, P, and Zn were similar. The local variety Kanjerenjere showed lowest grain and nutrient yields. The open-pollinated varieties (OPVs) concentrated more minerals than the F1 hybrids, but the latter showed higher yields for both grain and nutrients. Typical consumption of the eight maize varieties could fully meet the protein and Mg dietary reference intake (DRIs) of Malawian children (1–3 years), as well as Mg and Mn needs of adult women (19–50 years), but their contribution to dietary requirements was low for Fe (39–41%) and K (13–21%). The trials showed that CA increased grain yield (1.2- to 1.8-fold) and Se content (1.1- to 1.7-fold), but that it had no effect on C, K, Mg, P, and Zn, and that N (1.1- to 1.2-fold), Mn (1.1- to 1.8-fold), and Fe (1.3- to 3.4-fold) were reduced. The high increase in grain yield under CA treatments resulted in increased yields of protein and Se, no effect on the yields of K, Mg, Mn, P, Zn, and reduced Fe yield. Conservation agriculture could contribute in reducing the risk of Se deficiency in Malawian women and children but exacerbates the risk of Fe deficiency. A combination of strategies will be needed to mitigate some of the foreseen effects of climate change on agriculture, and food and nutrition security, and improve nutrient intake.

“…Comparison of maize hybrids and autochthonous landraces from Eastern Europe (Serbia and Bosnia and Herzegovina) maintained at the Maize Research Institute Zemun Polje gene bank, differing for grain color, physical properties, grain protein fractions, phenolic compounds, carotenoids content and antioxidant capacity resulted in higher values obtained in landraces (67). Autochthonous varieties have better technological grain quality and performed better than hybrids for dry grain milling and snack food production.…”

Traditional Foods From Maize (Zea mays L.) in Europe

et al. 2022

Maize (Zea mays L.) is one of the major crops of the world for feed, food, and industrial uses. It was originated in Central America and introduced into Europe and other continents after Columbus trips at the end of the 15th century. Due to the large adaptability of maize, farmers have originated a wide variability of genetic resources with wide diversity of adaptation, characteristics, and uses. Nowadays, in Europe, maize is mainly used for feed, but several food specialties were originated during these five centuries of maize history and became traditional food specialties. This review summarizes the state of the art of traditional foodstuffs made with maize in Southern, South-Western and South-Eastern Europe, from an historic evolution to the last research activities that focus on improving sustainability, quality and safety of food production.

Maize ranks first among worldwide production and an important source of human and animal feed. Its production can be affected by management practices and climatic conditions. The objective of this study was to estimate stability of yield and hundred grains weight of six maize genotypes during two growing seasons at two locations, subjected to four different treatments: T1 treatment—without herbicide, Control; T2 treatment—active substance Nicosulfuron and Motivell commercial preparation; T3 treatment—active substance Rimsulfuron and Tarot; and, T4 treatment—active substance Forasulfuron and Equip. Additive main effects and multiplicative interaction—AMMI model and genotype × environment interaction—GGE biplot were used to estimate GEI—genotype by environment interaction. The results showed that the influence of genotype (G), year (Y), locality (L), treatment (T) and all interaction on hundred grains weight were significant. The share of genotypes in the total phenotypic variance was 64.70%, while the share in total interaction was 26.88%. The share of IPCA1 in terms of G × T interaction was 50.6%, while share of IPCA2 was 44.74%, which comprised together 94.80% of interaction. The first IPCA1 axis showed high share in the total interaction, which indicates out significance of genotype in total variation and interaction, while high level of IPCA2 indicates a significant treatment effect. Genotype L-6 had the same mass of 100 grains (37.96 g) during both years of testing, while genotype L-1, with 4.46 g, had the largest difference between years. This clearly indicates the influence of genotype but also stress under the influence of sulfonylureas and environmental factors. The maize genotype with the highest values of hundred grains weight, L-5 and L-6, expressed the highest values of grain yield (4665 kg ha−1 and 4445 kg ha−1).
