“…As a whole, tested accessions resulted shorter than how obtained by Sogbohossou and Achigan-Dako [ 6 ] on 27 A. cruentus accessions (136.9 ± 25.9 cm). Casini and La Rocca [ 40 ] found a plant height ranging from 106 to 127 cm on 10 A. cruentus accessions, while Maseko et al [ 41 ] in a two-year study, obtained a plant height ranging from 70 to 100 cm.…”

Agronomic traits, oil content, fatty acid composition, antioxidant activity, and total phenolic content were studied on eight A. cruentus accessions cultivated in Southern Italy. A one-way ANOVA model was performed to compare accessions and the Principal Components Analysis was applied to identify patterns in our dataset and highlight similarities and differences. A. cruentus showed valuable seed yield (0.27 kg/m2, on average) comparable to the main tradition cereals used for animal feeding. Seed-oil composition showed significant differences among the accessions. Data showed a higher lipid content than most cereal grains (from 5.6 to 7.3%). Approximately 60% of fatty acids were unsaturated; linoleic fatty acid ranged from 19 to 34%, oleic acid from 29 to 36%, and alfa-linolenic fatty acid from 0.3 to 0.5%, respectively. The saturated/unsaturated fatty acid ratio ranged from 0.5 to 0.8, the hypocholesterolemic:hypercholesterolaemic ratio from 1.7 to 2.7, the Atherogenic Index from 0.38 to 0.66, the Thrombogenic Index from 0.85 to 1.48, the total phenolic content from 0.14 to 0.36 mg/g seeds, and the antioxidant activity (DPPH•) from 0.30 to 0.50. The studied seed-oil composition evidenced A. cruentus as a healthy ingredient for animal feed and consequently, as a possible substitute for traditional cereals. Accessions from Mexico and Arizona emerged for their high qualitative traits.

“…Application of 60% ETc enhanced nutritional content of ALVs while the concentration of nutrient under water stress indicated drought tolerance [68] The selection of germplasm for conservation and identification of parental genotypes, usually referred to as pre-breeding, is the foremost step in plant breeding. In this study, 14 articles explored the genetic diversity within different ALV species.…”

African Leafy Vegetables for Improved Human Nutrition and Food System Resilience in Southern Africa: A Scoping Review

et al. 2021

The economic potential of African leafy vegetables (ALVs) remains obscured by a poorly developed value chain. This scoping review assembled and examined scattered knowledge generated on ALVs across southern Africa, focusing on production, processing, marketing, and consumption. Two electronic databases (Scopus and Web of Science) were screened, and a total of 71 relevant studies were included and evaluated. The review provides a state of the art on knowledge related to utilisation of ALVs across the entire value chain. The findings show that functional properties are of prime importance in the production and consumption of ALVs. However, the lack of improved germplasm and a non-existent seed supply system are significant production bottlenecks. Pests and diseases affecting the productivity of ALVs remain mostly unexplored. Sun-drying and boiling were the most reported post-harvest processing methods, suggesting that traditional processing methods are still prominent. Many studies also confirmed the predominance of informal markets in the trading of ALVs as they fail to penetrate formal markets because of poor product positioning and exclusion from produce demand and supply forecasts. The inception of cultivar development, mechanised processing methods, and market linkages will enhance the profitability of ALVs in the region. This review enhances the gaining of insight into the state of different value chain components will assist in upscaling production, value addition of products, and enhance marketing efficiency. There is a great opportunity for basic and applied research into ALVs.

“…N application enhanced morphological traits and yields of amaranth crops (A. hybridus and A. hypochondriacus) effectively, whereas the optimum rate of N fertilization had to be amended for the demand of each amaranth crop (Ayodele 2002). As speculated by Maseko et al (2019), the optimum rate of N fertilizer promotes the development and yield of the amaranth crop and reduces N loss, while Gélinas and Seguin (2008) implied that N application just modulated plant height rather than yield in A. caudatus. The growth parameters of A. viridis cultivated at all N concentrations showed that N application increased plant height and shoot and root DM significantly (Table 1), but the promotion of growth parameters in MN and HN was insignificant.…”

“…Moreover, a previous study indicated that the plant height of the amaranth crop is positively correlated with the level of nitrogen fertilization, but its yield is unresponsive to fertilization level (Gélinas and Seguin 2008). Recent research suggests that moderate N fertilization promotes agronomic traits and yield in the amaranth crop (Maseko et al 2019). In addition, a high N supply with temporal variability might increase plant growth dramatically (Wang et al 2022).…”
