The differences observed in the ash contents of taro corm in different studies may be due to climatic effect, soil type, water regime, and plant variety (Azene & Molla, 2017). Further, the caloric values of taro corm were calculated from the crude protein, crude lipid, and carbohydrate (i.e., starch and soluble sugar) contents, as described by Melese et al (2015).…”

Taro (Colocasia esculenta L. Schott) is an important food staple in developing countries in Africa, West Indies, the Pacific region, and Southeast Asia. Because taro can be grown in almost all tropical regions of the world, it will play a crucial role in food security. The use of organic mulches, which contribute to soil water management, weed control, and fertilization simultaneously, shows promise as an eco-friendly approach in agronomy. In the present study, a field experiment including two cropping seasons (I and II) was conducted to evaluate the effects of water regimes with organic mulching on the taro growth and corm nutritive values. In results, compared with that under the upland regime, taro cultivation under the flooding regime had a higher level of soil fertility and better weed control. The flooding regime promoted more the taro plant growth and further enhanced the yields of the harvested corms; also, sugarcane bagasse and rice husk would be the superior mulch to obtain better corm attributes. By contrast, cultivation under the upland regime enhanced the nutritive values of taro corm more than did that under the flooding regime. Regardless of the upland or flooded regime, mulching treatments with rice husk could enrich taro corm nutrition more than could those with sugarcane bagasse and peanut hull. Also, the effects of water regime and mulching on taro plant growth and corm attributes would be varied with the rainfalls during the period of vegetative growth.

“…The Fe content of the studied WEPs in this study is comparable with the Fe contents of WEPs in Southern Ethiopia and falls between 1.9 mg/100 g in Ximenia caffra to 22.0 mg/100 g in Launaea intybacea [21] and is greater than the Fe contents of Colocasia esculenta (10.57 mg/100 g) in Wolaita Zone, Ethiopia [38]. The high iron content of WEPs in the study area suggests that plants could be a good dietary source of iron, contributing between one and 1.5 times the adult RDA of 18 mg/day, but its bioavailability may need to be evaluated further [40,41]. Zn content is highest in the leaves of H. rueppelii (23.87 mg/100 g DW) and least in the leaves of A. hybridus (8.35 mg/100 g DW).…”

Wild edible plants (WEPs) are the natural food source that can help to mitigate food insecurity and improve starvation in low income countries including Ethiopia. Despite the widespread use of WEPs in Ethiopia, studies on the nutritional contents of Ethiopian WEPs are limited. The objective of the current study is to evaluate the nutritional value (proximate, mineral, and vitamin C contents) of the most consumed seven wild edible plants collected from Lasta District, Northeastern Ethiopia. The nutritional parameters including proximate, macro and micronutrients, and also vitamin C contents of the selected seven wild edible plants were evaluated using standard food analysis methods (moisture by dry-oven method, ash by high-temperature incineration in an electric muffle furnace, fat by Soxhlet extraction procedure, protein by Kjeldahl process, minerals by Atomic absorption spectrometer and atomic emission spectrometry and vitamin C by using a spectrophotometer). One-way ANOVA was used to analyze the nutritional content variations of selected WEPs. The proximate composition of the 7 WEPs came in the respective ranges of moisture (6.50–9.77 g/100 g); ash (6.99–26.35 g/100 g); crude protein (13.1–33.63 g/100 g); crude fat (1.08–9.83 g/100 g); crude fiber (6.21–43.77 g/100 g); utilizable carbohydrate (30.11–66.25 g/100 g) and gross energy (213.05–414.80 Kcal/100 g). The mineral composition of WEPs (mg/100 g dry weight) for macronutrients ranged from 25.53–37.99 Na, 56.65–72.79 Mg, 14.40–43.57 K, 44.35–60.14 Ca, and for micronutrients it ranged from 10.51–27.96 Fe, 8.35–23.87 Zn, 14.08–23.20 Cu, and 7.99–19.08 Mn. The vitamin C contents of WEPs (mg/100 g dry weight) ranged from 2.16–70.42 except in Haplocarpha rueppelii leaves in which its vitamin C content is below the detection limit. The outcome of the investigation indicates that the proximate, mineral and vitamin C contents of the WEPs included in the analysis were higher than those of some common crops (sorghum, rice, wheat, barley and maize), indicating their nutritional contribution to the human diet in the studied area. These wild food sources make up a good part of the traditional subsistence system of the people of Lasta District alongside their common food crops and other food sources.

The study was carried out to determine the nutritional and anti-nutritional composition of taro genotypes and also determine the phenotypic plasticity of the genotypes in two agro ecological zones in Ghana. The towns and zones were Bunso in the semi deciduous forest (an upland) and Tano Dumasi in the forest savannah transition agro-ecological (a waterlogged area) zone in the Eastern and Ashanti regions respectively.Two (2) freshly harvested corms of each genotype from each location were assessed for their nutritional (moisture, protein, carbohydrate, ash and fat) and anti-nutritional (phytate, oxalate and tannin) composition Data collected were subjected to analysis of variance and AMMI analysis using GenStat 12 edition to assess the effect of genotype, environment and their interaction on the traits studied. Phenotypic plasticity for the genotypes and the traits studied was also calculated. Pearson correlation was also conducted to assess the relationship between the traits studied. There were significant differences among the genotypes for nutrient and anti-nutrient composition except for percentage fat, indicating enough genetic variability among the genotypes, giving room for good selection progress for development of taro varieties. A higher magnitude of the environment over genotype and genotype by environment interaction observed indicates the influence of environment in the expression of the nutritional and anti-nutritional traits. Observed varied phenotypic plasticity among the genotypes for the nutrient and anti-nutrients composition also indicates varied adaptation of the genotypes to the environment. Genotypes BL/SM/115, CE/MAL/32 and CE/IND/16 and hybrids KAO19 × CE/MAL/32 and CE/IND/16×KAO19, CE/IND/16 × BL/SM/10, and CE/IND/16 × BL/SM/115 which recorded high nutrients and low anti-nutrients content and were stable across the environments can be released to farmers for cultivation. They could also be included in breeding programs for the development of enhanced nutritional quality of taro in Ghana.
