Nutritional Evaluation of Five African Indigenous Vegetables

Abstract The promotion and consumption of indigenous vegetables could help mitigate food insecurity and alleviate malnutrition in developing countries. In this respect, 17 accessions (candidate breeding lines that have not yet officially been released) of five African indigenous vegetables: amaranth (Amaranthus cruentus), nightshade (Solanum scabrum), African eggplant (Solanum aethiopicum), jute mallow (Corchorus olitorius) and okra (Abelmoschus callei), previously selected for their superior agronomic and horticultural traits, were evaluated in Cameroon for minerals (Ca, Mg, K, P, Zn and Fe), proteins, and carotenoids content. Nutrient content differed significantly (P<0.001) between cultivars. Amaranth (especially line AM-NKgn) had the highest Ca, Mg, and Zn content in comparison to other genotypes studied. Nightshade had the highest K and Fe content. The highest K and Fe levels were found in nightshades BG24 and SS52, respectively. Nightshade had the highest level of protein, especially line BFS1. The highest amount of carotenoids was identified in the eggplant variety Oforiwa. The study revealed that these vegetables are important sources of some vital nutrients. Increased production and consumption of these nutrient-rich vegetables will help reduce the nutrition-related disorders in Africa.

Enhancing Production

The study analyses the efficiency of communication strategies used by Farm Concern International (FCI) in enhancing the production and consumption of African Indigenous Vegetables in Lari Sub-County, Kenya. The study used both quantitative and qualitative research designs and used purposive sampling, followed by random sampling to select 100 farmers from the five villages in Lari Sub County. The data was gathered from the primary sources through the use of structured questionnaire for both quantitative and qualitative. The data was then processed and presented by the use of graphs, tables and pie charts and analysed by use of descriptive analysis. The study used two theories, Rational Argumentation Theory propounded by Cragan and Shields (1998) and Trans theoretical Model (TM) by Prochaska, Johnson and Lee (1998). The study established that the rate of AIVs production has increased since the implementation of DoHoMa Project. The rate of consumption has also increased with the majority of farmers eating AIVs on a daily basis due to their higher nutritional value. Only a few who consumed the value chain three to six times a week. The findings also indicated that FCI majorly used two forms of Ora-Media, barazas and demonstrations, to promote production, consumption and commercialisation of AIVs. The study recommends that agriculture-based NGOs need to use more of demonstrations than barazas because most of the farmers have basic education. The Ministry of Agriculture needs to facilitate farmers to dig boreholes for enhancing irrigation during dry spells.

African indigenous vegetables (AIVs) have recently received wide attention for their contribution toward food and nutrition security. Promoting the production and consumption of AIVs is likely to mitigate food insecurity and alleviate malnutrition in the African region. To document and analyze existing patterns of AIV production in Zambia, farmers were surveyed in person using a structured questionnaire. A total of 300 farmers were selected from Lusaka (50), Katete (50), Chipata (75), Lundazi (75), and Petauke (75). Analysis of the survey results using logit model identified that those who farm less than 10 acres of farming land, were concerned about nutrition quality of AIVs, reported that price of farm produce is fixed by buyers, were registered as a member of any community group or association, received training related to nutrition and health, saved money for unexpected expenses, and were single are more likely than other farmers to produce AIVs for home consumption. Whereas, those who visited the nearest market two times or more, traded agricultural produce through intermediaries, owned a TV, earned an income above 30,000 kwacha and has a University degree are less likely to produce AIVs for home consumption. These results indicate that interventions aimed at increasing AIV production for home consumption should target specific groups of farmers rather than all farmers. This survey also captures the most common AIVs that are grown in these regions in Zambia: Sweet potato leaves, amaranth and orange sweet potato.

The main objective of this study was to assess the pollen effects on macro and micro nutrition elements on hazelnut cultivars (Corylus avellana L.). Tombul, Palaz, Çakıldak, Foşa and Allahverdi were used as main cultivars while Tombul, Palaz, Çakıldak, Foşa, Allahverdi, Sivri, Kalınkara and Yassı Badem were used as pollinator cultivars. In the study, it was investigated that the pollinator cultivars caused changes in some nutrition elements. The effects of the applications on nitrogen, phosphorus and potassium content were found to be statistically significant. It was determined that the nutrition element with the highest rate in the examined hazelnut cultivars is potassium. It has been observed that the amount of potassium is high in Tombul-pollinator treatments. The potassium content of Foşa and Çakıldak weres found to be higher than other cultivars. In Palaz and Yassı Badem- pollination treatments, it has been observed that the Ca content is generally lower than other treatments. Fe content was found to be significantly higher in Palaz-pollination treatments. The highest Mn and Zn content was obtained from Çakıldak. As a result, it has been revealed that pollinators may have an effect on nutrient content.

Set Up

Zinc scrap is a source of raw material for zinc oxide production. However, to qualify the requirement of raw material for zinc oxide (99.5%) production, refining this source is needed. Many methods are considered such as rectification, chemical method, etc., but difficult to apply on an industrial scale. This workfocused on the investigation of the influence of temperature and time factors for asessing the possibility of applying liquation method for the purification of impurities from scrap zinc.The experiment results show that the optimum temperature of liquation to remove Pb,Fe from zinc scrap is in the range of 440-450°C, the optimal time of the process is 8h for the pot with 8cm in height and 6cm in diameter (the quantity of raw zinc sample is about 2kg / batch), then we can obtain about 80% of zinc metal with an average Zn content of about 97, 0%, both Pb and Fe content decreased to a range from 0.35 to 0.4%, and 1.0 to 1.1%, respectively, which meet the requirement of raw materials for the production of high quanlity ZnO ( 99,5 %). Based on the parameters obtained on lab-scale, a trial on pilot scale of 250 kg / batch was conducted, The result confirms that the quality of the products meets the requirement of raw materials for production of high quality ZnO (99.5%) and a technology process for refining zinc scrap by the liquation was proposed.
