“…After cooling, the solutions were quantitatively transferred to graduated centrifuge tubes and diluted to 50 ml final volume with deionized water. The samples were analysed by inductively coupled argon plasma atomic emission spectroscopy (ICP-AES, Jarrel-Ash) for trace metal content as described elsewhere (Yazzie et al 1994;Kim et al 1997) and quantified against standard solutions of known concentrations that were analysed concurrently. This digestion technique makes no attempt to solubilize any silicate-based materials that may be in the samples.…”

For the Makiritare (Ye'Kuana) native people of the Alto Orinoco (Venezuela), earthworms (Anellida: Glossoscolecidae) are an important component of the diet. Two species in particular are widely consumed: 'kuru' (Andiorrhinus kuru n. sp.) and 'motto' (Andiorrhinus motto). We analysed eviscerated kuru body proper, and whole and smoked preparations of motto for their content of protein and amino acids, fatty acids and 20 minerals and trace elements.The samples contained large amounts of protein (64.5-72.9% of dry weight), essential amino acids, calcium and iron together with notable quantities of other important elements, indicating that these earthworms contain potentially useful quantities of many nutrients that are critical to the health of the humans who consume them.

“…The composition of the amino acids in the leaf protein is well balanced (Foidl et al 2001). The available data (Yazzie et al 1994;Nordeide et al 1996) show that leaves contain 13-15% protein, 60-70% carbohydrate, 4-10% fat, around 11% fiber, 16% ash and the energy value varies from 1180 to 1900 kJ/100 g of which 80% are metabolisable energy.…”

Purpose The need for increasing production of Moringa oleifera in Nigeria can be achieved through adequate fertilization. This study investigated the effects of sources and rates of NPK (15:15:15) and compost on soil properties and productivity of Moringa at National Horticultural Research Institute, Ibadan, Nigeria. Methods NPK was applied at 30, 60, and 90 kg N/ ha, cow dung (CD), poultry manure (PM) and organomineral (OM) were applied at 10, 20 and 30 tons/ha. The experimental design was a randomized complete block design with three replicates. Organic fertilizers were incorporated into the soil 2 weeks before sowing; NPK was split applied at 2 and 5 weeks after sowing. Seeds were sown at 75 cm 9 75 cm spacing. Data were taken on plant height (cm), stem girth (cm), number of leaves, leaf biomass, stems weight and post-planting soil properties.Results Growth values for NPK and compost treatments were higher than the control. PM applied at 30 tons ha -1 resulted in highest growth values: plant height (65.91 cm), stem girth (1.51 cm) and number of leaves (14.20). PM applied at 30 tons ha -1 gave higher stem weight (2249.9 g) and leaf biomass (3610.5 g). Post-planting soil analysis indicated that nitrogen, phosphorus, calcium, sodium, manganese, iron and zinc contents were higher in plots with organic and inorganic fertilizers except for potassium and magnesium.Conclusion PM proved more superior to CD manure and others because it produced better growth attributes such as shoot height, stem girth and number of leaves and leaf biomass than its counterparts produced.

“…Comparatively, in all the three samples, zinc, copper, iron and manganese were markedly detected. Since iron deficiency (anaemia) is common in African region where baobabs grow, the leaves represent an important source of iron [17,23]. The result suggests that shade-drying is the most appropriate method for optimal iron content.…”

Abstract-Baobab (Adansonia digitata) leaves are usually used in dry form in the preparation of a soup known as 'miyan kuka' in Northern Nigeria. The leaves are believed to have nutritional and medicinal benefits and have been used for those purposes in Africa and Asia. However there has been limited research on the detailed constituents of the dry leaves. In this study, phytochemical, elemental and proximate analyses of stored, sun and shade-dried baobab leaves were conducted. The results revealed a great variation in the nutritional contents of the leaves. The study reveals that the leaves are rich in phytochemicals such as glycosides, saponins, steroids and flavonoids while alkaloids, tannins and resins are absent. Also, they are important source of minerals such as zinc, copper, iron and manganese. In addition, they are rich in fibre, crude protein, nitrogen and ash. Contrasting responses were obtained in the samples studied. The implications of these responses are discussed in relation to crop yield.
