Lupin components from 25 experimental paddocks in the Gingin-Dandaragan area were analysed for standard feed components and trace elements in 1961 and 1962-63. Lupinosis had occurred in all the experimental paddocks. Much of this area is deficient in trace elements and lupinosis appeared in 1948 soon after copper-ore topdressing was introduced and the use of superphosphate greatly expanded. The analyses were related to soil types, past dressings of copper and zinc, and compared with general lupin analyses in the district. Protein and calcium in the leaf and seed and calcium to phosphorus ratios in the leaf were high. Cobalt was often below the critical range for sheep health, iron was very high (815-2400 p.p.m. in leaves), organic sulphate was low (mean 0.2 per cent) and manganese was high (mean 326 p.p.m. in leaves). Molybdenum varied widely and was related to past copper and zinc topdressing. It was high in lupin seed where copper-ore topdressings were applied. Copper was marginal for sheep health (3-6 p.p.m.) in leaf and seed and deficient in stems and in associated grasses. Copper was lower and molybdenum higher on paddocks where lupinosis was severe.

Food is a major source of minerals for humans. The main objective of this study was to determine the intake level of 10 essential macro- (Na, K, Ca, and Mg) and trace elements (Cu, Zn, Mn, Fe, Cr, and Se) with major food groups among young adults. Dietary intake of elements was evaluated using the 24-h dietary recall technique in combination with F-AAS and ICP-OES methods. A very high intake of sodium and a very low intake of calcium, combined with inappropriate sodium/potassium ratio, may be harmful to the health of the population. Dietary intake of trace elements was within the range of reference values in the subjects, with cereals being the major source of a majority of those elements, while meat (38% for Na), vegetables (25% for K), and milk products (75% for Ca) were the main contributors to the daily dietary intake of macroelements. PCA revealed several visible trends in the datasetAmong men, the intake of Zn, Cr Na and K was significantly correlated with the consumption of meat and vegetables, whereas Mg, Se, Fe and Cu with cereals and water and beverages. Among women, the intake of Mg was significantly correlated with the consumption of meat and vegetables.

In a field experiment, conducted on four different soil types, trace elements cobalt, zinc, manganese, copper, sodium and molybdenum were applied by sprayer to a grass-legume sward in late September in both 1955 and 1956. Treatment differences were evaluated in terms of total dry matter production and by the chemical composition of the plant tissue. The elements applied were detectable in plant tissue, but herbage yields were not affected. Apparently the trace elements in these different soil types were in the range of sufficiency for maximum herbage production.

Abstract Objectives This study evaluated the nutrients (proximate, vitamins, minerals) and sensory attributes of some products; fried plantain buns (FPB), baked plantain buns (BPB) and steamed plantain buns (SPB) made from over-ripped plantain. Methods A bunch of matured over-ripe plantain samples (3.2 kg) were collected, washed with deionised water, peeled, mashed into pulp. About 400 g plantain pulp were mixed with other ingredients (egg 2 medium size, baking powder (14 g), vanilla flavor (0.5 ml) and onions (13 g) ), fried, steamed and baked respectively. Nutrient composition analysis was carried out in the Food Chemistry Laboratory, University of Nigeria, Nsukka, Enugu State, Nigeria. Sensory evaluations of the three products developed were done in the Food Diet Laboratory using nine-point Hedonic scale with twenty four (24) panellists. Data obtained were subjected to statistical analysis using analysis of variance (ANOVA), Standard deviation and Fisher least significance difference (FLSD) were used to compare the mean at P < 0.05. Results The proximate values of fried, baked, and steamed plantain buns were appreciable. Fat content of fried plantain buns was the highest (12.1%) while steamed plantain buns had the lowest (0.77%). Protein contents were high and comparable in all samples (P > 0.05), the highest moisture content (56.52%) was found in steamed plantain buns. The mineral content shows that Ca, Mg, Fe and Zn levels were comparable (P > 0.05) in all the samples while potassium content ranged from 342.7 to 312.0 mg/100 g with the highest level in SPB. Generally FPB has the highest mineral contents compare with BPB and SPB. Vitamin content in all the samples showed that vitamin C, vitamin A and vitamin E were present. However, there was no significant (P > 0.05) difference among the products. The general acceptability of FPB, BPB and SPB in terms of color, flavor, taste and texture were very high (8.12, 7.12 & 6.71) respectively. Although FPB and BPB were most preferred, SPB was accepted sparingly. Conclusions In conclusion, senescence plantain losses may be reduced if the over ripped ones are converted to buns products and this will consequently add to the value chain and also minimize economic loss globally.

Cassava’s important mineral contents depends on some factors, including genetic and growing locational factors. The study aimed to evaluate the influence of genotype and growing locations on the mineral concentrations in yellow-fleshed cassava root genotypes. Twenty-five pipeline yellow-fleshed cassava genotypes and three white-fleshed varieties (check samples) were planted at five different experimental fields for two seasons, each representing the major agroecological zones in Nigeria. Standard laboratory protocols were employed in the sampling to ensure zero contamination, and the trace and macro elements were determined using the inductively coupled plasma optical emission spectroscopic method (ICPOES). The trace and macro elements identified in all the genotypes and varieties investigated were Fe, Mn, B, Cu, Mo, Co, Ni, Zn, and Al; Ca, Mg, Na, K. P, and S respectively. Genotype and growing location had a highly significant (p < 0.05) effect on all the trace elements except Ti and Cr. However, there was no interactive effect between genotype and growing location on all the trace elements except for Pb and Zn. Among the explanatory variables, the variable growing location was the most influential on macro and trace elements. Conclusively, genotypes 01/1442 and 01/1273 have outstanding trace and macro element concentrations.

Long Term Therapy

The use of trace-elements in intravenous hyperalimentation solutions has been recommended for long-term therapy. Very little information is available concerning the presence of these nutrients as contaminants in commercially available solutions. In view of this, the concentrations of copper and zinc were measured in twenty solutions by atomic absorption. The results indicate that the amounts present may be significant in certain solutions.

The reasons for an increase in barley loose smut in high rainfall areas of Western Australia were investigated in field trials from 1986 to 1988 by examining the effects of environment, cultivar and adequacy of chemical control. Disease was 4-18 times greater in 2 seed lines produced in very high rainfall areas (>750 mm/year) compared with that produced in high (450-750 mm/year) or low (<325 mm/year) rainfall areas. The effectiveness of 5 fungicide seed treatments was assessed. No fungicide seed treatment controlled disease completely. Triadimenol at 225 mg a.i./kg and carboxin at 940 mg a.i./kg were most effective, providing 93-96% disease control. Treatments were significantly (P<0.01) less effective in high rainfall areas of Western Australia. Barley cultivars released recently in Western Australia were found to be susceptible to loose smut; we suggest that the replacement of the moderately resistant Dampier with these cultivars has contributed to an increased incidence of disease.
