This study therefore aims at evaluating the combined effects of cassava peel compost with poultry manure and mineral fertilizer on growth and yields of Corchorus olitorius. Pots （factorial laid out in a randomized complete block design） and field （split-plot with fertilizer being the main effect and the varieties the sub plot effect） experiments were carried out during rainy season at Ibadan, Nigeria. Treatments consisted of 0, 5, l0 and 20 t/ha composts prepared from cassava peel and poultry manure in ratio 3：1 and mineral fertilizer （NPK 15：15：15） at the rate of 250 kg/ha, using two varieties of C. olitorius. Five and six weeks after planting （WAP）, plants were assessed for growth and yields in pot and field experiments respectively, and also in residual studies. Application of compost significantly improved growth （heights） （36.50-41.56 cm）, while morphological and dry weight values increased with increase in compost. Marketable yield increase of 13.2%, 22.3%, 32.1% and 29.3% were recorded using 5, 10, 20 t/ha compost and NPK fertilizer respectively in the field. Corresponding increase when ratooned were 40.0%, 42.9%, 57.1% and 52.0%, respectively. Application of compost at the rate of 20 t/ha performed better in the main and residual effect experiments compared to NPK fertilizer and other compost rates. Application of cassavas peels compost at the rate of 20 t/ha proved to be adequate for optimum growth and yield performance of C. olitorius.展开更多

These plants are widely consumed by Chadian population, but few research studies have focused on their nutritional and health benefits. The aim is to stimulate research, investment, and in-depth studies on these plants to encourage their use and transformation in Chad. Abelmoschus esculentus, Hibiscus sabdariffa, and Corchorus olitorius L. are Malvaceae species with medicinal properties and traditional use in Chad. They contain essential amino acids and have antinociceptive, anxiolytic, anti-inflammatory, and anxiolytic activities. Their extract has hypoglycemic potential as a preventative or adjunct therapy for pre-diabetes or diabetes. Hibiscus sabdariffa is rich in essential vitamins, including vitamin A, which is beneficial for eyes, anti-aging, and sight. Its vitamin C helps fight free radicals and ensures good resistance to infections. Corchorus olitorius L. has a nutritional composition ranging from 1.2 to 34.4 mg/100 g and is known for its mucilaginous seeds, young tops and leaves, and silky hair. These plants have potential medicinal applications in antidiabetic, anti-gastritis, and prebiotic fields, and play a significant role in neural development and health. Promoting their use in Chad requires conservation programs, public policies, and local population planting. Future research should focus on their nutritional and medicinal properties, targeting underutilized species to address micronutrient deficiencies. Enhancing bioconservative properties and communication of these plants’ virtues are crucial for their optimal availability and protection.展开更多

It has been generally accepted that the polysaccharides derived from botanical extracts increase skin hydration. Since skin hydration improves skin barrier function, it is one of the most effective treatments for atopic dermatitis (AD). However, other components of botanical extracts other than polysaccharides may influence skin hydration and transepidermal water loss (TEWL). The aim of this study was to evaluate the hydration efficacy and skin barrier protection afforded to the skin after exposure to Corchorus olitorius extract without high-molecular-weight compounds (COEW), such as polysaccharides. Methods: NC/Nga mice possess disrupted skin barrier function, and were used as a model for AD. A stable base cream was supplemented with 0.2% COEW and applied to the dorsal skin of these mice. Skin hydration and TEWL were analyzed after a 14-d period of daily application. AD scores and plasma immunoglobulin E (IgE) concentrations were also investigated. Results: Compared to control mice, mice treated with the COEW cream showed significantly increased skin hydration and reduced TEWL. Plasma IgE concentrations were not affected by the COEW cream, whereas an increase in AD score in NC/Nga mice was prevented because of the application of the COEW cream. Conclusions: COEW has the ability to maintain hydration of the skin, and to prevent the disruption of skin barrier function, which leads to the aggravation of AD. COEW may be used as an adjunct treatment for AD.展开更多

This is a laboratory-based experiment involving optimization of amount of urine and dilution required for optimal growth of the test plants. Based on laboratory results, the experiments were scaled up. About 50 L of raw urine was collected from a male postgraduate student’s hall of residence, University of Ibadan, Ibadan, Nigeria. Water from Awba Dam, a natural lake within University of Ibadan, was used as the control. Viable seeds of Amaranthus viridis and Corchorus olitorius were collected from Department of Agronomy, University of Ibadan, and germinated in a nursery for 10 days before transplanting. The raw urine was diluted with varying amount of water in the ratio 1:1 through 1:50. Nutrients in urine media (nitrogen, phosphorus, potassium) and biomass indicators of plant growth (height, weight, number of leaves and leaf area) were determined using standard procedures. Urine dilution ratios below 1:25 did not support the experimental plants growth within a week. Plant height (cm), stem girth (cm), number of leaves (sheets) and leaf area (cm2) of Amaranthus viridis and Corchorus olitorius cultivated on Urine Dilution Ratio (UDR) 1:35 and 1:45 were higher at the end of week 3 compared to other dilutions and control. Percentage reduction of nutrients (NPK) in the media of Amaranthus viridis cultivated on UDR 1:45 was several folds higher (N = 59.9%, P = 100%, K = 55.3%) compared to that of UDR 1:35 (N = 38.5%, P = 49.1%, K = 37.6%). In the control water, the nutrients were totally removed during the experimental period. Growth of Corchorus olitorius cultivated on both UDR 1:35 and 1:45, was significantly higher at the end of week 6. A significant negative correlation was observed between Corchorus olitorius plant height and Phosphorus (r = -0.0418;p < 0.05) removal in the media. The study concluded that the use of diluted human urine for soilless cultivation of vegetables, if encouraged, could promote food security and environmental sustainability at household level in communities.展开更多

Salt Iodisation has been the common approach to solving these problems. However, apart from the problems of lack of compliance by salt manufacturers, and inculturation of the consumers, health conditions aggravated by high salt intake by humans have become increasingly relevant. These problems can be eliminated if the commonly produced and consumed plants are fortified with Iodine. The prospects are in the inclusion of Iodine-containing compounds in the inorganic fertilizers used by farmers. In this study, Potassium Iodide and Potassium Iodate were used as inoculants. Five different concentrations—0.1 M, 0.2 M, 0.3 M, 0.4 M, and 0.5 M of Potassium Iodide and Potassium Iodate solutions were used to inoculate the soils on which the following edible African plants were planted: Murraya koenigii;Ocimum gratissimum;Cucurbita pepo;Solanum nigrum;Amaranthus hybridus and Abelmoschus esclentus, Corchorous olitoruis, Solanum lycopersicum, Zingiber officinale, Telfairia occidentalis, Talinium triangulare, Solanum melongena. Controls were also planted. After 14 days, alkaline dry ash method was used to determine the Iodine concentrations in the plants. The results showed that Murraya koenigii showed the highest absorption of Iodine 6.90 mg/kg at 0.3 M using KI, followed by Amaranthus hybridus 6.40 mg/kg at 0.1 M. Solanum nigrum, Ocimum gratissimum and Zingiber officinale also showed good absorption. Other plants except Murraya koenigii, Ocimum gratissimum, Solanum nigrum and Zingiber officinale showed very low tolerance to KI absorption. The result also showed that Telfairia occidentalis showed the highest absorption of iodine 8.20 mg/kg at 0.2 M of KIO3 followed by Cucurbita pepo 6.40 mg/kg at also 0.2 M of KIO3. Murraya koenigii, Ocimum gratissimum, Solanum nigrum, Zingiber officinale also showed good absorption of KIO3. Some of the plants were not able to tolerate the absorption at higher concentration for both KI and KIO3. All the plants were poisoned at concentration of 0.5 M for both Ki and KIO3. Murraya koenigii, Ocimum gratissimum, Solanum nigrum, Zingiber officinale can be used in iodine biofortification using KI and KIO3 at concentration < 0.5 M. The overall result may be very significant, when it is considered that Iodine is a micronutrient, with a daily intake requirement of 100 - 150 μg/kg. It can be seen that there is hope in achieving this kind of biofortification.展开更多
