Abstract: Hibiscus sabdariffa commonly known as “roselle” is a member of malvaceae family. It is a plant with a worldwide fame and has more than three hundred species which are distributed in tropical and subtropical regions around the world. Many parts of Roselle including seeds, leaves, fruits and roots are used in various foods as well as in herbal medicine. This research work analyzes the nutritional composition of dried Hibiscus sabdariffa leaves and calyces. The moisture content was determined by exposing the sample to heat under controlled conditions, the water from the material evaporated leaving the dry matter. The ash content was determined by burning off the organic matter leaving behind inorganic ash. Base on the principle that non-polar components of samples are easily extracted into organic solvent, crude lipid was determined using n-Hexane. The protein content was obtained by Kjeldahl method. Mineral analysis was also carried out to determine the amount of Potassium, calcium and phosphorus. The result shows that the dried leaves and calyces of Hibiscus sabdariffa contain: Moisture: 12.50% and 10.50%, Ash: 14.50% and 11.67%, fibre: 0.83% and 1.17%, Crude lipid: 4.33% and 1.00%, Crude protein: 5.37% and 4.10% respectively. The mineral content of the leaves and calyces were; Calcium: 1.40% and 1.20%, Magnesium (mg/g): 1.35% and 1.57%, Phosphorus: 5.00% and 5.485% respectively. The leaves, of the plant can be used as vegetable to make soup and other dishes, Drinks made from Roselle calyces should be consumed regularly as it is safe, natural and nutritious.

Abstract: To examine the effect of variety and different level of potassium (K) on yield of jute, an experiment was conducted at the Agronomy Field Laboratory, Patuakhali Science and Technology University, Dumki, Patuakhali from May to September 2016 using three variety viz. C-2197, C-3069 and C-3473. There are four levels of K viz. 0, 35, 45 and 55 kg ha-1. The land was fertilized as per treatment specifications from muriate of potash along with recommended doses of urea, TSP, gypsum and zinc sulphate. The experiment was laid out in randomized complete block design (RCBD) with three replications. The variety O-3069 had significant influence on number of internodes per plant (64.20), plant diameter (21.15mm), fiber weight per plant (25.92g), fiber yield (5.18t ha-1), stick weight per plant (64.75g) and stick yield (12.94t ha-1). The highest results of plant height (3.81m) and green weight with leaf (4.04kg/10 plant) were obtain from C-3473 and green weight without leaf (3.54 kg/10 plant) were obtained from C-2197. Among the different potassium levels 55kg K ha-1 had significant influence on number of internodes per plant (70.13), plant diameter (22.60mm), green weight with leaves (4.43kg/10 plant) and green weight without leaves (3.91kg/10 plant), fiber weight per plant (27.93g), fiber yield (5.59t ha-1), stick weight per plant (69.60g) and stick yield (13.90t ha-1). The highest plant height (4.13m) were obtained from 35 kg K ha-1. The variety O-3069 with 55kg K ha-1 had significant influence on plant diameter (24.00mm), fiber weight per plant (31g), fiber yield (6.2t ha-1), stick weight per plant (77.53g) and stick yield (15.50t ha-1). The highest results of plant height (4.30m), number of internodes per plant (73), green weight with leaf (4.85kg/10 plant) and green weight without leaf (4.25kg/10 plant were obtain from C-3473 with 55kg K ha-1. The results of the present experiment showed that the C-3069 was the best among the varieties. On the other hand, 55kg k ha-1 was proved to be better than any other lower and higher levels of potassium. Therefore, it can be inferred that jute can produce the highest fibre yield from a combination of variety C-3069 with 55kg k ha-1 in field under the coastal region of Bangladesh.

Abstract: Moringa oleifera is one of the green leafy vegetables that are under-exploited and under-utilized. Available researches have shown that Moringa oleifera is rich in nutrients and can be used as a food-based strategy in combating nutrient deficiencies. The study was carried out to comparatively evaluate some nutrient contents of Moringa oleifera processed under different methods. The research analyzes and compares nutritional composition of dried and cooked Moringa oleifera leaves. The moisture content was determined by exposing the sample to heat under controlled conditions, the water from the material evaporated leaving the dry matter. The ash content was determined by burning off the organic matter leaving behind inorganic ash. Base on the principle that non-polar components of samples are easily extracted into organic solvent, crude lipid was determined using n-Hexane. The protein content was obtained by Kjeldahl method. Mineral analysis was also carried out to determine the amount of potassium, magnesium, sodium, calcium and phosphorus The results shows that, the dried leaves of Moringa oleifera and cooked leaves contain: Moisture 3.0% and 5.0%, Ash 13.5% and 10.0%, fibre 8.5% and 10.0%, Crude lipid 5.0% and 7.5%, Crude protein 5.43% and 9.98%, Carbohydrate 62.57% and 59.52% respectively. The mineral content of the leaves (mg/100g): were Sodium (Na) 0.14 and 0.08, potassium (k) 5.10 and 2.60, Calcium (Ca) 0.28 and 0.22, magnesium (Mg) 0.29 and 0.25, phosphorus (P) 5.58 and 4.91 respectively. The results showed that, the cooked leaves of Moringa oleifera contain more nutrients than the dried leaves. However, carbohydrate and mineral composition are lower in the cooked leave. Nutrient loss is a consequence of nearly every cooking process. Exposure to heat, light or oxygen alters the nutrients found in food, and methods that involve water often reduce the amounts of nutrients as these get ‘washed out’ and left behind.

Abstract: A field trip was carried out in Kafta Humera wereda Adigoshu Tabia (administrative unit below wereda), adjacent to Kafta-Sheraro National Park, to assess the presence of plant and their derivative use of different use values practiced by the local community. The study employed ethnobotanical methods including structured and semi-structured interviews, field observations, preference ranking, relative frequency and fidelity level. A total of 50 informants from both ethnic groups (Habesha and kunama) Tabia were selected purposively and 28 key informants also selected with the help of local administrators, recommendations from elders, and members of the local community. A total of 36 plants with their ethnobotanical use were collected and identified. These species represent 34 genera and 27 families. About 29 of the medicinal plants were used to treat for human disease only, 2 medicinal plant only for animal and 5 medicinal plants for both animal and human diseases. The main source of those plant species was obtained from wild (83%) while 17% of the species were cultivated. Of the total 36 medicinal plants collected from the study area, the habit of a plant where about 69% trees followed by shrubs (22%), climbers (6%) and herbs (3%) in their decreasing order. The most commonly used plant parts were leaves and followed by root and fruit part in equal ranks. There was no uniform measurement used by the local healers in the study area. Female were more involved in selling the edible and medicinal plants than males.

Abstract: Potato has lived with several diseases and insect pests such as late blight and potato tuber moth for several decades. However, newly emerging insect pest known by the name 'mealybugs' is recorded as a new threat for potato production in the highlands of Arsi, Southeast Ethiopia. This pest has never been observed in the area in the history of potato culture in which potato has been grown for many years. Therefore, awareness creation should be the primary step by which any respective stakeholders including potato growers, research institutions, ministry of agriculture; NGOS, etc. are informed about the importance of the pest. This will help to look for appropriate management options and take the necessary precautions before the pest becomes important in other areas in the country.
