  • Effect of Packaging Materials on Post Harvest Quality of Avocado (Persea
           Americana) at Wolaita Sodo University in , Ethiopia

    • Authors: GEBRE Garmame
      Abstract: The experiment was conducted in laboratory in April 2016 at  Wolaita Sodo University, Ethiopia .The objectives of the study were to evaluate the effect of different packaging materials on  post harvest quality of avocado fruit and to identify the best packaging materials. The treatment was contain four packaging materials viz, control (floor), dried banana leaf, carton plus newspaper and plastic polyethylene. The experiment was laid out in complete block design with three replications. Data were recorded on post harvest qualiy parameters  such as total soluble sugar, total weight loss, decay percentage, titratable acidity and shelf life assessment and analyzed by using statistical software. The result showed that there were a significant difference among all used packaging materials on total soluble sugar and decay percentage, while there were no significant difference among carton plus newspaper and dried banana leaf on total weight loss, titratable acidity and shelf life assessment. Avocado fruit packed in plastic polyethylene has the most long shelf life (14days) than packed in cardboard plus newspaper (10days), dried banana leaf (9days) and floor (control)(6).It can be concluded that avocado fruit stored in plastic polyethene bag prolong the shelf life of avocado than other packaging materials. so, plastic polyethylene bag was recommended. Due to the limitation of our laboratory materials we have used only four treatments; it would be advisable to repeat the experiment by using additional packaging materials to come up a comprehensive recommendation. Keywords: Avocado, packaging materials, post harvest quality parameters

  • Effect of Application of Farmyard Manure and Gypsum on Saline Sodic Soils
           of Raya Alamata District, Northern Ethiopia

    • Authors: Birhane Hailu; Hagos Mehari
      Abstract: A field experiment was conducted in Raya Alamata district, northern Ethiopia  to investigate the effect of sole and combined application of FYM and gypsum on saline sodic soils on yield of sorghum by supplying different rates of farmyard manure (FYM) and/or gypsum (CaSO4.2H2O) application alone or both mixtures using a randomized complete block design for three consecutive years. The treatment used included: control, three FYM rates alone, two gypsum rates alone and six combination of FYM and gypsum with a total of 12 treatments. Each treatment was replicated three times to yield 36 experimental plots. The result indicated that, there was no significant difference between treatments in the first and second year of cropping season. However, the effect the amendments were shown in the third year of the cropping season, and hence, the treatment effect of the combined application of FYM and gypsum were more effective and improved soil properties and increased the yield of sorghum. In addition, compared to all other treatments, the combined application of 4 tha-1 FYM + 100% GR followed by  8 tha-1 FYM + 100% GR resulted the highest grain yield of sorghum  and reduced the sodium induced hazards than all other treatments. Hence, it is recommended as the best treatment in the improvement of saline  sodic soils of the district. Keywords: Gypsum; Farmyard manure; Sorghum; Soil amendment; Soil properties

  • Anti-Malarial Activity and Toxicological Effect of Combined Corymbia
           Citriodora, Maytenus Senegalensis and Warbugia Ugandensis as Used in
           Traditional Medicine in Kenya

    • Authors: Sarah Atambo, Peter K. Njenga, Festus Tolo
      Abstract: Malaria is majorly caused by Plasmodium falciparum resulting in thousands of deaths every year. In Africa, it is a key contributor to the disease burden notable in the disability adjusted life years (DALYs). About 243 million individuals are at a risk of contracting the disease and a higher rate of deaths are observed in children under the age of five. Conventional drugs are available at a subsidized rate but the rising problem is the resistance of the plasmodium parasite to these drugs. Hence, there is an urgent need for the development of new and alternative therapeutics for treatment of malaria. In some regions in Kenya, parts of locally available plants are harvested and used for treating malaria. It is estimated that locally, 30% of the population relies on traditional medicine for treating various ailments due to the lack of infrastructure and accessible medical facilities especially in the rural areas. Warbugia ugandensis, Maytenus senegalensis and Corymbia citriodora are amongst the plants used in herbal medicine for the treatment of malaria. However, their combinatorial antimalarial efficacy and safety is yet to be determined hence the aim of this study. The plants were harvested from their natural habitats and transported to the Centre of Traditional Medicine and Drug Research (CTMDR) at the Kenya Medical Research Institute (KEMRI), Nairobi. Antimalarial properties of single and combined extracts were analyzed against Plasmodium berghei in vivo. Cytotoxic properties of the plants were carried out against the vero cell-lines in vitro by the MTT assay. Acute oral toxicity was conducted according to the OECD protocol. Effective concentration (ED50), cytotoxicity concentration (CC50) and median lethal dose (LD50) were derived. The result indicated that the combination of M. senegalensis: W. ugandensis (1:1) had the most antimalarial activity at ED50 of 1.05mg/kg whereas among the single plants W. ugandensis had the highest antimalarial activity (ED50 of 3.3mg/kg). The combinations of C. citriodora: M. senegalensis: W. ugandensis (1:1:1), C. citriodora: M. senegalensis: W. ugandensis (1:0.5:1) and C. citriodora: M. senegalensis: W. ugandensis (0.5:1:0.5) showed cytotoxicity concentration (CC50) of 101.47±3.17 µg/ml, 213.55±3.47 µg/ml and 575.80±31.40 µg/ml respectively. All the plants combinations showed no cytotoxic effects. The synergistic antimalarial properties of combined C. citriodora: M. senegalensis, C. citriodora: W. ugandensis and M. senegalensis: W. ugandensis were confirmed as the extracts showed SFIC indexes of 0.67, 0.83 and 0.28 respectively. All the plant extracts demonstrated LD50 above 2000 mg/kg with no adverse effects hence recognized as safe. This study confirms the safety and antimalarial activities of these plants and justify their use in herbal medicine practices. The results of this study sets the precedence for the development of an antimalarial herbal formulation that is less toxic and more affordable.Keywords: Anti-Malarial Activity, Toxicological Effect, Traditional Medicine
