ABSTRACT: The purpose of this study was to determine the ability of soil bacterial isolates from Mount Jayawijaya, Papua to degrade polyethylene terephthalate synthetic plastics. Research methods used were macroscopic, microscopic and biochemical characterization of bacterial isolates, polyethylene terephthalate synthetic plastics biodegradation test usingdishakermethod (Shake Flask Experiment) was performed for 30 days andsampling of plastic weight reduction was done once a week. The characterization result of nine bacterial isolates were Gram positive bacteria and the identification results by the biochemical test showed seven different bacterial species, namely: Bacillus sp. 1, Bacillus sp. 2, Bacillus sp. 3, Bacillus sp. 4, Bacillus sp. 5, Bacillus sp. 6 and Bacillus sp. 7. The result of biodegradation testshowed six isolates with ability to degrade synthetic plastic while 1 isolate(ITP 6.2) does not have the ability to degrade synthetic plastics. Bacteria isolate that have a high ability to degrade synthetic plastic was ITP 3.4 (3.41%).

ABSTRACT: A field experiment was conducted at the experimental farm of Agricultural Training and Education Centre (ATEC) in Gu' season, 2019 (April-June), Afgoi, Somalia. The seeds of the single maize variety(Somtux variety) were used in this experiment. Seeds were sown on 28 April with spacing of 75x30cm. The experiment was laid out in a randomized completely block design (RCBD) with four replications. Weed control methods viz. Post emergence herbicide (NICO SULFURON @2 L ha-1), one hand weeding, twohand weeding, threehand weeding, four hand weeding and no weeding (Control) were allocated to plots randomly and the gross plot size was 7x6.4m. Three sample plants were randomly selected from each plot and marked with the tag for recording plant characters. Data on Plant stand....

ABSTRACT: Sweet corn is an attractive crop due to its high yield per unit area, short vegetation period and a good plant in crop rotation. In order to determine the suitable sweet corn varieties for Erzurum region, this research was carried out in Ataturk University Plant Production Application and Research Centre, during the 2017 and 2018 cropping seasons. Randomized complete block design was used; some traits of the varieties related to growth, yield and quality was investigated. A significant difference was determined among the varieties in terms of the investigated traits. In terms of days to silking (SD), the mean values ranged between 76.17-90.67 days, days to maturity (MD) was between 105.67-120.17 days, plant height (PH) was between 169.97-215.97 cm, number of tillers per plant (NT/P) was between 0.13-1.50, number of leaves per plant (NL/P) was between 8.92-10.95. The number of ears....

ABSTRACT: Formal, one-off, cross-sectional survey conducted in twenty villages in four departments south of Maradi (Niger) involved 197 people (78.7% women, 21.3% men), in order to determine the socio-cultural and practical roles of Red and Black goat farming. Respondents were Hausa (94.41%), married (91.88%), aged 45.42 ± 14.67 years and practicing Islam (100%). The activities were: agriculture (43.7%), small business (34.0%), livestock (21.3%) and manual labor (1%). Households reared cattle, sheep, goats, donkeys, horses, camels and poultry, associated. Herdcomposition per capita depended on the farmer. Animalhousing was made of local materials, thorny enclosures or without.....

ABSTRACT: Oreochromisniloticus fingerlings were fed diets containing 25, 50, 75, 100% levels of cassava peel meal as replacement for maize and a control, for eight weeks.O. niloticusfingerlings were stocked ten (10)for each tank. The fingerlings were fed twice daily by 8am and 4pm at 5% body weight. The fingerlings were weighed weekly to determine weight. Fish fed diet25% gained a mean weightof 1.79±0.02 for the period of the experiment. The poorest performance was from diet E (100%). The fingerlings fed diet E gained a mean weight of 1.26±0.01 during the experiment. The various growth indices of specific growth rate, feed conversion ratio and feed efficiency ratio show that diet 25% has SGR of 1.66±0.02, FCR of 3.04±0.04 and FCE of 32.93±0.48, diet 100% gave the SGR of 1.30±0.00, FCR 3.68±0.02 and FCE of 27.20±0.13. Water quality parameters of dissolved oxygen, pH, temperature, electrical conductivity and total dissolved solids were monitored.

ABSTRACT: The aim of this research work was to explore the effect of different levels of orange peel extract as a natural antioxidant and antimicrobial agent on fresh and preserved beef. The beef were subjected to four treatment with different level of orange peel extract (T0 = fresh raw beef; T1 = 0.2% orange peel extract, T2 = 0.3% orange peel extract and T3 = 0.4% orange peel extract) and carried out to evaluate sensory, proximate components, physicochemical quality, biochemical quality and microbiological assessment as natural antioxidant and antimicrobial agent for maintaining beef qualities and the shelf-life of beef for 0, 15th, 30th and 60th day of storage period. Color, flavor, tenderness, juiciness, overall acceptability at different levels of orange peel extract were almost similar.....
