Abstract: An experiment was conducted to identify better performing food barley cultivar at Amuru District of Horo Guduru Wollega Zone of Oromia National Regional State of Ethiopia in 2016 main cropping season. The experiment was laid down in a Randomized Complete Block Design (RCBD) with three replications. The treatments were factorial combination of four weeding frequencies (weedy check, one time weeding, two times weeding and three times weeding) and five food barley cultivars (HB 1307, CROSS 41/98, GOBE, EH1493 and Local). Yield and yield components of barley including spike length, thousand kernel weight, grain yield and biological yield were significantly influenced by main effect of variety and weeding frequency. However, number of productive tillers, kernels per spike, and harvest index were significantly influenced by interaction effect of variety and weeding frequency. HB 1307 variety gave significantly higher grain yield (1292 kgha 1) than the other four barley cultivars. Three times weeded treatment gave significantly higher grain yield (1422kgha 1) followed by two times weeded (1000kgha 1), one times weeded (644 kgha 1) and weedy check (511kgha 1). Three times weeding of barley is the optimal weeding frequency and use of HB 1307 variety is better to increases grain yield in the area. However, need to be developing site specific varieties to the study area as the yield of improved varieties less performed.

Abstract: Bush thinning or clearing rangeland management practice in Borana rangelands considered to have a high potential to improve rangeland productivities and soil conditions, yet few studies have quantified the impacts of bush management on herbaceous plants species diversity, biomass and soil Organic Carbon and Nitrogen contents. This study was conducted in Yaballo (Hara-woyu Kebele) and Taltale (Sarite kebele) Woreda of Borana zone, to evaluate the impacts of bush management (thinning) on herbaceous plant species composition, diversity, biomass and some selected soil physicochemical properties. Data were collected from bush thinned and bush encroached rangeland management classes at both sites. Sampling plots were placed systematically along the geographic gradient in both of the rangeland management classes at both study sites. Within all plots, herbaceous plants were identified and clipped to the ground, collected and oven-dried to determine biomass. Herbaceous plant species, diversity, biomass and soil organic carbon contents and soil carbon stock were higher under Bush managed (thinned) class compared to bush encroached. However, bush management (thinning) have not shown considerable effects on soil bulk density, pH, nitrogen contents and total nitrogen stock. Thus, understory vegetation and soil organic carbon were influenced by the presence of thinning, but soil bulk density, pH, nitrogen contents were not influenced by thinning in this study. Generally, bush management (thinning) increased the rangeland condition, however; the management is not sustainable in case the thinning practice is not followed recommended procedures because most of the encroacher species are sprout more densely within a short time.

Abstract: The city of Kinshasa, capital of the Democratic Republic of Congo, is currently experiencing unprecedented urban and peri-urban development, which is reflected in the degradation and loss of vegetation cover. There is a real need to conduct sociological studies on trees to help leaders in their decision-making. This research aims to analyze the perception of the population on the role of trees in the peri-urban area of the city of Kinshasa. The data were collected through a survey conducted in the Kinkole neighborhood, located in the eastern part of the city. A total of 321 residential plots were sampled between September and November 2017 to conduct semi-structured individual interviews. After compilation, the collected information was synchronized and then analyzed using Excel software to produce relative and absolute frequencies. The results obtained show that trees are primarily planted for economic, food, shade, and pharmacopoeia needs. The trees planted in the plots are mostly fruit trees, of which three species alone account for more than two-thirds of the planting. These are the mango tree (Mangifera indica) with 31.3% of trees planted, followed by the avocado tree (Persea americana) representing 31.1% of the plantation and then the safflower tree (Dacryodes edulis) representing 25.7%. The seedlings of these trees come mainly from consumed seeds. However, nearly half of the residents feel that they do not need to add other trees to their plots due to lack of space or property rights. These results reveal the urgency of promoting urban and peri-urban forestry through the development of a policy and strategies for the adequate management of peri-urban spaces in the city of Kinshasa. This is in order to improve the quality of life of the human population in order to face the current challenges related to the effects of climate change in urban and peri-urban areas.

Abstract: It is a natural tendency of human to look them attractive and younger. For this purpose, they largely depend on several skin care products including herbal as well as chemical ones. But chemical ones have a variety of side effects which are not acceptable to beauty conscious people. That’s why, they are highly intended to use herbal ingredients as these are perfectly safe. Nowadays, essential oils are the most popular ingredients used for daily skin care activities. They have become good alternative and complementary therapies with mainstream cosmetic products and have gained the momentum. Essential oils (EOs) are mainly the volatile aromatic compounds of herbs and spices and these oils are generally extracted from the flowers, barks, seeds, stem, leaves, roots, fruits and other parts of the plant. Nowadays, essential oils are being randomly incorporated in variety of skin care products for their different biological activities such as antimicrobial, anti-inflammatory and antioxidative properties and hence protect skin from environmental damages and help to cure certain skin ailments for keeping skin youthful, healthy, fresh. This review paper focuses on some essential oils which have extreme skin benefits and play a great role to deliver a beautiful as well as charming skin.

Abstract: Determination of appropriate row spacing and phosphorus rate of mung bean can increase its productivity. Therefore, a field experiment was conducted at Fedis Agricultural Research Center during main growing season to evaluate the effect of phosphorus rate and row spacing on yield and yield related traits of mung bean. Factorial combinations of four phosphorus rate (0, 23, 46, 69 kg P2O5 ha-1) and three row spacing (20, 30, and 40 cm) laid out in RCBD with three replications. A total of 12 treatments and Borda variety was used for the experiment. The results revealed that there were significant (P<0.05) differences for plant height, total and effective number of nodule plant-1, pod plant-1, thousand grain weight, dry biomass yield and grain yield due to phosphorus application. Branch per plant, pod per plant, pod length and dry biomass yield were significantly (P<0.05) affected due to row spacing. The highest Thousand Grain Weight (30.18 g) was obtained from the application of 46 kg P2O5 ha-1 while the lowest (28.27 g) was obtained from 0 kg P2O5 ha-1. The highest grain yield (961.6 kg ha-1) was achieved from 46 kg P2O5 ha-1 while the lowest (766.7 kg ha-1) was from 0 P2O5. In conclusion, the application of 46 kg P2O5 ha-1 and 30 cm row spacing recorded highest grain yield with highest economic returns (14123.78 ETB ha-1). Based on grain yield and economic return, combination of 46 kg P2O5 ha-1 and 30 cm row spacing was recommended for the study area and similar agro-ecology.
