Abstract: Camelina sativa (L.) Crantz is an ancient oilseed crop. Camelina seed can be used as a food ingredient and raw material for the production of oil. The by-product of camelina oil used as fodder ingredient. But there is no information in Ethiopia about camelina production, so that an experiment was conducted at at Lambuda Hossana area, Southern Ethiopia to investigate the effect of different levels of nitrogen fertilizer on the yield and yield attribute along with different seeding rate of camelina in 2016 cropping year. The treatments were 0, 50, 100 and 150 kg ha-1 and Camelina seeding rate 5, 7.5, 10 and 12.5 kg ha-1. The experiment was laid out in RCBD design with three replications. The result revealed that application of nitrogen has significantly increased the seed yield camelina compared with the control. There was a steady increase in the seed yield of camelina for nitrogen levels from 100 kg ha-1 up to 150 kg ha-1 in the studyarea. Combined analysis of the two treatment factors data showed that still the highest yield was obtained at nitrogen level applied at of 150 kg ha-1 with seeding 10 ha-1. Seeding rate also varied significantly in their performance with respect to yield components and yield ha-1. Accordingly, 10 kg ha-1 performed best relative to the other three seeding rate. It is concluded that there is a significant and positive response of camelina to applied nitrogen and the highest biological and grain yield was obtained at nitrogen level of 150 kg ha-1 with seeding rate of 10kg ha-1. Thus it is recommended that nitrogen fertilizer should be applied in the area to mitigate nitrogen deficiency for enhanced camelina yield.

Abstract: Training is an integral part of agricultural development process. The study was aimed to assess effectiveness of training which was imparted to improve competency of extension functionaries with latest knowledge and skills about latest sorghum (Sorghum bicolor L. Moench) production technologies. In this study descriptive, correlation, regression and t-test were used and all the extension officials participated in the training was included as population (N=36). Data were collected before and after the training course through direct interview and group discussions with help of experts-tested questionnaires. Results revealed that the participants’ training needs were more of commercial-oriented like, value-addition, sweet sorghum, sorghum in rice-fallows and market-led extension. The results of Pearson’s correlation coefficient showed that there was positive significant relation between job experience, trainings exposure to the trainees, level of satisfaction about the training, their age, education and their learning from this training. These variables appeared to be the best fit in the regression model (R2= 0.99075). Majority of them (75%) had moderate level of satisfaction regarding entire training course. More than half of them (53%) had gained the knowledge almost three times more (61-80 knowledge score range) than the pre-training knowledge level (11-40 knowledge score range). The t-test results showed that there was significant difference (at the 0.01 level).

Abstract: This study determined the total length-weight relationships of the four fish species, Inegocia japonica, Gerres decacanthus, Sillago asiatica, and Evynnis cardinalis, belonging to four families. Fishes were collected using commercial trawls from Qinzhou harbor, China. Samples were collected quarterly from March to December 2017. Total length and weight of each specimen were recorded with an accuracy of 0.1cm and 0.1g, respectively. During the sampling period, a total of 111 fish individuals were collected and measured. The allometric coefficient (b) of length-weight relationship varied from 3.08 for Evynnis cardinalis, 3.17 for Inegocia japonica, 3.18 for Sillago asiatica and 3.19 for Gerres decacanthus. Growth was found as isometric for this four fish species.

Abstract: This study was conducted to estimate carbon stock along altitudinal gradient of Sekele-Mariam dry Afromontane forest, North- Western Ethiopia. A systematic random sampling was employed to collect tree/shrub diameter and height, litter and soil data. A total of 60 plots with 50m*50m size each with nested plot (1m*1m) size for litter and soil were laid on the transect line. Diameter at breast height (DBH) of trees/shrubs with DBH ≥ 5cm and height were measured. Carbon stock was estimated using allometric equation and soil organic carbon was analyzed in the laboratory following Walkley Black method. The result of this study revealed that Sekele-Mariam forest had stored a total of 185.71 ton carbon/ha within its aboveground, belowground, litter biomasses and soil. The higher carbon stock in all carbon pools was found at the higher altitudinal range (2395-2460 m a.s.l.). Analysis of variance (ANOVA) result indicated that carbon stock between altitudinal gradient was not significant. The study area had smaller stock of carbon in its biomass and therefore, better forest conservation and management are the best strategy to enhance the carbon stock of the study area.

Abstract: Assessment of the prevailing chicken egg storage materials and length at the rural household in different Agro ecological zone of Eastern Ethiopia were conducted to assess the existing local egg storage facilities and length under the rural farmers. From two zone representing Eastern Ethiopia and the lowland, midland and highland altitude, proportionally 10 districts of 30 rural kebeles were selected using probability proportional to sample size. From each selected rural kebeles, ten farmers were purposely selected. A total of 300 chicken owner were interviewed by structured questionnaire. The collected data were analyzed by SPSS software. The majority of the respondents (98%) in Eastern Ethiopia stored eggs for both marketing and incubation in lowland (86.4%), midland (69.3%) and highland (91.2%) using plastic (28.8%), basket (28.4% and (34.1%) followed by basket (25.4%), pot made of clay/ cow dung (23.9% and 23.8%) along with coffee hulls and dried grass as bedding materials respectively. Mostly, eggs produced at home was used for incubation in lowland (75.9%), midland (76.9%) and highland (73.9%); not experienced for home consumption except for household of better economic status and at the festivity in a year, and to some extent purchased eggs from known neighbor where their qualities were evaluated by shaking and sun candling in lowland (53.8%) and midland (46.7%) and sun candling in highland (51.4%). Hatching eggs were stored more than a week in mid (43.1%) and highland (44%) and about a week in lowlands (48.2%) until the required number of egg was produced for incubation by broody hen. Most of the respondents (78%) were select incubating eggs based on size in lowland (44.9%) and color and size in mid (45.7%) and highland (54.4) preferably large size and white eggs. The common hatching materials used in the area was pot in lowland (61.1%), mid (40%) and highland (53%). Due to suitable weather condition, better hatchability, less disease and parasite infestation and better feed resource availability, most of the respondent (70%) performed incubation during the dry season. Generally, rural poultry producer used different egg storage and hatching materials for different duration, they may influence the quality of eggs for uses that require further investigation to evaluate and recommend the best methods of storage material and duration across different agro ecology and provision of successful training for rural poultry producer; women, on modern egg storage and incubation for improvement of poultry production.
