The study was undertaken in bale zone to assess farmer’s selective breeding objectives, trait preferences, selection criteria and breeding system October 2012 to November 2013. A purposive and multistage sampling technique was applied for selection of 3 district and 9 kebeles. Then 360 households were selected by using simple random sampling techniques after the list of pastoralist having goats was identified. Statistical analysis system version 9.1 was used for analysis of data. Indices, effective population size and rate of inbreeding were calculated on average each respondent holds about 14 goats. Milk production is the main reason of goat keeping in the study area. Appearance is the first rank as selection criteria for male and female in all studies area. About 47.8% of the respondents have their own buck. The main use of breeding buck in the study area was for mating purpose (76.2%). Mean estimate of effective population size and mean rate of inbreeding was 2.43 and 0.21, respectively when a household flock is herded alone and under random mating. Therefore, any breed improvement strategies that are intended to be implemented in the study area and else- where should consider the traditional breeding practices and breeding objectives of the community.

Accelerated soil erosion is a worldwide problem because of its economic and environmental impacts. Enfraz watershed is one of the most erosion-prone watersheds in the highlands of Ethiopia, which received little attention. This study was, therefore, carried out to spatially predict the soil loss rate of the watershed with a Geographic Information System (GIS) and Remote Sensing (RS). Revised Universal Soil Loss Equation (RUSLE) adapted to Ethiopian conditions was used to estimate potential soil losses by utilizing information on rainfall erosivity (R) using interpolation of rainfall data, soil erodibility (K) using soil map, vegetation cover (C) using satellite images, topography (LS) using Digital Elevation Model (DEM) and conservation practices (P ) using satellite images. Based on the analysis, about 92.31% (5914.34 ha) of the watershed was categorized none to slight class which under soil loss tolerance (SLT) values ranging from 5 to 11 tons ha-1 year-1. The remaining 7.68% (492.21 ha) of land was classified under moderate to high class about several times the maximum tolerable soil loss. The total and an average amount of soil loss estimated by RUSLE from the watershed was 30,836.41 ton year-1 and 4.81 tons ha-1year-1, respectively.

A study was conducted to know the current state of development sustainability of the agro-industrial sector in terms of its product diversity, export volume, export value, destination of the product by region and country. A structured questionnaire was prepared to do the random sampling survey and focused group discussion also held with the relevant stakeholder in agro-industrial sphere. The study revealed that in terms of value, the highest exported agro processed product is spices 21.46 million US$ (25%) and in terms of weight, the highest exported agro processed product is drinks (26735 ton). It is investigated that 81% of Bangladesh agro processed product goes to Asian market which value is US$ 70.13 million. In terms of export value, the major destination of Bangladesh agro-processed product is Kingdom of Saudi Arabia(KSA) which amount is 20.2 million US$. In terms of export in weight, the major destination of Bangladesh agro-processed product is India (24372.88 metric ton).

The experiment was conducted to investigate the seed quality of Indian spinach for three months stored at different containers (Plastic pot, polythene bag and cloth bag) during 2013-2014 at Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur. The initial moisture content of the seed was 9.89% with 75.00% germination. However, after two months, the seed had a different range of increased moisture content with reduced germination percentage depending upon the packing materials. Among the three containers, seeds stored at cloth bag absorbed more moisture (14.36%) from surrounding atmosphere followed by the moisture content, 12.67% and 11.50% of polythene bag and airtight plastic pot, respectively. Seeds stored at plastic pot, polythene bag and cloth bag exhibited 65.00, 64.00 and 50.00 per cent germination, respectively. Similarly, the fresh weight and dry weight of seedling and seedling vigor were also decreased. The seeds of plastic pot were good in term of germination capacity, fresh and dry weight and vigor index in comparison to those stored at cloth bag and polythene bag.

A field experiment was conducted at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Ishurdi, Pabna during two consecutive years of 2012-2013 and 2013-2014 to find out the suitable combination of intercropping of chili with sweet gourd for increasing the productivity and economic return. The treatments were T1=100% sweet gourd (2m x 2m) + 40% chili (50cm x 100cm) + 100% recommended fertilizer (RF) of chili, T2=100% sweet gourd (2m x 2m) + 40% chili (50cm x 100cm) + 75% RF of chili, T3=100% sweet gourd (2m x 2m) + 40% chili (50cm x 100cm) + 50% RF of chili, T4=100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 100% RF of chili, T5=100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 75% RF of chili, T6=100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 50% RF of chili, T7=Sole sweet gourd, T8= Sole chili. The experiment was laid out in a randomized complete block design with three replications. Fruit yield was calculated for sweet gourd and chili in ton per hectare considering the whole plot as harvested area. Results revealed that the yield of both sweet gourd and chili significantly affected by plant population and fertilizer dose in the intercropping systems. The highest equivalent yield of sweet gourd (21.21 t ha-1), land equivalent ratio (1.59), gross return (Tk. 318150.00 ha-1), gross margin (Tk. 237935.00 ha-1) and benefit cost ratio (3.97) were obtained from 100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 100% RF of chili (T4). Sole crop of chili (T8) gave the lowest equivalent yield of sweet gourd (7.38 t ha-1), gross return (Tk. 110700.00 ha-1), gross margin (Tk. 37455.00 ha-1) and benefit cost ratio (1.51). Therefore, sweet gourd (100%) and chili (50%) with recommended fertilizer (100%) of chili might be economically profitable for chili with sweet gourd intercropping system.

The chemical composition of four edible plant foods species, three fish species and one prawn were analyzed in Food Chemistry Laboratory of Behbahan Khatam Alanbia University of Technology, Behbahan, Iran in 2014. The analysis of fatty acid and sugars composition were performed by gas liquid chromatography and high performance liquid chromatography, respectively. Protein and lipid content were founded higher in baked and fried in fish S. commersonnianus (74.29%), (20.20%), fish Sphyraena helleri (88.12%) and (17.77%), respectively. Ash content in fish S. commersonnianus varies from 9.80% to 15.34%, and in fish S. helleri from 5.83% to 7.68%. Based on the proximate analysis, it can be calculated that an edible portion of 100 g of studied edible plant foods provides, on average, around 303.9±1.04 kcal. The plant Portulaca neglecta is suitable for high temperature food processes. The macronutrient profile in general revealed that the wild plant foods were with rich sources of protein and carbohydrates, and had low amounts of fat. The highest protein, the lowest fat and energy contents were found in boiled in both fish species; therefore, boiling can be recommended as the best cooking method for healthy diet.
