Abstract: Onion is one of the important vegetable crops produced in many home gardens and in some extent commercially in different parts of Ethiopia. Therefore, this experiment was conducted at Alage Central Rift Valley of Ethiopia with the objectives of assessing the growth, yield, and quality response of onion to the variable rates of poultry manure and mineral nitrogen fertilizer. The experiment comprising of three nitrogen levels (0, 46, and 92 kg ha-1) and four levels of poultry manure (0, 5, 10, and 15 t ha-1) were laid out in a randomized complete block design with three replications. The result indicated that leaf length, leaf number, days to maturity, bulb length, and bulb dry matter content were significantly influenced by main factors. Application of poultry manure at the rate of 15 t ha-1 recorded the highest total bulb yield (63.33 t ha-1) and marketable bulb yield (62.52 t ha-1), but statistically, there was no significant difference between 15t ha-1 and 10t ha-1 poultry manure application. The results of the partial budget analysis showed that 15 t ha-1 poultry manure application gave the highest marginal rate of returns. Since the highest bulb yield and maximum marginal rate of returns are obtained at 15 t ha-1 poultry manure application, this rate can be recommended for onion production in the researched area, and areas having similar agro-ecologies. However, as the research is conducted for a single season and location, repeating the experiment over location and year will be required to give a conclusive recommendation.

Abstract: This study was conducted in Organic and Akseker Export abattoirs of Modjo district of Eastern Shoa zone of central Ethiopia with the aim of phenotypic evaluations of indigenous goats exportable to Akseker and Organic Export abattoirs of Modjo modern export abattoirs aimed at improving the community-based breeding strategies of indigenous goats and their phenotypic traits exported to export abattoirs for meat consumption. A total of 200 goats from both export abattoirs were sampled randomly for phenotypic evaluations. Length, weight, height, and heart girth of the animal were measured for each goat exported to both abattoirs. The results show that significantly (P<0.05) presence of clear phenotypic variations between and within these indigenous goats exportable to Akseker export abattoirs whereas heart girth significantly (P<0.05) increased by 20.271 (CM) the length, weight (KG) and height increases by (0.163 CM), (0.256 KG) and (0.479 CM) respectively. However, there is no evidence showing any association with sex, age, body condition, and age of animals. The examined phenotypic parameters of goats exported to organic export abattoirs were measured but there is no-showed significant (P-value >0.05) association between and within heart girth, height, and body length of the goats except for the high level of significant variations (P<0.05) between hearth girth on body weights which says when heart girth increases by 7.26 (CM) centimeters, the body weight significantly with P value (0.001) increases by 1.92 (Kg) kilograms. In conclusion, to sustainably utilize these goat populations the production constraints should be solved and selective community-based breeding strategies should be designed and well implemented.
