In order to determine the quality of vermicompost made from market waste mixed with various types of livestock manures (cow dung, goat manure, and donkey manure) during vermicomposting using Eisenia fetida at the same environmental conditions, an experiment was conducted in Asosa town's Asosa soil testing laboratory. Three replications and a fully randomized design were used to set up the experiment. For the manufacture of vermicompost, shallow wood boxes with measurements of 0.4 m in height, 0.6 m in width, and 1 m in length were built. This experiment will be performed in Vermicomposting methods for cow dung, donkey manure, and goat manure mixed with market waste were T1 to T3, and their combination was T4. Three setups for composting (controls) were designated as C1 for cow manure, C2 for donkey dung, C3 for goat dung, and C4 for market waste. At various day intervals, we should measure some physiochemical parameters, such as moisture content, bulk density, ph, EC, CEC, K, Na, Ca, Mg, OC, TN, average P, average K, and average C: N. The findings might indicate that the various kinds of market garbage and livestock manures substantially impact the vermicompost's final nutrient quality. According to this study, vermicomposting is an effective approach for the bioconversion of market waste, donkey dung, goat dung and cow dung to valuable material. v 1. Introduction 1.1. Background of the study Amounts of solid waste accumulate as a result of the rapid growth in population, urbanization, industrialization, and agricultural production. This has caused grave environmental issues. This trash needs to be transformed successfully in order to be disposed of safely. Composting agricultural, urban, and industrial waste, is accomplished. More people are becoming aware of the fact that composting is an environmentally benign procedure that turns a wide range of wastes into beneficial agricultural inputs. Environmental issues are reduced by the vermicomposting process. Compost is a great source of humus and plant nutrients, and its application enhances the soil's biophysical characteristics and level of organic matter. Thus, this technique preserves the soil's quality. Reducing the quantity of organic waste that ends up in landfills, incinerators, and occasionally the ocean is a simple approach to have a good environmental impact. Vermicomposting can be categorized as an alternative, creative technique that is both relatively new and environmentally responsible (Latifah Abd Manaf, et al., 2009). Vermicomposting has been used for many years to improve the soil's physical, chemical, and biological qualities and bring back its original fertility. Vermicomposting offers environmentally acceptable, cost-effective, and sustainable methods for managing trash in an era of quickly rising waste production (Sandeep, et al., 2017 ). Vermicompost's nutritional value is mostly influenced by the kind of substrate (raw materials) and kind of earthworms utilized in the composting process (Manaig Elena M., 2016). Moreover, Eisenia fetida specie is resilient to changes in temperature and moisture. Eisenia fetida is distinguished by its quick rate of growth, early sexual maturation, year-round activity, strong feeding capacity (rapid casting), and wide-ranging reproductive abilities. Because of this, it has been widely used to vermicompost a variety of plant remnants, animal manures, city waste, and sewage sludge (Anil Kumar et al., 2018). Growing amounts of organic waste need to be disposed of, which is turning into a significant issue. Composting is a method for safely disposing of organic waste that is both ecologically friendly and commercially successful. It produces organic fertilizer, a crucial and essential component of organic farming (Thiruneela Kandan and Subbulakshmi, 20 15). Paunch manure is the partially 1 digested feed from the rumen contents of beef at the slaughterhouse. It is comparable to animal dung in properties and is a great material for vermi-worm composting (Ron Fleming et. al, 2004). Paunch manure can be composted for agricultural sustainability and as a safe way to dispose of it or use it to improve the environment (Ron Fleming et. al, 2004). The purpose of this experiment is to investigate the quality and nutritional content of bovine paunch manure vermicompost processed by Eisenia fetida based on the aforementioned facts. In order to make vermicompost, market waste from Asosa Town Market will be used, along with cow dung, donkey manure, and goat manure. 1.2. Statement of the problem The disposal of ever-increasing amounts of organic wastes is becoming a serious problem. The hygienic disposal of organic wastes by composting is an environmentally sound and economically viable technology resulting in the production of organic fertilizer which is a basic and valuable input in organic farming (Thiruneela Kandan and Subbulakshmi, 20 15). The market waste produced from market form a major component of putrefying organic waste that end up in landfill sites or disposed off in to roadsides and waterways in many developing countries. The main problems encountered with market waste composting are its high moisture content, need of bulking substrate and constituents unacceptable for worms. The aim of the experiment will improve the quality of the final vermicompost by mixing the different types of livestock manure with market waste, and taking constant care with moisture management, constituents of the waste, the ratio of carbon and nitrogen that affect vermicomposting. 1.3. Objective 1.3.1. General objective To determine the Nutrient Quality of vermicompost Prepared from market waste mixed with different types of livestock manure. To improve waste management of market waste. 2 1.3.2. Specific objective To know the chemical composition of vermicompost produced from market waste mixed with different types of livestock manure. To compare the efficiency of market waste degradation among different types of livestock manure To provide wastes as environmentally friend and alternative raw materials for vermicomposting to produce organic fertilizer. 1.4. Scope This paper focuses on the hygienic disposal of organic wastes by vermicomposting. Vermicomposting is an environmentally sound and economically viable technology which results in production of organic fertilizer from market waste mixed with different types of livestock manures (cow dung, goat manure and donkey manure). The experiment will have conducted at Asosa town in Asosa soil testing laboratory to identify the quality of vermicompost produced under same environmental conditions using Eisenia fetida earthworm species. The aim of the experiment will improve the quality of the final vermicompost by mixing the different types of livestock manure with market waste 3 2. Literature Review More nutrients are readily available in the various organic wastes, such as water hyacinth, press mud, and market waste. Yet, the recycling potential of these wastes is underutilized. After composting, this waste has the potential to significantly boost crop output. The main goal of the process of composting is to use solid waste of both animal and plant origin in the growth of crops. Composting's primary goal is to maximize original carbon and other nutrient conversion while yet allowing for adequate mineralization. The use of earthworms is a possible source for the decomposition of any sort of organic waste, in addition to the use of cellulolytic and other microbial cultures for accelerating decomposition and enriching compost. According to (Karthikeyan et al., 2007), the vermicomposting technique will efficiently turn market garbage into enriched manure in a way that is safe for the environment and will also generate income from the waste quickly. earthworms are used to break down organic waste, such as sewage sludge, animal manure, crop waste, and industrial waste, to create vermicompost (Giraddi et al., 2002). The availability of NPK and the microbial population in vermicompost will both significantly increase (Jambhekar, 1992). There is a dearth of information and experimental data regarding the composting of market trash, as well as the function of microbial inoculants and earthworms in this process. In light of this, an inquiry into the composting of market trash was conducted utilizing earthworms, Pleurotus, and Coprophilus bacteria linked with cow dung as agents for bioconversion. Vermicomposts are stabilized organic soil supplements that are made by a non-thermophilic process in which earthworms and microorganisms work together to break down organic matter in an aerobic environment. The nutrients are liberated and changed into soluble and usable forms during vermicomposting. In 2001, Ndegwa and Thompson Sewage sludges have been used in prior experiments to feed various organic wastes to earthworm species (Benitez et al. 1999; Delgado et al. 1995; Diaz-Burgos et al. 1992); paper mill industrial sludge; etc. Pig waste (Chan, L.P.S. & Griffiths, D.A. (1988); Butt, K.R. (1993); water hyacinth (Reeh, U. (1992) Paper waste, Gajalakshmi, S. et al., 2001 Brewery yeast: Gajalakshmi, S. et al., 2002 Crop residues, Butt, K.R. (1993) Cow slurry, Bansal, S. & Kapoor, K.K. Cow dung, Hand, P. et al. (1988). Sludge from the vine fruit industry, by Mitchell, A. In 1993, Atharasopoulous, N., rice husks, and mango leaves S.C. Talashilkar and others (1999) likewise activated sludge Textile mill sludge, Hartenstein, R. 4 & Hartenstein, F. (1981). Garg, V.K., and Kaushik, P. (2003), etc. According to Loh T.C. et al. (2004), cattle manure produced more Eisenia foetida cocoons and gained more biomass than goat waste. According to Kale, R.D. et al. (1982), Perionyx excavatus has the ability to vermicompost a variety of wastes (sheep dung, cow dung, biogas sludge and poultry manure and sand as control). Cow and horse manure were readily taken by the worms. Three or four days after it was added, sheep feces were eaten. By releasing nitrate and phosphate into the air, groundwater, and surface, as well as ammonia, carbon dioxide, and hydrogen sulfide gas, manures seriously harm the environment (Ahsan et al., 2013 and 2014; Lee et al., 2009; Rahman et al., 2008; Sarker et al., 2009; Won et al., 2016). In addition to this, livestock manures may contain diseases that have created major problems with public health (Alam et al., 2013; Rahman et al., 2013; Runge et al., 2007). Moreover, manure biomass has the potential to be a source of the greenhouse gases that cause global warming. Manure that is dumped carelessly causes a number of issues, such as an unpleasant stench, flies and beetles, and road damage from excessive traffic. If adequate recycling techniques are used, these cattle manures could be a significant resource; otherwise, they constitute a burden to the environment (Al Amin et al., 2020; Krishan et al., 2014; Punde and Ganorkar, 2012; Rahman et al., 2020a and 2020b; Rana et al., 2020). Earthworms and aerobic bacteria work together to limit the danger of environmental pollution and stabilize nutrients during the vermicomposting process from waste biomasses. Vermicomposting is a process that involves changing solid biomasses in earthworms' guts in a physical, chemical, and biological manner (Atiyeh et al, 2001). 5 3. Materials and Methods 3.1. Description of the composting site The Asosa zone of the Benshangul Gumeez Regional State is home to the Asosa Soil Laboratory's experimental field. Moreover, it is situated at 10°04′N latitude and 34°31′E longitude. The elevation is approximately 1,570 meters. The climate of Asosa is tropical wet and dry or savanna. The average yearly temperature in the district is 27.27 °C (81.09 °F), and there are normally 161.2 wet days per year, accounting for 44.16 percent of all days with precipitation. 3.2. Design of experiment The experiment would have been carried out in two stages, the first of which would have involved the creation of vermicompost from market garbage combined with various forms of livestock manure (cow dung, goat manure, and donkey manure), and the second the physiochemical analysis of those vermicomposts. To reduce experimental mistakes, the experiment will been set up with a fully randomized design and three replications. The treatments included three different kinds of livestock dungs (cow dung, goat manure, and donkey manure), each of which will be combined with market garbage in order to achieve the experiment's goals. We will conduct these tests in three composting setups (controls), denoted as C1 for cow dung, C2 for donkey dung, C3 for goat dung, and C4 for market waste. Vermicomposting processes for cow dung, donkey dung, and goat dung mixed with market waste would designated as T1 to T3, and their combination will have designated as T4. For the manufacture of vermicompost, shallow wood boxes with measurements of 0.4 m in height, 0.6 m in width, and 1 m in length will built. In this experiment, a total of 24 shallow wood vermicomposting boxes will be used. 3.3. Collection of raw materials and preparation of vermicomposting box Farmers would collect the manure and dung from their livestock. Before establishing the compost, red worms (Eisenia fetida) for vermicomposting will previously be held in suitable breeding conditions in the soil laboratory at Asosa. Twenty-four vermicomposting Vermicompost was created in shallow wood boxes. For each wood box used in the experiment, 30 kg of market waste and 10 kg of each type of manure will be gathered. 6 3.4. Vermicomposting process For the manufacture of vermicompost, shallow wood boxes with measurements of 0.4 m in height, 0.6 m in width, and 1 m in length will be built. First, four treatments were created in triplicates using a total of 100 kg of substrates, 70% (seven portions) of market waste, 30% (three potions) of dungs, and 30% (cow dung 10% (one portions), goat dung 10% (one portions), and donkey dung 10% (one portions) for the combination of dungs. These treatments were added to various shallow wood boxes and spaced apart by about 0.5 meters. Then, each Small wood box received roughly 500g of earthworms. The manure's initial moisture level was kept between 70 and 75 percent since it facilitates the worms' simple mobility. Moisture level was checked in the vermicomposting box on a regular basis and kept the box on a dry place. The experiment was conducted under a shed to avoid direct sunlight and rain. 3.5.
