Ayele, Aregagn Petrous","doi":"10.59122/134d203","DOIUrl":"https://doi.org/10.59122/134d203","url":null,"abstract":"Traditional agriculture has had negative effects for many years, including low crop productivity, food insecurity, and malnutrition. The main objective of this study was to compare the effects of conservation tillage with conventional and traditional tillages on maize yield and sandy soil properties at Arba Minch Zuria and Gacho Baba Woredas of Gamo Zone. This study revealed that most of the soil properties are influenced by soil management practices. The soil fertility elements such as OC, TN, and CEC were found to be low in studied soils before and after planting. “Below Optimum” (very low, low, medium) levels of nutrients such as TN, OC/OM, exchangeable bases, CEC and PBS were found to be low in studied soils; considered deficient and limit crop yield. These limiting nutrients do not allow the full expression of other nutrients that are available in optimum amounts. Multi-nutrient deficiencies in soils have led to a decline in productivity and deterioration in the quantity and quality of the produce. “Optimum” (sufficient, adequate, proportional) nutrient levels are considered adequate and will probably not limit crop growth. “Above Optimum” (high, very high, and excessive) levels of nutrients were considered more than adequate and will not limit crop yield. P2O5 and, K2O are above high and not considered as a yield limiting mineral elements. CA fields increased maize yield by 39%, and 59% as compared to the CO and TR Fields in the year2019, respectively). Similarly, CA fields increased maize yield by 54%, and 62% as compared to the CO and TR in the year 2020, respectively. Therefore, it might be advised to use management techniques that improve soil nitrogen availability. Rotation and intercropping of suitable leguminous species that contribute N to the system are also necessary, but the soils in the study area need to be Rhizobium-host-required before any specific recommendations can be made.","PeriodicalId":353130,"journal":{"name":"OMO International Journal of Sciences","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129724220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its production is limited by many factors. Of these, less fertile soil is predominant. In the region, the rational use of fertilizers has not been studied. In addition, the type of fertilizer required and the optimal fertilizer rate for the area have not been quantified. Field trials were carried out in Derashe district to evaluate the ratio of compound fertilizers to improve sorghum yield. The treatments were laid out in a Randomized Complete Block Design, with three replications, using Melkam sorghum variety. The experiment had thirteen treatments consisting of control (no fertilizer), four different types of blended fertilizers (NPS, NPSB, NPSZn and NPSZnB) each with three rates. Our analysis show that the highest grain yield was recorded from the plot that receive 225 kg∙ha-1 NPSZnB + 117 kg∙ha-1 urea in the first year, In the second year, the highest yield was recorded from the plot that received 150 kg∙ha-1 NPS + 88 kg∙ha-1 urea. In both years, the lowest grain yield wasmeasured from the plots treated with no fertilizer (control). The marginal analysis showed that application of 112 kg∙ha-1 NPSZnB + 59 kg∙ha-1 urea is economically the most profitable than the other treatments. Based on our findings, it is recommended to apply 112 kg∙ha-1 NPSZnB + 59 kg∙ha-1 urea for the profitable production of Melkam sorghum variety in the study area.","PeriodicalId":353130,"journal":{"name":"OMO International Journal of Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116025867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were gathered by field observations, key informant interviews, and a standardized questionnaire. With 149 responses, the district was divided into three agro-ecologies. Using a technique called probability proportional to size-sampling, the number of responders was calculated. Lowland,mid-altitude, and highland regions all had average land sizes of 1.67, 0.27, and 1.38 ha, respectively. The research district's entire livestock population was calculated to be 134,948.84 TLU. Cattle made up 83.23% of this, followed by goats 6.19%, donkeys 5.09%, sheep 3.51%, chickens 1.19%, mules 0.53%, horses 0.18 percent, and camels 0.002% of the district's total TLU of the animal population. There were 9.5 heads of local and crossbred cows in each household'saverage herd. Dairy cattle in the study locations primarily ate natural pasture, crop residues, crop aftershock grazing, standing hay, maize that had been thinned, and unconventional feeds (Cheka atella and Areke atella). Grazing land produced 97.75 tons of dry matter per year, crop leftovers 827.21 tons, conventional feeds 264.78 tons, fodder trees and shrubs 1.29 tons, crop aftermath grazing 110 tons, concentrates 0.5 tons, and forest land 30.54 tons. A total TLU value of 1693.5 was obtained by analyzing the overall feed balance in terms of DM yield annually. The present TLU units with a negative balance of 2513.16 tons demand about 3861.85 tons of DM annually. There was a deficit of 140 tons in the total CP produced and needed for the TLU, which came to 477.18 and 617.72 CP tons, respectively. Overall metabolizable energy (ME) produced and needed for the TLU were 25,739.3 and 73683.72 tons MJ, respectively, with a negative balance of 47,944.42 tons MJ of ME. Free grazing, stall feeding, and tethering were the three main feeding methods used in the research locations. Lack of feed, a lack of grazing pasture, subpar extension services, and a lack ofwater were the main obstacles and issues for the development of dairy cattle. Possibilities for increasing dairy feed output include favorable meteorological conditions, cereal crop productivity, and road access. The growth of forage, the collecting and storage of crop leftovers under sheds, the conservation of forage, particularly hay and silage, and the facilitation of feed selling mechanisms in local market areas could all help ease feed scarcity issues.","PeriodicalId":353130,"journal":{"name":"OMO International Journal of Sciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128496596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Primary and secondary data sources and field observations, key informants interview, focus group discussions and individual interview was employed to generate data. The survey data was stratified into districts, coded and analyzed usingthe Statistical Package for Social Sciences (SPSS version 20) windows 10 and general linear model procedure were used to analyze data . Statistical variation of categorical data (perception data) was tested by means of cross tabulation. In study districts, the palatable and perennial fodder trees were Erythrina brucei, Arundinaria alpine, Ficus sur, Dombya torrida and Hagenia abyssinica were supported major feeds for livestock. The major opportunity related to livestock feed productionin study districts was presence of different feed resource types, distinctive agro-ecologies and accessible of crop residues, but the major constraints related to livestock feed production were land scarcity, shortage of dry season forages and land degradation due to erosion. Minimize livestock number, conserving optional feeds and purchasing optional feeds were major copying strategies of feed resources in study districts. The overall mean of feed supply in terms of DM yield per year to TLU was found to be 5.782tons of DM /Hh/ annual with negative feed balance of 5.47tons. Based on the findings of the present study, low productivity of livestock in Bonke, Dita and Mirab Abaya districts is clearly associated with the meager availability of feed resources. Hence, in order to alleviate these problems, alternative feed production technologies should be undertaken, such as, farmers should practice forage development on their own crop land and collect crop residues during crop harvesting times and conserve it under shed, the nutritive value of different types of fodder trees and shrubs should be further determined in the future, feed storage methods, particularly hay and silage during an excess of feed resources available should be practiced.","PeriodicalId":353130,"journal":{"name":"OMO International Journal of Sciences","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125511723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For maintaining a good dairy enterprise and have steady income, it is essential to have the animals with good reproductive status with balanced nutrients in their diet. Most dairy research tends to focus on protein and energy needs, and trace minerals are often overlooked. Though, different forms of organicminerals differ in their solubility, availability and effect on animal performance and benefits appear to be more promising in the non-ruminants than in the ruminants, there is almost a consensus that organic trace minerals have higher bioavailability resulting in better animal performance, health, production immune response and stress alleviation than their inorganic salts. High yielding dairy cow requires quality feed with organic minerals and hence the bioavailability of these minerals form an essential component in the production system. Organic trace minerals consist of the same trace minerals being chelated, complexed or covalently bonded to amino acids, analogues, proteins or organic acids in a way that allows for increased absorption in the animal. In this context, organic (chelated) trace minerals can be a better solution compared to other feeding inventions. It is concluded that minerals from organic sources have higher bioavailability than inorganic sources. In dairy animals, majority of factors like nutrient intake, physiological status, manage mental and climatic conditions affect fertility of the animal. The main factor affectingthe reproductive potential in different developing regions including Ethiopia is nutritional status of cows that too trace minerals. So further research with organic trace minerals is needed to: 1) better define conditions where performance or health responses may be expected, 2) define the optimal level of organic trace mineral(s) that should be added to the diet, 3) determine if responses observed are of a magnitude necessary to justify the cost, and 4) determine the mode of action whereby to improve the reproductive efficiency dairy cows.","PeriodicalId":353130,"journal":{"name":"OMO International Journal of Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116782413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
