And this study used qualitative and quantitative methodologies. A multi-stage sampling method was used to select 400 sample sizes. Descriptive statistics method was used to find out modes of agricultural market imperfections, and Tobit model was employed to capture the effects of agricultural market imperfections on multidimensional rural poverty. And the multidimensional poverty index (MPI) technique was employed to measure the severity of multidimensional rural poverty. Apart from what they have traditionally done by themselves, about 23% of people lack knowledge about how to produce and where to sell using modernized information. The Tobit model was also employed to figure out how market imperfections affected multidimensional poverty in the study area. This study showed that 43% of farmers transport their goods by carrying them on their shoulders to the market. For farmers with asymmetric information, the multidimensional poverty index (MPI) is expected to have a value of 0.4354 higher than those with symmetric information. Furthermore, the Tobit model’s findings showed that labor, improved seed, farm size, cooperative membership, and commercialization experience significantly negatively impacted multidimensional rural poverty. And asymmetric information, transaction cost, and infrastructure inaccessibility had a statistically significant and positive impact on multidimensional poverty. Hence, improving input usage and creating access to agricultural market information is a foundation for reducing multidimensional rural poverty.","PeriodicalId":10521,"journal":{"name":"Cogent Food & Agriculture","volume":"117 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135725217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-four male lambs (initial body weight (BW) = 16.82 ± 0.998 kg; age = 70 ± 1.25 days) were randomly assigned to two isonitrogenous diets; OL at 0 (CON) or 150 (OL150) g/kg of dietary dry matter (DM). Diets were fed ad libitum for a period of 60 days after 7 days of adaptation. Feed intake and refusals were recorded daily. Body weights were recorded at the beginning of the study and at biweekly intervals thereafter. Intake of DM and crude protein was similar (P ≥ 0.05) between the two diets. Feeding OL decreased (P ≤ 0.01) intake of neutral detergent fiber and acid detergent fiber whereas it increased (P = 0.001) intake of ether extract compared with the CON diet. No differences (P ≥ 0.05) were observed in the final BW, average daily gain, and total gain between diets. However, the cost of gain was lower (P = 0.05) in lambs fed the OL diet versus the CON diet. None of the carcass characteristics nor meat quality parameters differed between the two diets. In summary, feeding olive leaves at 150 g/kg did not influence growth performance and carcass characteristics and meat quality but improved the economic value of using such products in diets of growing lambs. In addition, the use of this product has a positive impact on reducing environmental pollution.","PeriodicalId":10521,"journal":{"name":"Cogent Food & Agriculture","volume":"34 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135819622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By interfering with natural processes, it deteriorates soil properties and endangers agricultural production. Different soil and water conservation (SWC) practices have been implemented in many regions of Ethiopia to combat it. Reviewing successful soil conservation methods in Ethiopia and their impacts on soil properties, agricultural productivity, and technical soil conservation quality are the main goals of this paper. Data were gathered from a range of sources, including publications on soil conservation, conferences, thesis works, and periodicals. SWC practices had either a positive or negative impact on the soil’s physicochemical characteristics and crop productivity. Under both biological and integrated SWC practices, the mean values of pH, TN, AVP, OM, and CEC were higher on treated farmland than on untreated farmland. Under all SWC practices, the average bulk density was higher on acreage that had not been treated than it had been. By effectively using SWC technology and integrating physical and biological measures, the technique for repairing soil physicochemical properties, reducing soil erosion, and enhancing agricultural productivity would be improved. In order to improve technical quality, soil quality, crop yields, and society’s means of subsistence, it is therefore possible to advise that the layout of conservation measures, intensive capacity building about the layout of structures, and standard procedure be followed.","PeriodicalId":10521,"journal":{"name":"Cogent Food & Agriculture","volume":"32 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135819328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A large body of empirical literature shows how different technologies and improved practices can affect welfare indicators. However, rigorous evidence on the food security and nutritional implications of these technologies remains scarce in general and particularly in developing regions such as sub-Saharan Africa. This study uses panel data and adopts a fixed-effects approach as the main analysis method. Propensity score matching and endogenous treatment effects techniques are also used to test robustness and reduce selection bias in the estimation process. Thus, this study examines the relationship between adoption and nutrition, which has received little attention in most previous studies, and evaluates the impacts of three improved agricultural technologies (row planting, high-yielding seed varieties, and chemical fertilizers) on household food security and child nutrition. The results of the study show that the adoption of these technologies had a significant impact on both per capita consumption expenditure and child nutrition. In addition, the results of the differential impact analysis confirmed that impacts differed across the different segments of the households (quartiles based on area under improved technology and gender). We, thus, recommend the use of advanced agricultural technologies in combination (multiple types) rather than as separate technologies, and relevant institutions should promote the combination of advanced agricultural technologies, and the need for continued and large-scale public and private investment in the sector to address major development challenges. Finally, we note that the results from the current study have a broad and generic value that can be applied to a range of related cases in other developing countries.","PeriodicalId":10521,"journal":{"name":"Cogent Food & Agriculture","volume":"28 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135973338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These outbreaks pose significant threats to food security and rural livelihoods, yet there is a lack of understanding of the factors affecting effective cattle disease management among smallholder farmers. In this paper, we determine the factors affecting effective cattle disease management in Mutare rural district, Zimbabwe. We quantify the economic losses associated with cattle diseases which we use as a proxy for effective cattle management. Multiple linear regression was used to analyse the data. Six wards were chosen at random among 36 wards in the district, and primary data was gathered from 90 randomly selected farmers. The results showed that cattle diseases cause significant losses in the rural Mutare district, with an average loss of US$ 1 288.87 per farmer during the two years under study. The level of education of the household head, access to an animal health officer, and training on cattle diseases are significant variables in reducing economic losses due to cattle diseases at 5% while formal credit access was found to be statistically significant at 1% significance level. To lessen the losses brought on by cattle diseases, we recommend the government raise the number of animal health officers, strengthen training programs on preventing and controlling cattle diseases, invest in the development of a comprehensive disease-reporting network, and the creation of policies that incentivize banks to lend money to farmers.","PeriodicalId":10521,"journal":{"name":"Cogent Food & Agriculture","volume":"21 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135973189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
