This article is focused on studying the causes of agricultural land degradation and identifying possible policy responses as well as directions to overcome the farmland and related resources degradation challenges. This study employed multiple data sources and a combination of policy documents, spatial data and information from the field through structured observation were utilized. Based on the land policy analysis, the major bottlenecks on efficient and effective implementation of the policy directions and legal frameworks were lack of awareness and sense of ownership; specific land use policy; institution responsible for land administration and use, to support and coordinate stakeholders efforts; mechanisms to build the capacity of implementers, beneficiaries, and how to disseminate the information for the public; attention for research and development to prepare land use plan in line with the dynamism of land use and cover change. Rights to use of common-pool resources were also a neglected aspect of land policy. Particularly in the Benshangul-Gumuz region, the majority of the local communities depend on common-pool resources such as forest lands, rangelands and wetlands for their livelihoods. On top of this, there were some constraints in the legal frameworks of the region: enforcement mechanisms for violations of the provision on land management are referred to relevant institutions and bodies; customary land right is not properly recognized in proclamations; and the ceiling for holding size not determined based on the in-depth study of the agro-ecological conditions, farming practices and customary landholdings system in the region. Thus, policymakers need to consider these drivers and make sound decisions during decision makings.","PeriodicalId":16368,"journal":{"name":"Journal of Natural Sciences Research","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83951846","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}

Two improved fodder oat varieties (Bate and Bonsa) were demonstrated on purposely selected AGP II districts namely; Boneya Boshe, Wayu Tuqa, Guto Gida, Diga, and Horro districts of East and Horro Guduru Wollega zones, respectively. One peasant association (PA) was selected purposely from each district based on forage production potential and compatibility with AGP II criteria. The experiment was demonstrated on a simple plot with a size of 10 x 10 m. Forage dry matter and grain yield data, and farmer perceptions and preferences were collected and analyzed by simple descriptive statistics and pair-wise ranking technique. The varieties showed remarkable variation in their dry matter and grain yield potential across the testing areas. The average dry matter yield performance of the Bate (4.67 t/ha) variety obtained from the farmer's field was relatively higher than Bonsa (4.19 t/ha) variety used as a standard check. Similarly, the average grain yield performance recorded for Bate (31.24 qt ha -1 ) variety was also higher as compared to Bonsa (25.02 qt ha -1 ) variety. Based on the procedure of variety evaluation and selection criteria, farmers set their criteria to evaluate, rank, and select the best variety following the real situation existing. Thus, against each of the criteria and weight attached, Bate variety was selected and ranked first for its high dry matter and grain yield, tolerance to disease and lodging, and leafiness as compared to Bonsa variety. Therefore; it is important to scale up this variety on a larger scale to improve the availability of quality feed and boost the production and productivity of livestock in the area.","PeriodicalId":16368,"journal":{"name":"Journal of Natural Sciences Research","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79499806","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}

In Ethiopia much of the increase in crop production in the past decade has been due to increases in area of cultivated. To what extent expansion can continue remains a question, therefore obtaining higher yield rates is the challenge of Ethiopia’s agricultural system. Conservation agriculture (mulching); which here refers to minimizing soil disturbance through no-till practice, application of organic mulch cover, and cropping in time; has the potential to improve soil quality, water, and crop productivity. The objectives of this critical review is to collect available information in similar production environments, indicators on the essential of CA contributions to soil quality, crop and water productivity both in dry and rainfall seasons of Ethiopian agriculture. Recently a study on the role of conservation agriculture indicates improve soil quality, crop yield and water productivity. In addition to this CA can be protect soil layer for erosions either wind or runoff, to optimize infiltration rate minimize runoff, to crate the path of soil it contributes micro nutrients move easily. So, reviewer concluded that conservation agriculture is potentially important to improve sustainable Ethiopian agricultural production and productivity. This agricultural practice (CA) should be able to adopt for irrigated and rain fed farms of Ethiopia.","PeriodicalId":16368,"journal":{"name":"Journal of Natural Sciences Research","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79176291","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}

It is the world’s fourth most widely cultivated food crop after wheat, rice and maize. Ethiopia has considerable potential for potato cultivation, as 70 percent of its arable land is suitable mainly highland areas above 1500 meters of altitude. Also, the country is one of the major producers in Eastern Africa because of its suitable agro-ecology and its domestic consumption levels. The main objective of the review was to know potato production and marketing status by small holder farmers in Ethiopia. The data were collected from secondary sources mainly from FAOSTAT, CSA and different published materials on production and marketing chain in Ethiopia. The general idea of the review shows that Ethiopia has potential for potato production but lack of certified improved seed for potato producers, local seed multipliers have limited access to information and depend on low-quality local potato varieties selected and multiplied according to individual knowledge, the high cost of agro-chemicals either refuse to purchase fertilizer or apply inadequate amounts per hectare. In addition, the use of the same type of chemicals repeatedly allows pests and diseases to develop resistance. The major constraints of potato marketing involve poor storage and handling and low upgrading strategies to the commodity. Lack of market information providing institutions, higher input price, multiple taxes, and chemical herbicides, adulteration, absence of road service, poor product quality and high cost of input, weak market linkages among market. Therefore, the government and other concerned bodies should focus on increasing production and productivity of potato which in turn focused for establishing well potato market development for mutual benefits of all actors.","PeriodicalId":16368,"journal":{"name":"Journal of Natural Sciences Research","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90975490","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}
