Soil erosion is one of the several major deteriorative processes which results in soil degradation and declining agricultural productivity in Ethiopia. Thus, several efforts to control soil erosion through introduced soil and water conservation measures had been conducted in different time and location in the country. A number of soil and water conservation methods were introduced to combat land degradation, but adoption of these practices did not achieve the target. Different soil and water conservation measures and farmer’s adoption barriers on these conservation measures had been reviewed here. Literature indicated that soil and water conservation measures have promising effects on reducing soil loss, retaining nutrient and soil moisture, improving soil physical and chemical properties. But an intensive labour requirement, poor design, reduced land size and other biophysical and socioeconomic factors discourage farmer’s adoption of soil and water conservation structures. The involvement of Farmers and strengthen extension workers as well as mainstreaming soil and water conservation activity in any agricultural development project has a vital role in these resource conservations.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122773407","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 a potent greenhouse gas with a global warming potential 25 times more than carbon dioxide. Methanogenesis is the biological production of methane mediated by anaerobic microorganisms from the domain Archaea commonly called methanogens. These methanogens are different from bacteria and eukarya as they lack peptidoglycan in their cell wall, which is present in bacteria and eukarya. Methane is produced by three major pathways on the basis of substrate utilized for methane production: hydrogenotropic, acetoclastic and methylotropic. Out of these, hydrogenotropic and acetoclastic are the two predominant pathways. There are two major sources of methane; namely, natural and anthropogenic. The natural sources include wetlands, termites and oceans, whereas, the common anthropogenic sources are fossil fuel transport and distribution, livestock, rice fields, and landfills. Among anthropogenic sources of methanogenesis, livestock which is ruminal methanogenesis is the major and it contribute to global warming and gross energy feed intake loss about 10-12%. The role of methanogenesis to ruminant animals is to remove hydrogen (H2) from the rumen. Methanogenesis can also beneficially exploit to treat organic wastes to produce useful compounds and methane that can be collected as biogas.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122222898","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}

Their study, however, is hampered by their underground development, and characterizing complex root system architecture, hence, remains a challenge. Nowadays, a number of methods have been utilized to estimate root growth. Specialised, are costly for reproduced pot experiments, and aren’t promptly available for a nondestructive sampling of roots and soil. Here, Employing a Novel Cheap Rhizotron for Root Growth System Analyses on Plants. The root image securing using cheap technology Due to the inaccessibility of root systems, special methods are required to explore the dissemination and dynamics of roots. Utilizing this Rhizotron development, growth of the response the chickpea (Cicer arietinum L.) and Lentil (Lens culinaris Medik) under the hydroponic systems were explored. Significant differences in both architectural and morphological characteristics were observed among tested genotypes, especially for add up to root length, branch number, and particular root length and department thickness. It comes results illustrated that the framework was effective in screening root characteristics, permitting for rapid measurement of dimensional root architecture over time with negligible unsettling influence on plant growth and without destructive root sampling. The setup allows us to simultaneously characterize the root system and shoot development seedling stages. All components of the system are made from commodity components, locally available worldwide to facilitate the adoption of this affordable technology in low-income countries and detailed methods of construction allow researchers to construct and use similar Rhizotrons for experimental research.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"33 7-8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116472866","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}

Cotton-seed quality is affected, to a large extent, by the indeterminate growth habit of the cotton plant, which allows seed to set and develop across an extended period of time. Seed vigor and viability are important components influencing seedling establishment, crop growth, and productivity. Any factor that negatively affects seed vigor and viability during seed development will have adverse consequences on crop production. Plant nutrition using a balanced fertilization programmer with both macro- and micro-nutrients has become very important in the production of high-quality seed. Plant growth retardants (PGR,s) represent diverse chemistries and mode of action, and provide numerous possibilities for altering crop growth and development, provide farmers with a new management tool for controlling undesirable vegetative growth, and to balance vegetative and reproductive growth as well as to improve yield and its quality [1]. Seed quality is one of the most important factors for stand establishment in cotton (Gossypium Sp.), and the use of good quality seeds is therefore essential to obtain an optimum plant population. Conditions prevailing during seed formation can affect the quality of seed produced, and hence crop establishment in the next growing season. These conditions can affect the germination of the seeds and the ability of the seedlings to emerge from soil, these being the most critical stages during the life cycle of cotton plant. Field experiments were conducted to investigate the effect of nitrogen (N), phosphorus (P), potassium (K), foliar application of zinc (Zn) and calcium (Ca), the use of plant growth retardants (PGR’s) [e.g., 1, 1-dimethyl piperidinium chloride (MC); 2-chloroethyl trimethyl ammonium chloride (CC); or succinic acid 2, 2-dimethyl hydrazide (SADH)], during square initiation and boll setting stage, on growth, seed yield, seed viability, and seedling vigor of cotton [1].","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131420493","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}
