The usage areas of nanoparticles including cosmetics, paints and coatings, plastic additives, communications, electronics, sensors, packaging, biomedical diagnostics, textiles, antibacterial agents are quite wide. For this reason, the release of nanoparticles to the soil directly or indirectly through air and water is gradually increasing. Therefore, the soil is contaminated with nanoparticles in the long term and soil microorganisms can adversely be affected by these accumulated nanoparticles. Soil microorganisms play vital roles in soil carbon cycling, nitrogen fixation, and nutrient acquisition for plants. Nanoparticles can show different toxic effects on soil microorganisms according to their physical and chemical structures. Also, the humic acid, organic matter, pH, and ionic in the soil strengths affect the toxicity of nanoparticles. Nanoparticles may show toxic effects on soil microorganisms directly or indirectly, such as changes in the bioavailability of toxins or nutrients, toxicity due to their interaction with natural organic compounds or toxic organic compounds. Also, nanoparticles can have a lethal effect on soil microorganisms by causing the production of reactive oxygen species by damaging the membrane permeability, cell signaling processes, and the stability of enzymes and protein structures. The effect of nanoparticles such as C6 0 fullerenes, Fe2 O3 , Ag, ZnO, CeO2 , TiO2 on soil microorganisms and the mechanisms of their toxicity are comprehensively reviewed and discussed in this mini-review.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126149891","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}

Lam.) is one of the globally important root crops. In Ethiopia, its production is confronted with lack of planting materials, shortage of farmer preferred varieties, poor extension system among many other constraints. The study was conducted to assess the performance of different released varieties at Teppi. Evaluation of the varieties was carried out in main cropping season. Each treatment was replicated three times and arranged in Randomized Complete Block Design. Stand count at harvest, number of roots per plant, plant height, total root yield, root length and root diameter were measured. All the traits showed significant difference between varieties. The highest root yield (50.83 t/ha), root length (24.77 cm) and root diameter (10.35 cm) were recorded for the variety Awassa-83. The lowest root yield (27.67 t/ha), root length (8.9 cm) and root diameter (4.75 cm) were recorded for the variety Cemsa, Beletech and Temesgen, respectively. The highest number of roots per plant (4.03) was recorded for the variety Cemsa and there was no significant difference observed between other varieties. The findings of the study revealed that, Awassa-83 was found to be more adapted to the area as compared to other varieties. This variety should be popularized and disseminated to users to boost the production and productivity of Sweet Potato in the area.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121861704","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}

The mineralogy of soil samples was determined by X-ray diffraction (XRD). X-ray Fluorescence (XRF) and Inductively Coupled Plasmas-Mass Spectrometry (ICP-MS) have been used to determine major and trace element including rare earth elements compositions of granite and soil samples. Granite samples consist of feldspars (orthoclase, plagioclase), quartz, biotites and opaque minerals. They have peraluminous composition and of S-type granite. They also have high contents in Ba, Cr, Sr, Zr and low REE contents with variable Eu anomaly values. The mineralogical and geochemical features of Vertisols corroborate with the parent rock nature and the intensity of weathering process. The Fe-oxide precipitation, the presence of kaolinite and calcareous nodules are responsible for significant contents in Fe2O3, Al2O3 and CaO, respectively. Several major and trace elements are accumulated at the bottom of the profiles. The accumulation of clay increases with REE contents from the upper to the lower horizons in Vertisols of Kaele area. LREE-enrichment in Vertisols is inherited from the parent material and probably preserved by the formation of secondary LREE-bearers. The low REE contents may result from depletion of REE rich minerals as in the parent rocks despite the REE remobilization during weathering. REEs how coherent geochemical behavior and low solubility during weathering. The variable Eu anomalies can be explained by the variable behavior of Eu-bearers while Ce anomalies exhibit the variability of the oxidation conditions. The low (La/Yb)N values and the similarity of the spectra of mass balance calculation in most of the profiles are linked to the environment which is not well drained and the homogenization of the profiles by seasonal deep surficial desiccation cracks.","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121416797","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}

The study determined farmers’ response to poultry extension services in Owerri agricultural zone Imo state Nigeria. Poultry farmers would not break even in their business enterprise without adoption of improved techniques of farming. One hundred and twenty farmers were randomly selected for the study and data were analyzed using descriptive statistical tools such as percentage, mean, frequency and multiple regression at 0.1 level of significance (ordinary lean square analysis). The results revealed that education was an important factor that determined farmers participation in extension programmes. Young farmers were also more receptive to extension programmes. The results also revealed that their major sources of information were from extension agents 2.7 and fellow farmers 2.6. The farmers also adopted the use of improved breeds, regular litter replacement and regular vaccination of birds with a mean of 2.8 respectively. They however did not adopt the use of artificial breeds. Their major constraints to the adoption of innovation were finance and high cost of livestock feeds. In recommendation, farmers were encouraged to form co-operative societies to enable them access loans from financial institution.a","PeriodicalId":194042,"journal":{"name":"World Journal of Agriculture and Soil Science","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114857822","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}
