The low productivity of wheat in Ethiopia is mainly attributed to lack of improved agronomic practices. Nitrogen and phosphorus are the major important elements for crop yield. But there is lack of information on optimum fertilizer rate for wheat production in this area (Kofele district of West Arsi zone). Therefore the objective of this research was to determine the optimum nitrogen and phosphorus fertilizer rate for wheat at Kofele district. This experiment was conducted for two consecutive years in 2016 and 2017 main cropping season. The treatment has two factors (three bread wheat varieties:- Digalu, Dendea and Didase and fertilizer rates: - 73kg/ha of nitrogen and 69kg /ha of P₂O₅, 109.5kg/ha of nitrogen and 103.5kg/ha of P₂O₅, 146kg/ha of nitrogen and 138kg/ha of P₂O₅and 46kg/ha of nitrogen and 181kg/ha of NPS:-19:38:7). The analyzed data indicated that plant height and seeds per spike of bread wheat was highly significantly affected by main effect of variety. Highest plant height (128.33cm) and seeds per spike (42.1) were recorded from variety Dendea. Spike length was significantly affected by main effect of variety. The longest spike length (8.3) was recorded from variety Hidase. Wheat grain yield was significantly affected by interaction effect at (p<0.05). Variety Hidase produced the highest grain yield of 6904.4kg/ha at 146kg/ha of nitrogen and 138kg/ha of P₂O₅. Above ground dry weight of wheat was significantly affected by interaction effect. The highest above ground dry weight 18.9 ton/ha of wheat was produced from variety Digalu at 73kg/ha of nitrogen and 69kg/ha of P₂O₅. Therefore, to get the highest benefit farmers should grow variety Hidase by applying 146kg/ha of nitrogen and 138kg/ha of P₂O₅at this area.\u0000","PeriodicalId":16806,"journal":{"name":"Journal of Plant Sciences","volume":" 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140991427","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}

Among the constraints, coffee diseases attacking fruits, leaves, stems and roots that reducing coffee yield and marketability are economically important across the country. Coffee thread blight disease considered as a minor for 40 years in Ethiopia is currently emerging as a significant bottleneck to the sector. Recently, the occurrence and significant damage due to this disease have been frequently reported from different coffee production areas. However, there is the lack of profiled information on intrinsic and extrinsic character of the pathogen. Hence, this study was initiated to determine the effect of temperature and artificial media on the growth and sporulation of C. koleroga. Collected sample from Metu sub-center have been isolated and purified. Then after, purified isolate was characterized on five different artificial media namely PDA, MEA, Sabouraud, yeast and Czapeck and three temperatures (20, 25 and 30°C) ranges for growth and sporulation. The result revealed, there was a significant difference (P<0.001) among media and temperature ranges in the sporulation and radial growth rate of the pathogen. The fastest radial growth 3.57 and 3.51mm/day was recorded from PDA and Sabouraud media when incubated at 25°C, respectively. Whereas, the lowest growth rate was observed on yeast extract agar. On the other hand, the highest spore amount (116 spores/ml) was recorded from Sabouraud medium followed by potato dextrose agar and Yeast extract agar media at 25°C. The study confirmed that the three media (Sabouraud, Yeast extract agar and potato dextrose agar) with 25°C temperature are the best combination for proper radial growth and sporulation of Corticium koleroga. In general future studies should focus on alternative intrinsic and extrinsic factors for the growth and sporulation of this pathogen.\u0000","PeriodicalId":16806,"journal":{"name":"Journal of Plant Sciences","volume":" 54","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140993630","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 aim of this study was to evaluate the antifungal potential of <i>Cymbopogon citratus</i> essential oil against <i>Alternaria alternata</i> and <i>Phomopsis carica-papayae</i>, fungal agents associated with the deterioration of papaya leaves in the Moungo region of Cameroon. The essential oil of fresh <i>C. citratus</i> leaves was extracted by hydrodistillation.

The MIC of 700 ppm proved fungicidal on <i>P. carica papayae</i>, while for <i>A. alternata</i> the fungicidal effect was obtained at a concentration of 900 ppm. <i>In situ</i>, the essential oil proved significantly active in inhibiting necrosis caused by the conidial complex of the two pathogens on papaya leaves, with a percentage inhibition of 85.93% at a concentration of 6000 ppm. <i>C. citratus</i> EO could therefore be used as an alternative to chemical fungicides in the fight against papaya leaf disease pathogens.\u0000","PeriodicalId":16806,"journal":{"name":"Journal of Plant Sciences","volume":"47 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140259086","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}
