The analyzed results showed significant differences in some growth and yield parameters measured. On the whole, performance of the foliar fertilizer treatments compared with the recommended soil-applied fertilizer treatments was good. Amongst the foliar fertilizer treatments also, application of 150 ml Boost Xtra/15l H 2 O output was better than its other foliar fertilizer treatments. The entire results suggest that it is possible to utilize foliar fertilizer in the cultivation of rice and also the application of foliar fertilizer at a rate of 150 ml Boost Xtra /15l H 2 O either at (basal + panicle initiation) or (basal + panicle initiation + Heading) could be an option for adoption in the cultivation of rice.","PeriodicalId":7540,"journal":{"name":"African Journal of Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41599469","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 causes severe damage and economic losses in tomato production. This study, conducted in four sites (Loumbila, Ouagadougou, Pabré and Tanghin-Dassouri) in the central zone of Burkina Faso, assessed the density of T. evansi over two growing seasons and evaluated the infestation levels through the tomato growth cycle from planting up to harvest. Mite’s population was assessed weekly from March to May durinrg the dry season and from August to October for the rainy season in Burkina Faso. We found a high density of T. evansi during the hot and dry periods, corresponding to increase temperatures. The Loumbila, Pabré, and Tanghin-Dassouri sites show a similar density of the mite’s population and generally have an average of fewer than 20 individuals per leaf compared to the site in Ouagadougou with a density of more than 80 individuals per leaf. In contrast, during the rainy season, which is characterized by high humidity, densities of T. evansi were as low as 10 individuals per leaf. We also found that, when climatic and environmental conditions are favorable, all growth stages of the tomato are attacked by the pest.","PeriodicalId":7540,"journal":{"name":"African Journal of Agricultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48007871","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}

Experienced operators were involved during field experiments to investigate and establish the magnitudes of hand-transmitted vibration experienced by single-axle tractor operators with and without vibration reduction isolators during tillage operation. The results indicated that the magnitudes of vibration total values were 5.694 m/s 2 at approximately 1500 rpm on stationary mode, 6.972 and 7.985 m/s 2 at 1.5 and 2.7 km/h respectively during tillage operation. The use of rubber with metallic washers as vibration reduction isolators result in a significant reduction in magnitudes of vibration total values to 3.656 m/s 2 in stationary mode, 4.365 and 4.958 m/s 2 at 1.5 and 2.7 km/h respectively during tillage operation. The National standard TZS 1471 (2018) and ISO 5349-2 (2001) warns that, the exposure to higher magnitudes of vibration presumably carries increased health risk towards vibration-induced disorders and other occupational hazards associated with body fatigue. These call for collaborative efforts among design engineers, researchers, and the research and development organizations to further study the human-machine interaction behaviour of single-axle tractors and human engineering data to ensure human safety, satisfaction of the single-axle tractor operators and ensure safe and healthy working environments.","PeriodicalId":7540,"journal":{"name":"African Journal of Agricultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42631690","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}
