Abstract:
The recovery percentages and out-turns of diverse coffee cultivars are contingent upon distinct processing methods and fruit characteristics. Despite the availability of numerous coffee varieties, their recovery percentages and out-turns remain untested in the Gulmi District of Nepal. This study aimed to assess the recovery percentage of different coffee varieties in the Gulmi District to provide insights into the most productive varieties for local farmers, investigate the influence of processing techniques on the recovery percentage, and evaluate the potential for improving the recovery perc

Abstract:
Nigeria, a nation with abundance of natural resources, has over the years generated its major revenue from the export of crude oil, one of its leading natural resources, obtained from different Oil fields in various states of the country. Revenue generated from this export constitutes the greater percentage of the country’s gross domestic product (GDP) as a result of the local and international transactions involved in the transportation of this product. A good percentage of these Oil fields have been exploited while some are yet to be utilized. However, it has become an issue of great concern
