Essandoh-Yeddu, J.
The development of a country is to a large extent dependent on the optimal development and utilization of its energy resources and the provision of energy services in a reliable, cost-effective and environmentally friendly manner. Recognizing the importance of energy to national development, Past and present governments have been struggling with establishing the most optimal administrative infrastructure both soft and hard to execute and implement policies to achieve such an energy vision. The Energy Sector since its formal establishment has come up with a number of policies to promote the sector as well as addressing the challenges. These include the Power Sector Reform in the 1990s to help attract private investment into the power subsector value chain; the 2001 Energy Policy which focused on poverty alleviation and economic growth; and the 2010 Energy Policy necessitated largely by the discovery of oil in substantial commercial quantities in 2007 and which provided the initial framework for the development and utilization of indigenous oil and gas resources in the country. There have been significant changes in the national and global energy landscape. The country had also undergone years of frequent power outages and planned power rationing across the country in the past, and the severest and longest occurred from 2013-2015, leading to reduced workforce productivity, unreliable supply of electricity, relatively high electricity tariff compared to the last decade culminating in the high cost of doing business, etc. These have compelled recent and present governments to come up with restructuring of the sector on a number of occasions. The presentation is a discourse on the entire Energy Sector and the challenges since the immediate colonial era to what prevails today. It will also touch on the potential opportunities for the country and job prospects in the sector.

Abaidoo, C.
Science research and Innovation are key to national development especially in an era of expanding global market and the growth of knowledge based resources. In Africa, one of the underlying setbacks for our development is the slow pace of innovation and technology development. However, exploitation of the Intellectual Property Right (IPR) system presents one of the greatest opportunities for scientists and researchers to create wealth for themselves and contribute to the innovation eco-system. This paper, therefore, seeks to expose the participants to IPR creation and management with emphasis on patenting and utility models

We conducted a study to determine the response of Late Valencia sweet orange to organic and inorganic fertilizer application for two seasons in the semi-deciduous forest agro-ecological zone of Ghana. The experiment which was conducted in a randomized complete block design with four replications consisted of six treatments: 9 t/ha oil palm empty fruit bunches (EFB); 4t/ha Poultry manure (PM); NPKZn (90kg/ha N, 60kg/ha P, 80kg/ha K and 4.8kg/ha Zn); 4.5 t/ha EFB+NPKZn (45kg/ha N, 30kg/ha P, 40kg/ha K and 2.40kg/ha Zn); 2t/ha PM + NPKZn) (45kg/ha N, 30kg/ha P, 40kg/ha K and 2.40kg/ha Zn) and Control. In the 2019 harvest season, the treatment PM+NPKZn recorded the highest yield of 14.71t/ha while the control recorded the least yield (6.37t/ha). In the 2020 harvest season, fruit yield ranged from 17.3 t/ha with the NPKZn treated plots 28.8t/ha with the EFB treated plots to. Economic analysis shows that for the five fertilizer application treatments, the highest benefit/cost ratio was attained with the EFB treatment for the two harvesting seasons combined. Fertilization did not significantly affect leaf nutrient content 253 days after application. However, leaf N and K contents were generally higher 253 days after fertilizer application than the initial levels while P level did not change. Soil analysis 253 days after nutrient application showed an increase in total N, OC and available P while pH level decreased. The study suggests the need for farmers to adopt the use of crop residues for maintaining soil fertility of citrus orchards for improved fruit production.

Cassava mosaic disease (CMD), arguably the most important viral disease of cassava, an important food security crop has in recent times been reported to be associated with satellites in some parts of sub-Saharan Africa. This study investigated the status of cassava mosaic begomovirus and associated satellites in CMD-affected cassava plants in Ghana using species specific primers in polymerase chain reaction. In all, 110 CMD-affected cassava leaf samples were collected along some selected routes in the southern parts of the Country. Africa cassava mosaic virus (ACMV) was detected in 107 (97%) cassava leaf samples, out of which 74 (69 %) was in mixed infections East Africa cassava mosaic virus-Cameroon (EACMV-CM). EACMV (CM) alone was detected in 3 (3%) cassava leaf samples. Out of the 110 cassava leaf samples affected by cassava mosaic begomoviruses, satIII was present in 73 (66%) of the cassava leaf samples whereas 47 (43%) sample tested positive for satII. Detection of CMB-associated satellites in Ghana is to the best of our knowledge the first in the country and possibly in West Africa, and has serious epidemiological implications on the management of CMD therefore requiring further studies and concerted efforts to safeguard cassava production
