INFLUENCE OF DAYS COCOA PODS SPEND ON THE GROUND AFTER HARVEST AND DRYING BY SOLAR DRYER ON THE QUALITY OF COCOA BEANS
Abstract
Abstract This project was carried out at the Department of Agriculture Engineering and Mechanization of the College of Agriculture Education, Mampong Ashanti of the University of Education, Winneba. It was to determine the number of days cocoa pods should spend on the ground after harvesting before breaking so as to maintain high quality cocoa beans. It was also to determine the quality of cocoa beans when dried with solar panel. Hybrid cocoa pods were left on the ground for varied duration after harvesting. The pods were broken to remove the beans, fermented and dried using direct sun and solar panel. Quality test was carried out on the dried cocoa beans. The results showed that cocoa beans took lesser days to dry with solar panel than direct sunlight. Cocoa pods that spent eleven (11) days or more on the ground produced higher defective beans with lower quality and sub-standard grade. The pods that spent less than eleven (11) days on the ground produced cocoa beans of good quality. Cocoa beans dried with solar panel were more acidic and were of a higher purity. It is recommended that cocoa pods be broken and processed within eleven (11) days after harvest. During cloudy and rainy weather farmers are advised to dry their cocoa beans using solar panels. Key words: Grading, Cocoa bean category, defects, mouldiness, slatiness, solar panel

Essilfie, M. E., Dapaah, H. K., Tevor, J. W. & Darkwa, K. (2016). Number of Nodes and Part of Vine Cutting Effect on the Growth and Yield of Sweetpotato (Ipomoea batatas (L.) Lam) in Transitional Zone of Ghana. International Journal of Plant & Soil Science, 9,
Abstract
Abstracts Two field experiments were conducted at the Multipurpose crop nursery of the University of Education, Winneba, Mampong campus from May to September, 2013 and June to October, 2014 respectively to investigate into the effect of number of nodes (4, 5 and 6) and vine part (apical and semiwoody) on the growth and yield of sweetpotato. The results from both seasons showed that many of the characters measured increased with increase node number up to 6 nodes and with apical vine part. The apical vine cuttings established earlier than semiwoody cuttings in both seasons. Node numbers did not have significant effect on any of the yield characters measured although the 5 and 6 node cuttings gave higher marketable tuber weight per plot, tuber length and marketable tuber number per plot than the 4 node cuttings during 2014 growing season. The 5 node apical cuttings produced significantly higher vegetative biomass than 5 node semiwoody and the 4 and 6 node apical and semiwoody cuttings. Keywords : Sweetpotato; apical vine cutting; number of nodes; semiwoody vine cutting.
