Effects Of Storage Container and Storage Condition on Seed Health Quality of Common Bean Variety Ennepa in Southern Ghana

Keywords: Plastic container, polythene bag, ambient environment, cold environment, Aspergillus flavus, Penicillium spp


Common bean (Phaseolus vulgaris L.) has been introduced in Ghana for cultivation; however, yields on farmers’ fields are low due to poor seed health quality resulting in poor plant stand. This study determined the effect of storage containers (polythene bag vs plastic container) and storage environment (ambient vs cold storage temperature) on the seed health quality of common bean seeds stored for eight months. The fungal species and loads on the seeds were determined using the blotter method at 0, 2, 4, 6, and 8 months after storage. Aspergillus spp., Penicillium spp., and Rhizopus spp. were the major fungi recorded during storage. Seeds stored in plastic containers under an ambient environment showed a significantly lower incidence of Aspergillus flavus than the other treatments. Seeds stored in polythene bags under an ambient environment significantly lowered the incidence of A. niger. Seeds stored in polythene bags recorded a significantly higher incidence of Penicillium spp. after two months in storage irrespective of the storage condition. The lowest incidence of Rhizopus spp. was observed in seeds stored in plastic containers in an ambient environment. There was no observed insect infestation in storage over the eight-month duration. Seeds of the common bean variety Ennepa can safely be stored in a polythene bag under an ambient environment (25.43-29.660C).

Dr. Ernest Assah Asiedu

Dr. Ernest Assah Asiedu was the past Chief of Party of the West Africa Seed Program (WASP) of the West and Central Africa Council for Agricultural Research and Development (CORAF) with its Secretariat at Dakar, Senegal. Dr. Asiedu holds the B.Sc. degree in Crop Science from the University of Ghana (1979-1981); M.Sc. in Seed Technology, minor in Plant Breeding from Mississippi State University, USA, (1984-1986), and Ph.D. in Seed Physiology from University of Aberdeen, Scotland, UK, (1992-1996). Dr. Asiedu started his carrier with the Council for Scientific and Industrial Research – Crops Research Institute (CSIR-CRI), Ghana from 1981 to 2006 and rose to the level of Chief Research Scientist.
At the CSIR-CRI, Dr. Asiedu headed the Seed and Biotechnology Division and was the Counterpart Coordinator for the GTZ (now GIZ) funded West Africa Seed Development Unit(1996to2004). Dr. Asiedu pioneered the establishment of the Ghana National Seed Committee, the National Variety Release Committee in 1989 and the reformation of the seed sector from public sector led to private sector inclusion. After working for CSIR-CRI for 25 years, he joined CORAF in 2006 as the Cereals Network Coordinator for West Africa (2006-2007), as the First Manager for the Staple Crops Program, West and Central Africa (2007-2012), Chief of Party for WASP (2012 to 2017) and the Partnership for Agricultural Research and Education (PAIRED;2017-2018). Whiles at CORAF/WECARD Dr. Asiedu supported the design and management of thirteen regional agricultural projects to improve the productivity of major cereals, legumes, roots and tubers and plantain value chains under the partnership with USAID, AusAID (now DFAT), DFID, the World Bank and West Africa Agricultural Productivity Program (WAAPP); over 50 students were anchored to these projects leading to post-grade degrees. As the Chief of West Africa Seed Program, he supported the implementation of the ECOWAS Seed Regulation in 17 Member States, networking and capacity development in the seed sector which resulted in increased supply of certified seeds in West Africa from 12% in 2012 to 25% between 2012 and 2016. Dr. Asiedu coordinated the Agricultural Rehabilitation Seed Program for Liberia, Sierra Leone and Guinea to curb eminent famine and economic decline during and after the outbreak of the Ebola Virus Diesease. He has presented papers at international, regional and national conferences and workshops and has 39 scientific publications and several articles, manuals and materials to his credit, covering plant breeding, seed quality improvement and seed and agriculture sector development.
