Graduate students from Guyana pursue degrees in agricultural regulations at UAPB


Three students from the University of Guyana are currently pursuing master’s degrees in agricultural regulations from the University of Arkansas at Pine Bluff (UAPB). In addition to regular coursework, they are fulfilling graduate assistantships through work on a UAPB project intended to increase the availability of high-quality sweet potato planting materials to limited-resource farmers both in Guyana and in the Arkansas Delta.

Ryan Nedd, Tiffanna Ross and Kenisha Gordon – all alumni of the University of Guyana (UG) in Georgetown, Guyana – are being trained in plant breeding, virus-indexing and other molecular techniques at UAPB’s state-of-the-art tissue culture laboratory. An integral part of the UAPB Sweet potato Foundation Seed Program, the laboratory allows researchers to develop and multiply virus-indexed sweet potato slips. The experience the students gain using UAPB’s resources will aid in the development of a similar facility in Guyana in the coming years.

“The UAPB School of Agriculture, Fisheries and Human Sciences (SAFHS) will greatly benefit from the contributions of these new recruits to the graduate program in agricultural regulations,” Dr. Edmund Buckner, interim dean/director for SAFHS, said. “Their work will strengthen sweet potato production in Guyana and help build applied research and international Extension capacity at UAPB.”

At the tissue culture lab, the students are working to breed sweet potato plants with better resistance to common diseases and pests. After hybrid plants are tested in the field, the plant lines deemed healthiest, and virus-free will be multiplied for distribution to farmers in Guyana.

“This project is important for both farmers in Guyana and Arkansas because our sweet potato lines are being developed to increase production and yields,” Gordon said. “Often hindered by lack of access to high-quality planting materials, small-scale and limited-resource farmers will now be able to use these plants to expand their farming operations and foster economic stability within rural areas.”

Ross said sweet potatoes are packed with nutrients and are an important part of food systems around the world. The increased production of sweet potatoes at local levels in the Delta and in Guyana can lead to health benefits for both populations.

“I enjoy the in-vitro development and multiplication of virus-free sweet potato plants for student research and production by farmers,” she said. “Just the thought of being a part of a program that aids in improving agricultural science and enhances food production is exhilarating and purposeful. Being able to carry out research on sweet potato DNA and explore new avenues of enhancing this crop for full utilisation of its inherent nutritional value is even more remarkable.”

Nedd said continued cooperation between UAPB, UG and organisations such as the National Agricultural Research and Extension Institute in Guyana will lead to more shared research opportunities for sweet potato crop enhancement. While studying at UAPB, he appreciates the balance between field research opportunities and lessons learned in the classroom.

“The agricultural regulations curriculum gives UAPB students an edge in learning how to deal with current agricultural and environmental issues, as well as using research to make wiser decisions for the future,” he said.

Ross said the agricultural regulations degree program is structured to give students a broad familiarity with a wide range of subjects including molecular biology, biochemistry, biotechnology, plant breeding, food safety and food microbiology. The versatile nature of the curriculum ensures students can be hired in a number of areas after graduation. To further prepare students for their future careers, the course hours and requirements are designed to emulate the expectations of a professional in the field.

Gordon said she chose to pursue a master’s degree in agricultural regulations at UAPB to obtain a broad theoretical understanding and practical research experience in the area of food safety and related fields. She believes the degree will propel her toward her career goals of managing and increasing the awareness of agricultural food safety and quality assurance in Guyana.
