Prof. Peter Kisinyo – DEAN, SANRES

Agribusiness constitutes the knowledge and principles of agriculture, science, economics and business for the production, processing and marketing of agricultural commodities. It exists on the foundation of the entire agricultural value chain extending from farm inputs, through on-farm businesses, to processing, transportation, credit and marketing. Within the agriculture industry, “agribusiness” is used simply as a blend of agriculture and business, referring to the range of activities and disciplines encompassed by modern food production. The Bachelor of Science Agribusiness Management offers a combination of Agricultural, business and Social Sciences required for the management of agribusiness and related institutions. The program offers better prospects for employment in the smaller and upcoming agro-industries that may not have the resources to employ specialists in Human Resource Management, Accounting, Production and Marketing. This program, among other objectives, aims to create a paradigm shift from government-driven production programme to market-centered business; from agricultural graduates looking for employment after college to agri-business innovators and job creators; from basic research to applied research among other transformations in the agriculture industry

PRESS RELEASE – CROP TRUST: Sorghum breeding with Wild Relatives: Evaluating pre-breeding material with farmers in Kenya

The launch of CROP TRUST-Sorghum project that will participatorily evaluate pre-breeding sorghum materials with farmers in Kenya at KALRO-Kibos research station beginning Long rain season of March-December 2018 and Later in selected farmers fields.


Dr. Evans Ouma, Lecturer, Department of Agronomy and Environmental Sciences

The collaborators of this project include; Ugenya Banana farmers group, Aminyasa youth group and Dr. Eva weltzien who is independent consultant. The key beneficiaries will be the farmers who rely on sorghum for food security and income in the face of climatic and demographic stresses. Others include breeders who will get opportunity to work with increased genetic diversity because of exploitation of the new gene pool from the wild relatives. The challenge is to obtain early, high yielding, drought-, disease- and insect-tolerant varieties with high adoption rates and capacity building for all partners.

All materials and related data will be made available to the global community. This work was undertaken as part of the initiative “Adapting Agriculture to Climate Change: Collecting, Protecting and Preparing Crop Wild Relatives” which is supported by the Government of Norway. The project is managed by the Global Crop Diversity Trust with the Millennium Seed Bank of the Royal Botanic Gardens, Kew UK and implemented in partnership with national and international genebanks and plant breeding institutes around the world. For further information, please go to the project website: http://www.cwrdiversity.org/
