Brief history

Horticulture as a discipline has been part of B.Sc. programme in the Faculty of Agriculture since its inception in 1970. One of the pioneer lecturers who taught the horticulture courses was Prof. Kimani Waithaka who later became the Chairman of the then Department of Crop Science and subsequently the Dean of the Faculty of Agriculture. Prof. Waithaka was a pioneer biotechnology specialist in Kenya who trained the first cohort of tissue culture specialists in the country who later scaled up and out TC technology in Kenya and the region.  Until the late 1980s post-graduate training in horticulture was carried out under the M.Sc. Agronomy program which was approved by senate and implemented in 1974. In 1988, M.Sc. Horticulture program was initiated and has since trained key personnel for the Ministry of Agriculture, Universities, research institutions, public regulatory organizations and the private sector. The M.Sc. Horticulture program in the Department of Plant Science and Crop Protection is offered in full time and part time mode.
